The University has decided to permanentlyextend the annual Winter Shutdown from oneweek to two. A full two week shutdown willnow become the norm for the entireUniversity for the foreseeable future.

The original objective in closing the Universitywas budget savings. There has been asurprising amount of positive feedback frompeople throughout campus.

In addition to institutionalizing the shutdown,there will be two additional paid days off in2004 to assist employees in maintaining fullpay during the shutdown; in all future years,there will be one paid day off granted.

The Laboratory is abuzz with activity. Like the blossoming of spring these past few weeks, SLAC’s scienceprogram is in a period of tremendous evolution and productivity. The range of activities is broad, including:construction projects like the Gamma Ray Large Area Telescope (GLAST) and the Linac Coherent LightSource (LCLS), the development of exciting new theoretical ideas in particle physics, major R&D programslike the Next Linear Collider (NLC) and the Enriched Xenon Observatory (EXO), the development of newdirections and instruments for particle astrophysics, and new approaches to meet the enormous challengeswe face in computing, to name but a few. In addition to these exciting developments for our future, we are ofcourse vigorously operating our accelerator facilities for the roughly 3,000 users world-wide who do theirresearch at SLAC. In this month’s column I would like to update you on the operating facilities.

SPEAR3 is doing science! The first synchrotron light was brought into beamline 9 on March 8, and users are now back at work, signaling a new era ofsynchrotron radiation experimentation at SLAC. SPEAR3 will operate at 100mA during this first year, while beam-line components are upgraded inpreparation for full 500-mA operation next year. This has been an exemplaryproject that has set standards of competence that will be hard to match.SPEAR3 was built on time, commissioned on time, has performed beautifullyfrom the start and of course, was on budget. We promised that SPEAR3 wouldbe ready for users in March and here they are! Everyone who contributed tothis Laboratory-wide project should feel justifiably proud of their achievement.

The B Factory, too, is bursting with new developments and achievements. Anew mode of operation started on March 11, called the ‘dual trickle injection’mode, which injects new bunches of particles continuously into both theelectron and positron rings. Previously, BABAR datataking had to be suspendedabout once every 40 minutes while the storage ring currents were topped upto their maximum operating point. Trickle feed means that BABAR can take data

virtually uninterrupted with both beams at full operating current, leading to a significantly larger number ofevents logged per day. New performance standards were set at the B Factory in March with record PEP-IIpeak luminosity, record data collected, both in one shift and in one day. PEP-II is the only accelerator in theworld using this new technique of ‘dual trickle injection’, maintaining SLAC’s tradition of acceleratorinnovations. Don’t miss the article on the front page of this TIP that explains this development in more

detail. Congratulations to the fabulous PEP-II team that made this breakthrough happen, and also to theBABAR folks who adjusted their detector data-acquisition to conform to this very challenging mode ofoperation.

The primary electron beam, besides being used for injection into PEP-II, is also currently the backbone of theFinal Focus Test Facility (FFTB), whose running hours are shared between the high energy physics programand the synchrotron light program. FFTB is capable of delivering the shortest pulses in the world, either a) inthe form of the electrons directly or b) after conversion in an undulator magnet, in the form of x-rays. Inrecent months the running time has been shared between the x-ray experiment SPPS and the E-164collaboration which is doing advanced accelerator R&D.

The E-157, E-162 and E-164 collaborations (SLAC, UCLA and USC) have been studying the use of plasmasfor future high-energy accelerators. Plasmas have the potential to provide acceleration rates much greaterthan those obtained using conventional technology. Data from E-162 experiments have already shown peakacceleration on the order of 200 MeV per meter, which is very exciting when compared to our linac’s averageof 17 MeV per meter. The E-164 and E-164X experiments finished their latest FFTB run during which theywere working toward attaining ultrahigh peak acceleration of up to 10 GeV per meter. At a recent meeting inWashington, DC, they showed preliminary results of accelerations in excess of 1 GeV per meter.

SPPS, a nine institution, three-nation collaboration, is breaking new ground in the use of ultra-fast pulses tostudy a wide range of otherwise inaccessible material properties. Given that this ultra-short pulse ofsynchrotron radiation is novel, much of what they are doing involves the development of new detectionstrategies. SPPS has already detected the arrival time and width of the electron beam in the FFTB withsubpicosecond (a millionth of a millionth of a second) resolution and will work on developing similartechniques for the x-ray beam. They have also focused the x-ray beam to a spot more than 100 timessmaller than a human hair. The combination of these developments will be exploited in the coming year tostudy how materials behave when exposed to peak x-ray power, approaching what is expected from theLCLS.

It is the Laboratory staff’s professionalism, dedication and their strong identification for the success of ourmission that has enabled the current growth and change in so many sectors of the laboratory.

In December 2003, Pierre Schwob of Palo Alto endowed the Kavli Institute for Particle Astrophysics andCosmology (KIPAC) and the Fred Kavli Building project with a $1 million donation for the foundation of the P.R. Schwob Computing and Information Center. The center will be housed on the second floor of the FredKavli Building and will include an interaction and collaboration area, a reading room, a video-conferenceroom and two visualization studios.

“I have always been fascinated by the mysteries of our cosmos,”says Schwob, “and I am very happy to be able to make acontribution to furthering our understanding of thesefundamental questions. One can say that cosmology is becomingan exact science and, as the instruments used to probe theuniverse and its history now gather such immense data sets, Ihave an interest in helping the development of the resources tostore, analyze, visualize and share information.”

Schwob is a software engineer. He owns several patents and is aWorld Wide Web pioneer. In 1994 he started the Classical MusicArchives, the largest collection of classical music files on thenet. He is the author of an anthology of historical documents, abook on chess openings and a book on pocket calculators.

The Schwob Center plans include a ‘hyperwall’ for thelarge-scale visualizations crucial to astrophysics, and advanced

graphics machines. The conference room will have stateof-the-art audio-visual equipment allowing on-lineparticipation in international collaborations. The reading room will be devoted primarily to electronicresources for researchers.

“We at KIPAC are thrilled by Pierre’s generous gift,” said KIPAC Director Roger Blandford. Not only is heproviding a focal point for the data-and simulationintensive research we will be carrying out, but he is alsotaking an active interest in how we equip and use it.”

Founded last March by physicist and philanthropist Fred Kavli, KIPAC is bringing together the traditions ofastronomy, cosmology and particle physics—fields whose advancement is increasingly and inextricably linked.

No one gets hurt. That’s what we would all like to have happen at SLAC. But people are getting hurt, at ahigher rate than any other DOE Science Laboratory. Because injuries don’t happen every day, we tend toignore their presence until they affect us personally. And even though many injuries we see in the workplacecan be fixed or cured, some have the potential for long-lasting detriment to your health and lifestyle. A smallaccident or injury now can lead to much greater pain and disadvantage in the future.

Here at SLAC we need to work together to reduce the number offuture accidents that occur. In fact we aim to reduce accidentsand injuries by 20 percent in the next year, as a first steptoward getting down to a lower baseline level. This is not to saythat any level of accident or injury is acceptable. By theirnature, accidents are unpredictable, but we can take steps toreduce the chances of them happening. We need to aim for zeroaccidents and zero injuries.

What can you do to reduce your own personal risk of injury?First, and most important, identify and control the hazards inyour workplace. This means ensuring that you are current withall necessary safety training, can identify the hazards in yourworkplace and follow the safe work practices required for yourown work circumstances, use the proper materials or tools forall jobs, and allow sufficient space to perform all tasks.

What is SLAC doing to help? Our Lab-wide ES&H efforts are focusing on accident reduction. The AssociateDirector of your division and other management staff will work with you to identify what can be done toenhance safety within the division as well as what you can do to enhance your own safety. This year’s Talk,Walk program is centered on accident reduction. You’ll be hearing more from us with simple ideas forreducing your risks.

No one gets hurt. That’s our aim and we want to help you make your workplace safer now for the benefit ofyour future well-being.

Toxic and carcinogenic chromate has contaminated the groundwater in Hanford, Washington, one of theunfortunate legacies of producing plutonium for nuclear weapons. At times, plumes of contaminatedgroundwater have reached the Columbia River, posing a risk to spawning salmon.

Existing technologies, such as pump-and-treat, are largelyineffective for mitigating chromate in the groundwater at thislocation due to the large volume (millions of gallons) and depthof the contaminant plumes.

Recent research conducted at SSRL and at the Pacific NorthwestNational Lab (PNNL) has shown that naturally occurringsediments at the Hanford site are immobilizing some of thechromate. John Zachara (PNNL) and Gordon Brown and JeffreyCatalano (both of Stanford University), tested contaminated andhighly radioactive soil samples at SSRL to determine thechemical forms of the chromate—carcinogenic hexavalentchromium or the less toxic trivalent chromium—and theirrelative amounts.

They used X-ray Absorption Spectroscopy, which makesdistinctive patterns that act like fingerprints to identify differentchemical forms. Hanford had previously used hexavalentchromium in the industrial process to recover plutonium fromirradiated nuclear fuels. The resulting high-level waste corrodedits storage tanks and leaked into the desert subsoils at Hanford.

About 42 percent of the chromate in the contaminant plumeshad become an immobile solid that contained trivalentchromium. Researchers said that the solid forms whenhexavalent chromium reacts with iron-bearing sediments in theaquifer. Solid trivalent chromium is unlikely to dissolve—andthus is effectively taken out of circulation in the groundwater.

“It’s a great synergy,” said John Bargar (SSRL), the molecular environmental scientist who runs the beamline where the tests were conducted. “The sediment-hosted ferrous iron prefers to transfer its electrons tooxidized species such as chromate. The resulting ferric iron and trivalent chromium want to precipitatetogether into a mineral. Once present in solid form, chromium can’t flow in the groundwater, and it’s veryslow to dissolve or won’t dissolve. As a result of these reactions, about half of the problem is abated.”

Unfortunately, more than half of the chromium in the plumes remains as the more toxic hexavalent form,which moves readily through the subsurface sediments. However, the team’s discovery is a necessary andhuge step toward mitigating the problem, Bargar stated. Zachara’s study is one of many ongoing studies atSSRL looking at contaminated sediments from Hanford. Developing technical solutions to such largescalecontaminant problems requires key insights into the form of the contaminant. This information allowsengineers to assess the hazards posed by such extreme chemical and radioactive materials, and to designthe most effective, long-term strategies to deal with them.

Rapid, reliable data transport is essential for global scientific collaborations to gain new knowledge. SLAC wasrecently honored for its contributions to highspeed networked computing.

Data are nature’s gift to scientists, but the giftcan at times feel like a curse. To address somekey questions in their fields, researchers at thefrontiers of particle physics, astronomy,bioinformatics, global climate modeling andseismology need to harvest, store, share andanalyze staggering quantities of information.

Today, the BABAR collaboration ships about aterabyte of data every 24 hours between SLACand computing centers in France, Italy, andEngland—the equivalent of a thousand copies ofthe Encyclopedia Britannica a day. To continue tomake scientific breakthroughs, their datasetneeds to roughly double every year.

By the year 2010, when a new generation ofexperiments will be underway, the high energyphysics community anticipates that datasets willreach 100 petabytes, the digital equivalent of20,000 times all the text in the Library ofCongress. Thousands of physicists and students atinstitutions around the world will want to accessand process them using petaflops of distributedcomputing. (A petabyte is 1 billion megabytes; apetaflop is 1 million billion computations persecond.)

The computing tools to provide these capabilitiesare being developed by the leaders inhigh-performance computing at SLAC and their

colleagues around the world.

Teams of physicists from Caltech, SLAC, LANL, CERN, Fermilab, Florida International University, University ofFlorida, University of Michigan, BNL, and the MIT Haystack Observatory are focused on optimizing the use ofthe Grid for data-intensive science. The Information Grid is analogous to the electric power grid. Just as youtoast your bagel in blissful ignorance of which power generators your toaster is drawing electricity from,you’ll analyze data using a geographically distributed network of computational resources, without everknowing where they are.

The collaboration, which also includes experts from U.S. industry, is building a permanent facility for testing,tuning and using applications from physics and astronomy that require reliable data transfers at rates of upto 10 gigabits per second.

The partnership is named UltraLight because data are transmitted as pulses of light. A single optical fiber cantransmit information at 10 gigabits per second using one frequency. By using different wavelengths, thatsame fiber can carry more than 100 different signals simultaneously.

Networking knowledge, experience and innovations from the UltraLight partnership will also be invaluable fordeveloping the gigabit state-wide network being built to serve millions of Californians. These contributionswere recognized last month by CENIC, a not-for-profit corporation dedicated to facilitating advanced networkservices for research and education in California. Ultralight won CENIC’s second annual ‘On the Road to aGigabit’ Award, announced in March, for “the best use of highperformance networking developed by aprivate/public partnership.”

UltraLight is building on an earlier triumph. At the Supercomputing 2003 conference: a team from SLAC,Caltech, LANL, CERN, Manchester and Amsterdam, with assistance from private industry, set a world recordfor fastest data transmission last November: 6.6 terabytes in 48 minutes, a rate of 23.2 gigabits per second(see TIP, Dec. 12, 2003). This is the equivalent of about 2,000 featurelength DVD-quality movies. The goalwas to demonstrate what can be achieved with technologies that are readily available today.

“We wanted to open people’s eyes,” said SCS Assistant Director Les Cottrell, “and get them thinking, ‘Whatwould I do if I had this [capability]?’”

“The way you move data shapes the design of experiments,” says Cottrell. “Until the late 1990’s, most highenergy physics data were transferred on tapes. At SLAC alone, producing, packaging and shipping the tapestook the full-time effort of two people.” How long did it take for data from SLAC to reach a researcher atCERN? Two weeks.

In a broader context, Cottrell believes the team’s results will stimulate scientists and engineers in otherareas to invent new models for collaboration in research and business. People around the world will be ableto share their computing resources and information with unprecedented ease and efficiency.

PEP-II reached a new milestone on March 11 by phasing in trickle injection, a mode of operation whichincreases the production of B and B-bar particles by up to 50 percent. With the new technique, the BABAR

detector can keep taking data virtually uninterrupted while the linear accelerator (linac) injects electronsand positrons into the two PEP-II storage rings.

“I think it’s a great improvement, and it should lead to much better performance,” said John Seeman (AD).

Up to 1,400 bunches of particles circle around PEP-II’s storage rings at any given time—electrons in the highenergy (9 GeV) ring and positrons in the low energy ring (3.1 GeV). The linac periodically injects morebunches to replace those that are used up in collisions in the BABAR detector.

In the old mode, BABAR had to be switched off every 45 to 90 minutes to allow for a five-minute ‘top-off’procedure to inject new bunches. With trickle feed, new bunches are injected continuously at a rate of up to10 bunches per second. Initially the highly energetic newcomers push the other bunches around, thusincreasing the amount of experimental error, or background. Researchers learned how to quickly teach theexuberant bunches to stay in line, so that within just one millisecond BABAR can get reliable data again.

After more than a year of testing, trickle injection was introduced in the low energy ring last December,bringing the B Factory a 30 percent increase in output. With the highenergy ring joining in this month, anadditional 15 percent increase is expected.

“This was meant to be a two-day test,” says BABAR Run Coordinator Steve Playfer (Edinburgh U), “but it wentwell, so we decided to keep it going. The experiment has been running at its peak luminosity.”

The advantages go beyond the numbers according to Playfer. Continuous injection makes the storage ofparticles more stable, so the PEP-II rings are easier to operate. “Once you’ve done this mode,” says Playfer,“you don’t want to go back.”

The success of trickle injection is the result of a close collaboration between the BABAR and PEP-II teams.Chris O’Grady, Amedeo Perazzo and Matt Weaver (all REG) modified BABAR’s data acquisition system to sendfeedback to the accelerator and the storage rings. Thanks to better detection along the particles’ path, Franz-Joseph Decker, Richard Iverson and Jim Turner (all AD) finely tuned the timing of the injection system.

On March 29, the SCS Windows Infrastructure Group started to roll out a new Citrix XPe farm to replace theold Citrix Metaframe 1.8 farm. For those of you not familiar with theSLAC Citrix farm, it provides:

• A secure way to gain access to a full Windows desktop set up with the SLAC environment (e.g., with accessto SLAC network drives) from onsite or off-site. Your local drives and printers can also be accessed from thisdesktop.

• An easy way to access heavily-used applications such as Microsoft Office. The Citrix farm is the preferredmethod to check e-mail from offsite via Microsoft Outlook.

• A convenient way for Unix users to access Windows resources. Once installed, the Citrixenvironment can be accessed from a Windows platform via the Web (http://slaccitrix1.slac.stanford.edu orhttp://slaccitrix2.slac.stanford.edu). Access for supported Unix platforms are made using the Citrix clientdirectly.

The new Citrix farm is encrypted through Secure Socket Layer (SSL), a protocol more likely to be availableat remote sites. On Unix platforms configuration is necessary to support SSL (see on-line documentation).

The old Citrix farm will be shutdown on May 3. Current Citrix farm users will be contacted by wts-admin withinstructions on how to switch to the new Citrix farm. You will be able to use both farms as you transition tothe new farm.

A new Web interface from which users can install applications, the Xweb, has replaced the X drive. Users willnow access the Xweb to install SLAC supported applications instead of the X drive.

The impetus to migrate from the X drive to the Xweb is to meet vendor and DOE requirements for trackingusage of licensed software and to notify users of licensing terms. Installations of software from the Xweb willbe logged. When users leave SLAC they will receive a reminder to un-install the software from non-SLACcomputers. Software on SLAC computers will be taken care of by local administrators. Since the Xweb is aweb interface, it is more intuitive and user-friendly than the X drive, and installation instructions are moreclearly written.

The Xweb Web site is currently only accessible within the SLAC internal network. To install software bring upan Internet Explorer browser and type in the Xweb Web site. You will be presented with a sortable selectionof software available for installation.

If you would like to contact the maintainer of the application or review application requirements, select theapplication link. Once you have selected the software, you will be asked to accept SLAC Software LicensingTerms. Upon agreeing you will be able to install the applicable software. If a license number is necessary toinstall the software, it will be found on the page following the acceptance of the SLAC Software LicensingTerms. Installation of some applications on the Xweb may require administrative privileges on your laptop ordesktop.

As indicated in the recent Director’s All Hands memo, accidents have been on the rise. In 2003 theLaboratory experienced 33 accidents, compared to 19 in 2002.

Responding to this increase in accidents, the Laboratory is planning an Accident Reduction Talk and WalkStanddown. Since 1996, SLAC has conducted many annual Talk, Walk, and Clean (TWC) Standdownscoordinated by the Safety and Environmental Discussion Assistance Committee (SEDAC). The purpose ofthese Standdowns was to assess and remedy the most pressing safety and environmental issues. Thistradition was interrupted last year by a review of SLAC’s safety programs against OSHA and DOErequirements in preparation for our recent OSHA costing visit.

This year the more traditional Standdown will return, focusing on reducing accidents with the resulting lostand restricted work time. As in previous years, operations will cease during the Standdown. The accelerator,and critical processes in other areas, will go into an appropriate stand-by condition. All members of theLaboratory will be assigned to small teams organized by division.

Each team will select one of two methods for conducting this year’s Standdown:

1. Talk—a meeting in which ideas for reducing accidents and related lost and restricted time are discussed,the two most important issues are identified, and corrections within the control of the team are suggested

2. Walk—a walk-through inspection in which facility conditions relevant to reducing accidents are identifiedfor corrective action

The Clean component of the earlier TWC standdowns will not be conducted this year because a similar taskwas performed in preparation for the OSHA visit that occurred this February.

A number of tools will be made available to teams to facilitate the standdown process. These include:

• An Accident Avoidance Analysis Tool that provides ideas from safety professionals for typical approaches topreventing accidents, based on actual SLAC incidents

• A Job Hazard Analysis Tool that can be used to prevent accidents

Three little pigs, three bears, three wishes. In storytelling, significant things often come in threes. So it iswith worker safety. This spring you’ll be hearing more about three new systems for improving workplacesafety:

1. The routine Job Hazard Analysis and Mitigation(JHAM) for day-today tasks2. The non-routine JHAM for new, unfamiliaractivities3. The Area Hazard Analysis

In turn each of these systems relies simply onyou asking these three questions:

1. What are the job steps, tasks, or equipment?2. What are the hazards associated with the task(or area)?3. How do I mitigate each hazard? For MoreInformation

The University has decided to permanently extend the annual Winter Shutdown from one week to two. A fulltwo week shutdown will now become the norm for the entire University for the foreseeable future.

The original objective in closing the University was budget savings. There has been a surprising amount ofpositive feedback from people throughout campus.

In addition to institutionalizing the shutdown, there will be two additional paid days off in 2004 to assistemployees in maintaining full pay during the shutdown; in all future years, there will be one paid day offgranted.

This year SLAC will be shutdown on Saturday, December 18 and will renew work again on Monday, January3, 2005—except for some special projects. In the Fall, when science program decisions have been finalized,more details will be communicated.

SLAC will follow its past practice of allowing staff who have insufficient time to cover the mandatory days offto borrow from their 2005 Personal Time Off days, their Floating holiday, and, if necessary, from theirJanuary 2005 vacation accrual.

New E-mail Infrastructure

Over the past few months, we have been replacing the old software running on most of our e-mail gatewayswith new software that can scan e-mail for viruses and spam. We expect the replacement to be completed inthe near future.We no longer deliver e-mails found to contain a virus but still deliver emails which are unscannable. Thesemessages will arrive with a warning that the server could not scan the e-mail. You should not open thee-mail unless you were expecting it. An example of an unscannable attachment is a password-protected Zipfile.

We also plan a feature to hold suspected spam on the server. You would receive an e-mail digest on a regularbasis (daily/weekly) listing all undeliverable e-mails held as spam. You would click on links in the digestmessage to retrieve any messages. Otherwise, spam messages will be purged from the system a�er a fewweeks. You can configure the purged date to meet your requirements. We will provide more information asthese new features become available.

Exchange 2003

We have been configuring and testing Exchange 2003 servers. The Exchange 2003 servers are connected toa Storage Area Network (SAN), which should provide us with sufficient storage for our growing amounts ofe-mail. The SAN also provides redundancy and fail-over access to the hard drives where our e-mail is stored.

The testing has been going fairly well but we are proceeding cautiously. At this time, we are looking atmoving all of the SLAC Exchange users to the new servers in May.

We will provide more information next month on what to expect during and after your e-mail is moved toExchange 2003.

Pictured are participants at the Geant4 tutorial course held at SLAC on March 8-10. The tutorial wasconducted by instructors from SLAC, aimed at novice and middle level users of the Geant4 simulation toolkit.The classes consisted of lectures, hands-on tryouts and open discussions. Geant4 is a toolkit that simulates

the passage of particles through matter. It is used in diverse applications, including simulation of high energyand nuclear physics experiments, radiation shielding, space radiation transport and effects, and medical

physics. SLAC has been actively involved in its development and user support since the launch of the project.
