Elmhurst College, a small four-year schoollocated in a sleepy part of Chicagoland, doesn’thave a high-powered doctoral program in high-energy physics. It doesn’t have a huge staff ofprofessors instructing hundreds of physics stu-dents, nor teams of researchers engaged in par-ticle physics experiments all over the world.

However, what Elmhurst College does haveis Earl Swallow.

Swallow is head of the physics departmentat Elmhurst, the sole undergraduate-only insti-tution that has a faculty member and studentsengaged in high-energy physics research atFermi National Accelerator Laboratory. Andwhile Swallow has been at the forefront of par-ticle physics research during his 20 years as aprofessor, he still keeps his teaching commit-ment to both physics and non-physics majors ashis top priority.

For those students not planning a life in sci-entific research, yet still interested in the subject,Swallow enjoys expanding their knowledge ofphysics, hoping they will retain an appreciationfor the field regardless of their career choices—in government, business or other endeavors. For

Elmhurst College Breaks The Mold At Fermilab

physics majors, his instruction teaches that par-ticle physics is a fundamental part of the fieldand not an isolated niche, an impression pro-moted by some people outside the field, said theprofessor. Swallow added that Fermilab’s prox-imity to Elmhurst allows him to expand his cur-riculum and introduce students to the world’sforemost particle physics laboratory.

“We do things in which some studentswork on the experiments with me [at Fermilab]and some just visit. But I think I also bring itback here in terms of being able to discuss thekinds of advanced experimental technology weuse,” said Swallow. “I give them bits of real datato work on in the particle physics class, and Ithink that imbues what they’re studying asundergraduates with a lot more reality.”

He says his mission of teaching at Elmhurst,combined with a desire to stay active in researchat Fermilab, forces him to balance time andcommitments with great care. It’s a juggling actthat he has been doing since his earliest days asan assistant professor at Elmhurst.

Looking BackIn the mid–1970s, as a graduate student at

Washington University in St. Louis, Swallowparticipated in a hyperon beta decay experiment,one of the first studies with polarized hyperonsat Argonne National Laboratory. Swallow saidthis experiment was a watershed in his career,not for the physics involved, but because he collaborated for the first time with RolandWinston, then a new assistant professor at theUniversity of Chicago. Swallow and Winstonhave worked together ever since, includinghaving a hand in one of Fermilab’s newest fixed-target experiments set to run this summer.Winston said he enjoys working with Swallowbecause he is constantly trying to approach newchallenges in unconventional ways.

“When I first met him, I quickly discoveredthat he was extremely bright but also had anindependent way of thinking, and that’sextremely valuable,” said Winston.

In 1976, Swallow was working in a researchposition at the University of Chicago when hedecided that he wanted to teach at a small col-lege, while continuing his high-energy physics

greater accuracy.Fermilab provided that opportunity,

bringing the Elmhurst professor toBatavia for the first time.

In the early 1980s, Swallow andWinston joined Yale and Fermilab physi-cists to repeat the sigma minus beta decaystudy at a much higher precision level,with Swallow using a sabbatical to workon the experiment.

“That was the first experiment to getresults from the ‘EnergySaver/Doubler,’ which,of course, we are nowallowed to call theTevatron. At that point,we were not allowed tocall it the Tevatron”because it ran at about400 GeV and not 1TeV, said Swallow.Previous similar experi-ments that ran at lowerenergies yielded only afew hundred events; theFermilab experiment,E715, yielded about50,000 decays, allowingresearchers to gain aclearer picture of thephysics. The finalanalyses confirmed theStandard Model prediction.

The Move ToKaons

In the late 1980s,Winston and Swallowwere approached byBruce Winstein fromthe University of

Chicago, who asked if the two professorswanted to join a collaboration studyingCP violation in kaon decays. CP violationis the observed difference in the decay ofmatter and antimatter. The StandardModel has a place for CP violation, and,presently, kaon decays are the only way tosee it.

Swallow and Winston eventuallyjoined the CP violation experiment atFermilab. The research team foundresults consistent with no or relativelyminimal direct CP violation. However, asimilar experiment at CERN, theEuropean Laboratory for Particle Physics,found results that argued for substantialdirect CP violation. This prompted bothgroups to study the phenomenon further.

research. He eventually found a job atElmhurst College and two years laterbecame the physics department chairman.[The department has two full-time pro-fessors and several part-time instructors.The college graduates about four or fivestudents each year with physics degrees.]

Soon after joining Elmhurst, Swallowparticipated in more studies at Argonne,including a sigma minus beta decayexperiment with Winston and Tom

Romanowski, then at Argonne and OhioState University. Swallow said the studyproduced results that were somewhat sur-prising. Researchers found significant dif-ferences in some of the properties of thedecays, specifically in the correlationbetween the electrons coming out of thebeta decays and the spin of the sigma.Swallow said these results, although con-sistent with other experiments at thetime, were at odds with the StandardModel. The limited amount of data,however, caused Winston and Swallow towant to repeat the experiment with

The results “led us to say, ‘we haveto do this five or six times more accu-rately,’” said Swallow, “and that hasturned out to be a very big challenge.”

Continuing KaonsThe result of that challenge is KTeV

(Kaons at the Tevatron), a study that ispart of the Laboratory’s newest programof fixed-target experiments. KTeV com-prises two experiments, working in par-allel but studying different facets of CPviolation. E832 is aiming to repeat theearlier CP violation experiments six timesmore accurately. Phase II of E799 willstudy rare kaon decays and provide newhigh-precision hyperon beta decay data.Swallow said he is involved with both, asthe two studies hopefully will bring physi-cists—and the world—a step closer tounderstanding the prevalence of matterover antimatter.

“If we should find that direct CPviolation in [the] decays in E832...is stillcompatible with zero at a high precision,then, at that point, one doesn’t knowwhether there is a problem with theStandard Model or the parameters in theStandard Model conspire to give you asmall direct CP violation... In that case,further study of the rare decays becomesabsolutely crucial,” said Swallow.

Swallow said his time allotted to thisresearch is “modulated in big chunks.”The professor uses the summer and otherlong breaks from school to catch up onhis experiment. For this reason, he chosenot to take responsibility for any singlefacet of the KTeV experiment.

Swallow said he is not in a position atElmhurst to take on a large hardwareproject, so he keeps up with the progressof the experiment and, when he canmove back in, tackles a part of the devel-opment that needs his attention at thatpoint in the process.

“You are really not situated to do abig building project at a small institution.Between teaching and other duties, youtry to keep up with what is going on, soyou know what you are doing when youmove back in,” said the professor.

Swallow said two factors contributeto his ability to stay connected to his pro-jects and have a part in their success. Thefirst is working with “understanding col-leagues” like Winston, who accept hisunique situation. The other is the adventof the Internet and e-mail, which allow

A DOE committeeconducted the first majorreview, from May 7-9, ofthe DZero collaboration’sefforts to upgrade theirdetector in time for theresumption of colliderphysics in 1999. The 13-member panel, made up ofhigh-energy physicists fromuniversities and laboratoriesnot participating in theupgrade, met at Fermilab toaddress questions such asthose posed by chairmanand DOE staff member DanLehman: “How well definedis the overall upgrade pro-ject? Is the design [ofupgrade components] ade-quate to address the physics?Are the costs and schedulesas presented realistic?”

The meeting schedule was full. Participantsheld “working lunches” and attended eveningsessions. The rapid-fire agenda included projectmanagers’ presentations of cost estimates forupgrading or adding elements such as the sole-noid, calorimeter, and data acquisition systems,a review of schedule and funding considera-tions, a report from project management, andDOE panelists’ recommendations to projectmanagers regarding specific problems. On thethird day of the meeting, participants met for a“closeout” session. In this final wrap-up, thechairman urged members to have “a reallyopen exchange, so we’ll all understand whateach one is trying to say.”

Almost all DOE panelists began their sum-mary reports on component systems with aringing endorsement of the scientists and engi-neers. “The people are really good; they knowwhat they’re doing, and they made extensiveuse of SSC research and development,” saidRoger Rusack, of the team working on thefiber tracker. However, most groups were frus-trated by the dearth of engineering support. Atypical comment was that of Henry Lubatti,who reviewed the collaborations working onthe preshower detectors and the muon system:“Both groups urgently need a mechanical engi-neer.” In spite of the scarcity of engineers, pan-elists found that projects were mostly on

schedule and that “there are no show-stoppers.”

Although project managers have only beenable to predict the next year’s budget for theupgrade in the last two years, panelists encour-aged upgrade managers to construct moredetailed time schedules. “A refined schedule,”suggested panelist Gary Sanders, “will supportpossible requests for additional manpower andfunding.” Gunther Haller, reporting on thetrigger system, said the Fermilab group shouldprepare detailed system diagrams, as well, tohelp refine cost estimates. Several panelists rec-ommended that managers establish more mile-stones, especially for the first few months of1999. As the chief project manager, JimChristenson hastened to respond to the impliedcriticism: “I think milestones are wonderful,”he assured the panel. “We always intended tohave them.”

Chairman Dan Lehman concluded thecloseout session by reiterating one of the mainissues: “It’s manpower—you told us that’s theissue the first day, and we agree.” Fermilab par-ticipants thanked the DOE panel for theirwork. Christenson appeared to speak for manywhen he volunteered, “I for one have profitedfrom this exercise.” Fermilab’s Deputy DirectorKen Stanfield emphasized that the reviews are important to establish a joint sense of commitment. ■

William Griffing began his duties as thenew head of Fermilab’s Environment, Safetyand Health Section on April 29, replacingActing Head Larry Coulson, who resumed, full time, his position as assistant director.Griffing previously managed ES&H func-tions at the National Renewable EnergyLaboratory in Golden, Colorado, where heserved for seven years.

Griffing said he welcomes the opportu-nity to help scientists resolve ES&H issues ina research environment and has taken on thechallenge of gaining an in-depth under-standing of forefront particle physics researchas practiced at Fermilab. He said his goal isto make safety an integral part of ongoingplanning and decision making at theLaboratory. The image of ES&H as a set ofrules and regulations may still persist atFermilab, as at other Department of EnergyLaboratories, he said.

“Enforcement and control are not theproper approach to safety,” Griffing declared.Rather, he hopes that “by the time I leaveFermilab, the image of ES&H will simply beavoiding injury. I care about people. I wantto use my skills to help people avoid gettinghurt. There is no reason for anyone to gethurt at Fermilab.”

Griffing based his decision to come toFermilab partly on the Laboratory’s 1995participation in the “Necessary andSufficient” pilot program. Fermilab staffworked with the Department of Energy andothers to devise the simplest effective list ofES&H requirements to operate theLaboratory safely. “Not only had Fermilabgone through the process,” he said, “butthey had modified the contract” to incorpo-rate the N & S provisions. He now continuesthe process of implementing the new provi-sions within the Laboratory’s existing ES&H bureaucracy.

“We will be a customer-service organiza-tion,” Griffing said of the 95-person ES&HSection, adding that he will consult staff members in all areas of the Laboratory toseek views on how the section can serveFermilab better. ■

SitewideEmergencyWarningSystem

How do Fermilabemployees know if theweather service hasissued a tornadowarning, or if an off-site emergency affectsFermilab? By June 30,ES&H’s EmergencyManagementDepartment expects to implement a newsystem for issuing suchalerts. According toEMD Head RomeshSood, the SitewideEmergency WarningSystem (SEWS) consistsof existing communica-tion systems and newlyinstalled EmergencyAlert Receivers andSafety Alert Monitorunits. BuildingManagers, EmergencyFloor Wardens, orSenior Safety Officerscan provide more infor-mation on the opera-tion of the SEWS. EMDwill conduct tests ofthe components duringthe week of May 27,and a full-functionaltest on Tuesday, June 4,at 10 a.m. The testschedule of systemcomponents is as follows: 113 pagers,daily at 9:30 a.m.; outdoor warning sirensystem, the firstTuesday of each monthat 10 a.m.; DZero, CDF,FCC Horns, EmergencyAlert Receiver andSafety Alert Monitor,the first Tuesday of Julyand April; Wilson HallHorns, Sundays at 3a.m. in April andOctober.

components for the upcoming fixed-target run.The difference between their responsibilities,says Roger Dixon, head of the ResearchDivision, is that the Research Division tends todo the “heavy” work building and commis-sioning beamlines, while the Physics Section,which is smaller, designs and builds activedetector components and electronics. TheResearch Division also specializes in designingcustom electronics for specific applications.

Stephen Pordes, deputy head of the PhysicsDepartment, has crossed several major items offhis section’s to-do list in recent days. For E831,he said, the Physics Department recently deliv-ered two new wire chambers. “We’ve just deliv-ered the segemented-wire ion chamber forE815 and fixed the last of broken wires in theirwire chambers.” At KTeV, Pordes continued,“we are delivering the last digital readoutboards for the photomultiplier tubes, we arejust finishing the low-voltage power supplies,and we are feverishly fixing the last bases for thephotomultiplier tubes themselves, among otherprojects.” Pordes must now turn his attentionto urgent electronics work for E831.

Bruce Baller, associate head of operationsfor fixed-target in the Research Division, saysmembers of his division are working to fulfillobligations described in Memoranda ofUnderstanding with each of the experiments.“The Research Division will provide a beam,mechanical, electrical and electronic support fordetectors,” he says. “My charge is to coordinatethese preparations within the division.” Anexample of Research Division assignments is thechamber gas system: “Experiments use a gasmixture in their detectors,” says Baller. “Argon-ethane is sort of the ‘Fermilab gas.’ In the past,experimenters would assemble their own gas-mixing systems—they might use ethane frombottles out of the stockroom. In the last fixed-target run, the quality of gas from the suppliersuffered, and the efficiency of the chamberswent to pot; several experiments were off-linefor several weeks.” For the upcoming run, saysBaller, the mechanical support section isinstalling standard gas-mixing stations and largeethane tube trailers, which will improve thequality control of the gas.

The Research Division also replaced aleaking vacuum pipe buried 20 feet under-ground. “A 300-foot section [between theSwitchyard and Proton area] was dug up andreplaced,” says Baller. “In the last fixed-target

run [four years ago], corrosion caused water toleak into the pipe, forming an ice ball, creatinga loss point in the beamline.” Baller pauses andadds, “One tends to forget how many miles ofvacuum pipe there are that need to be leak-checked and rebuilt.... It’s fair to say there’s oforder 1,000 devices that have to be checked;for radiation safety, there are about 100 items,and we have 40 enclosure interlocks, a systemof doors and gates underground, that need tobe secured for safety.”

One of the people involved in radiationsafety is the Research Division’s Bill Higgins. Heexplains that his task is to help answer the ques-tion, “Is our shielding adequate?” The beamconditions will be different this time, he says,because of higher intensity in the accelerator.“We use information about how thick the soil is,from the Fermilab alignment group, and wherethe walls are, from architectural drawings,” saysHiggins. “If there is not enough shielding, weput a fence up, or request for more soil to beadded. Then we ask the alignment group to goout and survey the area again.”

As the countdown to the fixed-target runcontinues, members of the upgrade staff in alldivisions are exhibiting varying levels of confi-dence and anxiety. At the weekly All-Experi-menter’s Meeting on May 20, Director JohnPeoples seemed reassured by Pordes’ presenta-tion of the Physics Section’s list of remainingjob requests. “You can see to the end of thefixed-target preparations then?” asked Peoples,almost rhetorically. “We’ve been seeing that fora while,” rejoined Pordes. Several audiencemembers contributed the unsolicited commen-tary that “The light at the end of the tunnel isthe headlamp of an oncoming train.”

KTeV, The Origins of CP Violationin the Kaon System

In March, FermiNews reported that KTeVexperimenters had tested the first crystalinstalled in the lower left corner of the cesiumiodide calorimeter. Since then, members of theKTeV team have been laying the crystal ele-ments row by row, and connecting them totheir power supply and read-out electronics.Now, as of May 20, “about half of the array isin,” says Project Manager Greg Bock. The fourdrift chambers are installed, and have been ‘readout’ to test them. Similarly the trigger andmuon counters are in, and being read out. Bockcontinues, “The transition radiation detectors

are being installed—eight of nine are in. Thebeamline is in the final stages of assembly; thereare five or six more weeks of work on that.”What’s the overall picture? “We’re gettingeverything to work,” says Bock.

Experiment 862, The Productionof Antihydrogen

Experiment 862 declares itself on schedulefor beginning the fixed target run. The goal ofthe 12-person collaboration, which includes sci-entists from Fermilab, the University ofCalifornia at Irvine, and Pennsylvania StateUniversity, is to produce and detect atoms ofantihydrogen.

The Accelerator Division has finishedE862’s requested modifications to theAntiproton Accumulator, including installationof Y-shaped beam pipe in a bend dipole andmoving and reinstalling two acceleration cavi-ties. The gas-jet and antiproton source onwhich E862 depends for its target are up andrunning.

Members of the collaboration have tunedthe positron spectrometer, and it is nearly readyfor survey onto the beamline. The accompa-nying positron detectors are undergoing final

testing and installation. The bend dipoles forthe antiproton spectrometer have beeninstalled, and its small wire chambers are under-going minor maintenance before installation onthe beamline.

Experimenters have tested and installedmost of the time-of-flight counters they willuse. In the counting room, cabling is nearly fin-ished, as is final hookup of the trigger and dataacquisition systems. Accelerator Division staffhave worked with experimenters to completeaccelerator controls work on the foil targetwheel and magnet controls. The ComputingDivision recently delivered a workstation, nowbeing fitted with peripherals and software, foronline monitoring. “Since our expected datarate is very low, and our number of channels issmall, we haven’t had to worry about con-structing a sophisticated system for data acquisi-tion,” said Irvine graduate student GlennBlanford. “All in all, we are excited to startseeing antihydrogen atoms.”

Experiment 815, NuTeVExperiment 815 held its Beginning-of-Runparty on Saturday, May 18. It might seem likejumping the gun, but the collaboration beganrunning shifts on Monday, May 20, and “wefigured we should celebrate while we still hadtime,” said collaborator Janet Conrad, ofColumbia University. E815 asked theAccelerator Division to deliver 150 GeV beamover Memorial Day Weekend. Experimentersplanned to use the 150 GeV beam to alignE815’s beamline magnets to an accuracy of 30thousandths of an inch, in preparation for theactual run at 800 GeV.

The 40-member collaboration will use abeam of neutrinos to make precision measure-ments of neutral current interactions, providinga test of our understanding of aspects of theStandard Model. E815 will also measure therho parameter, equal to one in the StandardModel. If the experiment finds a deviation fromone in this parameter, the finding would sug-gest new physics beyond the Standard Model.

When the run begins, E815 will use a fastspill of the beam from the accelerator. Becauseneutrinos interact so rarely, the experimentneeds the fast delivery of many particles atonce, to distinguish the beam signal fromcosmic ray background.

Experiment cospokesman Bob Bernstein ofFermilab said “We’ll be ready by Friday, May24. Our detector works. We are now surveyingthings into place and making the final powerand water connections.”

“Things are under control,” Conradagreed, ticking off the list of tasks she and her

collaborators had completed in recent weeks.She said that while she always enjoys prepara-tion for a new experimental run, she findsworking on E815 especially satisfying. “Ourexperiment is different from others,” she said.“We all get along really well.”

E872, Search for Tau NeutrinoExperiment 872 is the direct search for the

tau neutrino. Researchers hope to find the par-ticle and better understand its properties. Sincethe discovery of the top quark, UC DavisPhysicist Vittorio Paolone, cospokesman forE872, said news reports often state that scien-tists have observed all of the fundamental parti-cles in the Standard Model.

“It’s just not true,” he said. “There is a lotof indirect evidence, but [the tau neutrino] hasnever been directly observed, like the electronand muon neutrinos.”

Byron Lundberg, the other cospokesmanfor the study, said the experiment’s construc-tion proceeded a bit slowly until mid-May, buthas progressed at a faster pace since. Becausethe experiment was approved later than someof the other studies, E872 was forced to waitfor resources, including engineering support,technical support and riggers, among othernecessities. During the last half of May andearly June, workers will be setting up the hard-ware for the study, including a magnet and tonsof steel shielding. The coils for the experimentalmagnet are presently in California being refur-bished.

Despite the amount of work thatresearchers still need to complete, some com-ponents are already in place. Collaboratorsfrom Japan recently installed the fiber trackingsystem for the study, a task that took nearlyfour weeks. The drift chambers are alsoinstalled.

As he watched Paolone pull cable for thedata acquisition system recently, Lundberg saidit will be a challenge to be ready by earlyAugust, and he looks forward to the day theteam can turn their attention to taking data.

E868, Search for Antiproton Decay

E868, known as the APEX experiment,is an anomaly for Fermilab. It is neither afixed-target experiment nor a collider experi-ment. Although it is grouped with the fixed-target experiments set to begin this summer,E868 has already finished taking data and isin the analysis phase. Further the experimentcomprises only 14 researchers, rather thanthe large collaborations more typical ofFermilab.

APEX is a search for antiproton decay,and ran at the Antiproton Accumulatorfrom April to June in 1995 during Run Ibcollider operations. Although the experi-ment is small, its goals are ambitious: toimprove on the sensitivity of previoussearches for antiproton decay by a factor of1,000, and to test a fundamental theoremin high-energy physics that requires thatantiparticles (e.g. antiprotons) live just aslong as their particle cousins (in this case,protons). Observation of antiproton decayswith lifetimes less than their proton counter-parts “would be revolutionary,”said SteveGeer, the experiment’s spokesman and aFermilab physicist.

Researchers have some preliminaryresults, and Geer expects to have moreresults by the end of this year. He said hethought E868 was grouped with the fixed-target run for organizational reasons.

When asked if he enjoys working withthe smaller collaboration, Geer smiled andsaid, “It’s fantastic!”

The team includes researchers fromFermilab and the University of Michigan,Pennsylvania State University, UCLA and the University of Nebraska. ■

Fermilab recently implemented a newhuman resources payroll system that takesadvantage of new software and hardware tech-nologies, resulting in a more efficient pay distri-bution process.

The new integrated system is less cus-tomized than the old method, making it easierfor Fermilab to upgrade and alter as needed.Although most employees will not notice theincreased speed in the process, they can expect anew paycheck and stub design, as well as someslight differences in calculations of benefits.

Out With The Old...The old payroll system, called Integrel or

ISI, ran off an IBM mainframe and “has seenbetter days,” said Lynne Lazarski, HR systemsadministrator.

The machine often crashed, resulting intime-consuming delays in the payment process.The ISI also had many customized features,making it harder to adapt to new ideas or cor-rect problems. Lazarski said ISI was also check-ered with “bandaids,” or repairs that addresseda host of very specific problems and not thesystem as a whole. Lastly, the Business Officeand Laboratory Services wanted to take advan-tage of new client server technology that has thepotential to expand to other functions.

...In With The NewThe new software, purchased from

Peoplesoft, is an integrated system, allowingPayroll and Personnel staff to work with onedatabase. For example, “applicant tracking” isnow integrated with the human resourcessystem. In the past, when a person applied for ajob at Fermilab, employees in the EmploymentOffice would enter the applicant’s informationinto the system. If the prospect was hired,Human Resources staff would have to reenterthe information into another data base. Thenew system allows Laboratory workers to savetime by updating only one file. The newPeoplesoft software is also less customized,allowing the Lab to upgrade the system aschanges are needed and new requirements arise.

“It’s a very powerful machine...that defi-nitely saves time,” said Lazarski.

The new design of Fermilab’s paychecks andstubs, complete with moredetailed information.

Laboratory Adopts More Efficient Payroll SystemNew technology is more flexible, while making paychecks and stubs more informative

A New LookThe new pay stub is easier to read and has

more detail in its presentations. Health-planenrollments, specific charities, after-tax deduc-tions and before-tax deductions all are listedseparately. Each employee’s home address willalso appear on the check.

Along with the newdesign, employeesmay see some differ-ences in the actualnumbers. Forexample, someemployees’ voluntarypension contributionsmay change slightlybecause the new soft-ware calculates years ofservice more accurately,using the actual date ofservice and not just the year of service as thestarting point.

Some employees whohave Supplemental LifeInsurance may find a differ-ence of $1,000 in their cov-erage and related deductionamounts, which can be attrib-uted to different methods ofrounding. The deduction dif-ference for $1,000 more in coverage is about 39 cents per month.

Weekly employees received the new checksand stubs with their May 3 pay, and monthlyemployees’ paychecks changed beginning withthe May 31 payment.

Payroll and Benefits staff were pleasantlysurprised to receive a minimal number of phonecalls from weekly employees confused about thechanges, and they hope monthly personnel willadjust as smoothly. The payroll upgrade is partof more sweeping reforms in the Business Officeand Laboratory Services, which a futureFermiNews article will address.

Gell-Mann,author of The Quark and the Jaguar, won theNobel Prize in physics for his work on thetheory of elementary particles. His recentresearch at the Santa Fe Institute focuses oncomplex adaptive systems. Tickets $5. 8 p.m.Ramsey Auditorium, call (708) 840-ARTS forinformation and reservations.

him to stay in touch with ever-growing collaborations.

Although it is quite time-consuming,Swallow said he continues with the teaching-research balance at the small school because hecan involve undergraduates in his work atFermilab. In some of the earlier CP violationexperiments, Elmhurst students helped buildand test the lead glass monitoring and calibra-tion system. Anthony Kowalczyk, one of thestudents who worked on the lead glass, went onto get a Ph.D. in physics at Case WesternReserve University. More recently, MichaelCallahan, one of Swallow’s students, workedwith a Fermilab postdoc on the monitoringsystem for the cesium iodide calorimeter thatexperimenters will use in the KTeV study.

A few Elmhurst College graduates havemoved on to important work at Fermilab. StanOrr, leader of the Power Systems Group; JamesVolk, a staff physicist and Kenneth Hartman, anexperimental area operator, all work in theResearch Division and all did their undergrad-uate work at Elmhurst College.

Consolato Gattuso, an Accelerator operatorand another Elmhurst graduate, said Swallowtaught nearly all of his upper level courses.

“Some of my fondest memories ofElmhurst College involve work on the particleaccelerator with Dr. Swallow,” said Gattuso.“The thrill of being able to use what we learnedin class in a hands-on environment...was whatDr. Earl Swallow was all about. He was able tohelp us understand, and put to use, the materialthat we learned—and for that I’m grateful.” ■

I enjoyed your article on the “Take YourDaughters and Sons to Work Day” at Fermilab(FermiNews, May 17, 1996), and I was espe-cially pleased to see the picture of John Foster,one of the Education Office Docents. I doneed to correct your caption. John and all ofour Docents (we currently have 15) are notvolunteers. They are paid, part-time Fermilabemployees who facilitate student field trips andother program-based activities for theEducation Office. Thanks for recognizing Johnand his colleagues. They do an excellent job ofincreasing scientific literacy and providing apositive Fermilab image to the general public.
