It's been a loasime comin'. SPEAR2,named SPE)N~vhen it was builtmore than Wars ago, will closedown on Mi@31. But, it won't bea long time ge. In an enterprisingexample of close-order scheduling,the upgrade to SPEAR3 will beginjust two hours-after the eventmarking SPEAR's closing.

SPEAR2 is the venerable physicsworkhorse that enabled a significantpercentage of the spectacularscience for which SSRL and SLAChave become world-renowned. It isarguably one of the most productiveresearch facilities ever built.

The Stanford Positron ElectronAsymmetric Ring (SPEAR) firstoperated in 1972 for high energyphysics (HEP) research. Of the manyhigh-energy experiments that wereconducted, two have led to NobelPrizes. The first experiments withsynchrotron radiation began at

Compact LightSource GoesCommercialStaff Forms New Companyto Develop TabletopSynchrotron Light Source

By Torn Mead

A spin-off enterprise based on SLACtechnology transfer has emerged. Anew company has been formed todevelop a compact synchrotron lightsource based on Compton scatteringof a laser beam. The founders of thecompany are Ron Ruth (ARDA),Rod Loewen (KLY), and Jeff Rifkin(formerly with ARDA). The NationalInstitutes of Health is funding theprototype development.

The enterprise is named LynceanTechnologies, Inc. Lyncean refersto the eye of the lynx, historicallyused as a metaphor for acute andpenetrating vision. The name isapt; Lyncean intends to develop andmarket a tabletop light source, whichhas imaging capabilities comparableto a modern synchrotron lightsource. This represents an effectivescale reduction of 200:1 over existing

M synchrotron light sources.

How it Works

The Compact Light Source (CLS)builds on the SLAC and SSRLexperilence with large synchrotrons.Existing synchrotron light sourcesat U.S. facilities employ multi-GeVelectron beams stored in large ringsof magnets to generate intense,bright 0.1 nm wavelength radiation.The CLS uses a marriage of anelectron beam and laser beam toaccomplish the same effect. Theshift from the periodic magnets(undulators or wigglers) of thetypical synchrotron light source, tothe laser beam in the CLS, allows a

SLAC physicists call science, notbusiness, their specialty. But SLACdoes not exist in a vacuum, and whenhardware and software developedto support specialized research findwider audiences in industry, relationswith the private sector can prove veryuseful. Coordinating SLAC's interestswith commercial interests-withoutgetting in the way of science -is thespecialty of the Office of TechnologyTransfer (OTT).

The OTT, a four-person group withboth technical knowledge andbusiness savvy, operates in SLAC'sBusiness Services Division. The officedrives the recognition, protectionand transfer of laboratory-developedtechnologies with commercialpotential, and spends much of its timearranging and managing technicalcollaborations involving SLACprojects and private companies.

SPEAR3: Standing on the Shoulders of a Giant

Radiation Shielding Experiments .-at the FFTB 1-0 !

S . j. -, L ,n,By Miriam Boon

A team of radiation physicistsrecently completed a series ofexperiments at SLAC to determinethe high-energy neutron spectra andits attenuation length in concrete.These are important quantities in thedesign of shielding at high-energyaccelerators.

"We want to be conservative in ourapproach to radiation safety but needto be as accurate as possible in orderto save in the cost of shielding," saidSayed Rokni, of the Radiation PhysicsDepartment (RP) at SLAC.

Rokni and Takashi Nakamuraof Tohoku University havebeen leading a collaboration ofphysicists from CERN and theirrespective institutions in a seriesof experiments to reach a more

accurate understanding of the energyspectrum of neutrons as they passthrough shielding.

Measurements of this precision hadnot been possible to date, due to thelack of accurate calibrations of high-energy neutron detectors. The finalcalibrations of the NE213 organicliquid scintillator, which made theexperiment possible, were carried outin 2001 by Tohoku University.

Nakamura's group first used quasi-monoenergetic neutron beams toraise the calibration range to 200 MeVfrom the original 20 MeV. Then, atthe Heavy Ion Medical Accelerator inChiba, they used neutrons generatedin the interaction of heavy ions ona thick carbon target to extend therange up to 800 MeV. A time-of-flighttechnique was used to determine theneutron energies.

crucial in the ability to performthese measurements. Ted Fieguth(EFD), Clive Field (EB), Ron Seefred(OHP) and Accelerator DepartmentOperations staff were instrumentalto the successful completion of themeasurements.

The experiments were conductedby aiming the beam at the FFTB'saluminum beam dump. The resultingbremstrahlung radiation interactswith nuclei, causing neutrons to beemitted. The neutrons and remaininggamma rays pass through iron andconcrete shielding, losing energy.

At the edge of the shielding, a Bonnermulti-sphere detector set measuresthe neutrons with energies lowerthan 20 MeV, and the NE213 detectormeasures neutrons with energies

from 6 MeV to 800 MeV. Shieldingwidth was varied as data was taken.

This is the first time that the neutronspectra have been measured in sucha wide range of energy through theshielding of a high-energy electronaccelerator.

Results are expected in spring of2003, and will be used to benchmarkshielding calculations in particleaccelerators.

identify items that might be useful forindustry. "What we build here is forour own purposes. \We have to defineits commercial use, put togetherdocuments and apply for a patent,"Simpson said. Typically, the OTTsingles out for development roughlya half-dozen technologies that itconsiders commercially promising.

Technology transfer is not simplyaltruism on the part of SLAC. WhenSLAC technologies are protectedand licensed, the lab and inventorsgain compensation and royalties. Inaddition, the OTT has helped SLACscientists and engineers win DOEgrants and industrial support todevelop their technologies.

Collaborating With the PrivateSector

Much of the OTT's work involvesarranging collaborations withprivate companies to co-developpromising technologies. "We leverageSLAC resources for research anddevelopment," Simpson said. Theagreements serve the commoninterests of SLAC and industry andmake use of the complementaryresources of SLAC and the industrialpartners, usually small businesses."It's not a one-way street," Simpsonsaid.

By helping private companiescoordinate their own work withSLAC's technical projects, the OTTgives private companies access toSLAC technology and brings both

private innovation and fundinginto SLAC. "For an investment ofa half million dollars spread over ahandful of projects and two or threeyears, SLAC is able to obtain fromthese collaborations research anddevelopment results worth 10 or15 times as much," Simpson said.Collaborative R&D projects for 2002were valued at nearly $2.5 million,but OTT Associate Patrick Lui seesother important reasons for thiscooperation. "There is the intangiblebenefit of being able to importtechnology," he said. "There is thepossibility of new inventions."

The OTT staff use their broadbase of experience to deal withtechnological, legal and business-related elements of their cases. "It's areally interesting mix of problems tosolve. It's necessary to understand thetechnology thoroughly- the physicalprinciples," said Lui.

Expert in SLAC's technologies,the OTT functions as a liaison tothe business community and U.S.government, but also deals in-housewith large portions of commercialnegotiation and legal protocol. SaidMurphy, who like his colleaguesjoined the office from a physicsbackground, "It's a much morehuman and complicated negotiationatmosphere than I expected."

Developed in the 1980s

SLAC first codified its goal oftechnology transfer in the 1980s-theOTT took on its present name androle in 1990. According to Simpson,the combination of U.S. industrialrivalry with Japan in the 1980s and

the Cold War's close in the early1990s pushed the DOE to increasinglyfocus its resources toward civilianapplications.

A sequence of legislation-includingthe 1980 Stevenson-WydlerTechnology Innovation and Bavh-Dole Acts and the 1989 NationalCompetitiveness Technology TransferAct-provided legal infrastructure fortechnology transfer and collaborationwith the private sector, leading to theopening of similar offices throughoutfederal labs.

Electron Gamma Shower

Of a number of technologies theOTT has ushered into industrialdevelopment, Lui has beenparticularly involved in the transferof a revolutionary software program,Electron Gamma Shower (EGS), firstreleased in 1978 by SLAC physicistRalph Nelson and a colleague atStanford, and later improved at lowenergies by colleagues at the NationalResearch Council of Canada.

The EGS software, which models thedissipation of energy produced ashigh-energy electrons and photonsenter various media, found a perfectniche in the radiation therapyindustry. Since its introduction,numerous companies have integratedEGS into cancer treatment systemsor relied on it as the 'gold standard'against which to test their ownsoftware.

Over the course of several hard-fought years, the OTT helped Nelson,along with an international groupof collaborators, secure product

protection, substantial DOE grantmoney and commercial licensing fornewer versions of EGS, includingthe EGS 5 system currently underdevelopment. "What is gratifying isthat we are a national lab, and ourjob is to do fundamental research,"Nelson said. "If, in the process, wecan make a contribution to society,that's great."

Creating an Entrepreneurial Culture

According to Murphy, the cultureat SLAC, where specialized sciencetakes the front seat, is inherentlyless entrepreneurial than the cultureof Stanford University, wheretechnology transfer is endemic. Inspite of that, said Murphy, "[TheSLAC environment] is slowlychanging."

According to Lui, DOE effortsin recent years to streamlinebureaucratic elements of technologytransfer as well as research programslike Stanford's inter-disciplinary Bio-Xenterprise, which may take a footholdat SLAC, should further encouragetechnology transfer at SLAC.

Looking ahead, said Lui, "I find itmost exciting to see the possibilitythat something we do that is soesoteric may find commercialapplication, sometimes in areasbeyond our wildest dreams."

Several years ago, John Turek, ES&HSafety Engineer, introduced behavior-based safety at SLAC. [See Behavior-Based Safety Process Underway inthe July 2001 issue of TIP.]

The Site Engineering andMaintenance Department (SEM)has been using the Safety TowardsAvoiding Risk Today (START)process since that time. The purposeof behavioral based safety training isto reduce the probability of injuriesby: observing work practices for bothsafe and at-risk behaviors, talkingwith workers about performing jobsin a safer manner, and asking forinput to improve safety.

Since 1999, the START process hasmade improvements to safety withinSEM, as noted by David Toews,Facilitator of the START SteeringCommittee. "Workers are performingmore safe behaviors than at-riskbehaviors," he said. "This is broughtupon by workers being more awareof safe activities while performingtheir jobs." Workers feel the processis a worthwhile investment, andthey are willing to work together tochange unsafe areas and practices.Another improvement has been thatcommunication between workers andsupervisors has improved.

There are more 'Level 3' observationsby peers who are trained Observers.Level 3 observations ensure there istwo-way communication betweenthe observer and worker. The bestobservation is one in which theworker provides feedback. Therewere over 500 observations in 2002,up from 355 the previous year. Hasthis made a difference in safety?"Yes," said Toews.

Toews asked workers in SEM to seewhat they thought of the behavior

based process, and if they thought ithad made a positive impact on theworking environment. A few of thecomments he received are:

* George Sandoval, Lead Painter:"Any safety process that keepsemployees from getting injured isgood."

* Daniel Manley-Arrieta, UtilityMechanic: "I noticed that our safetyawareness has improved from threeyears ago. We plan our jobs betternow than we did in 1998."

* Ron Pacheco, Service Mechanic: "Isee workers becoming more awareof safe activities. Having otheremployees remind us of the safeactivities we are doing and the At-Risk activities we need to improve onis a good way of keeping us on ourtoes."

* Eddie McGee, Health PhysicsTechnician: "The process has been areal good thing. The process keepsus all reminded that safety is first. Inotice working habits are changing."

* Jose Regalado, High VoltageTechnician: "Personally I am moreconscious of my actions at work andat home, and the process has madethis impact in my life."

Toews has been the Facilitator of theSTART program since June 2001 inSEM; Lorenzo Lowery will take overthe Facilitator role in April. 0

reduction of energy and scale by afactor of 200. The CLS is so small thatit can easily fit on a typical SLACconference table.

Why

During the past 30 years,synchrotron light sources havebecome the x-ray probe of choicefor materials scientists, physicists,chemists, biologists and researchphysicians. With their high-quality, intense x-ray beams,these large research facilities havespawned a large number of newtechnologies spanning a broadarray of applications. Ratherthan having to go to a facility likeSSRL, miniaturization will allowresearchers to use the CLS at theirown site.

Ruth, who is taking a part-timeleave from SLAC to get the companylaunched, said, "We need tominiaturize both the machine andthe cost of ownership. In terms oftechnology transfer and dispersion,this is a way of bringing to thehealth community, the biologycommunity, and to society some ofthe very specialized knowledge andtechnologies produced at SLAC overthe past 40 years." 0

I want to inform you of another visitto the Bay Area by the TravelingResource Center associated with theEnergy Employees OccupationalIllness Compensation Program Act(EEOICPA).

SLAC and DOE wish to notify youthat you may be eligible for thisimportant Federal benefits programand how you can apply or get moreinformation.

As a reminder of this program,during the Cold War workersemployed in the nation's atomicweapons program or otherprograms may have been exposed toradioactive and toxic substances. In2000, Congress passed The EnergyEmployees Occupational IllnessCompensation Program Act toprovide assistance to those workerswho have become ill as a resultof employment at atomic weaponfacilities or other facilities.

Individuals, or their eligiblesurvivors, who were an employee,contractor or subcontractor at aDepartment of Energy (DOE) facility,such as SLAC, may be eligible forbenefits under this Program.

Program Administered by theDepartment of Labor

The federal portion of the EEOICI'A,administered by the Department ofLabor (DOL), was enacted to providecompensation to workers withcancer, beryllium disease or silicosis.Employees, or their survivors, whoseclaims are approved may receivea lump-sum payment of $150,000and medical benefits for the coveredillness.

Program Administered by theDepartment of Energy

DOE has established independentphysician panels of occupationalmedicine doctors to review whether

workplace toxic exposures mayhave caused or contributed to DOEworkers' occupational illnesses. Ifthere is an affirmative finding, DOEwill assist the worker in filing a claimwith the state workers' compensationprogram.

Toxic-related illnesses could include:asbestosis, liver disease, nervoussystem disorders, non-cancerousrespiratory or kidney disease, heavymetal poisoning, certain reproductivedisorders or other diseases.
