As SLAC DJit#onnathan Dorfannoted in hide speech, "Thisday is dedictf6&tothe SLAC staff asa celebration of tiaccomplishmentsand contributifis to science made bythem."

The count ofthose contributionswould now have to include the eventitself. The affair, which involvedmonths of tireless planning andpreparations by over 100 people, wentoff smoothly and without a majorhitch.

"I am so grateful to the SLAC stafffor their support of this event," said40th CommitteeMember Pat Kreitz(TIS). IIWhenever- at member of theCommitteewent-to someone for helpor put out a -ad for vohmteers, peoplepitched right-in<. ltasimspiring towitness howrmuch everyone cared tohelp makethis a special celebration."

SLAC staff contributed in manyways, including program planningand implementation, AV, graphics,disabled transport system, parties andcatering, to mention just a few. Therewere over 80 SLAC staff volunteershelping on the day of the celebration.

In his closing speech, Dorfan wasquick to recognize the many peoplethat contributed to the event. "Thiscelebration could not have happenedwere it not for the super-human effortof a highly motivated group of ourstaff who organized this extravaganzaas volunteers."

For the afternoon event, SLAC staff,government representatives, guestsand scientists streamed to a giantwhite tent erected on the Green.

There, in addition to speeches byDorfan, the afternoon includedspeeches by Stanford President JohnHennessy, Peter Rosen from theDOE Office of Science, University ofToronto President Robert Birgeneau,Davidson Institute of ScienceEducation Chair Haim Harari, andformer SLAC Directors Burton Richterand Pief Panofsky. In the day's mostpoignant moment, Panofsky received

a standing ovation as he walkedonstage to address the audience.

Before leading the audience to areception on the "Green," Dorfanspoke about SLAC's bright future,touching on work done across theLab. "The achievements of the first 40years will be difficult to top," he said,"but the ingredients are already inplace to make the next 40 years just asmemorable."

Later in the evening Jack Marburger,Chief Science Advisor to PresidentBush and Director, Office of Scienceand Technology Policy, delivered thekeynote address at a dinner held atStanford's Alumni Center.

In his remarks, Marburger quotedfrom poet T.S. Eliot's Four Quartets toillustrate his vision for the future offundamental science:

We shall not cease from explorationAnd the end of all our exploringWill be to arrive where we startedAnd know the placefor thefirst time.

"The truths that poetry evokes arewithin ourselves," Marburger said."Within the experiences that lie in ourmemories and are drawn out by theirresonances with the propositions ofthe rhythmic lines.

SLAC's ElectronBeam GetsAstrophysical

By Miriam Boon

In 1916, Victor Hess risked his life toobserve cosmic radiation by ridinga balloon up to 17,500 feet withoutoxygen. Since then, scientists havebeen puzzled as to where high-energycosmic rays come from and how theygot accelerated to nearly the speed oflight.

The mystery recently deepenedwhen scientists noticed a discrepancybetween the results of leadingexperiments that use differenttechniques to study ultra high-energycosmic rays (UHECRs).

One of these experimental groups, theUniversity of Utah's High ResolutionFly's Eye (HiRes), has been workinghard to determine the source of thisdiscrepancy. Their investigations havemost recently led them to collaboratewith the High Energy LaboratoryAstrophysics (HELA) program hereat SLAC, a new initiative led byPisin Chen (ARD-A) and aimed atsimulating astrophysical processesin the laboratory so that they can bestudied at closer quarters.

Together, the two groups hope tonot only shed some light on thisnew inconsistency, but also to gain adeeper understanding of how high-energy cosmic ray air showers behave.

Unraveling the High-Energy CosmicRay Mystery

We know that cosmic rays have awide range of energies, beginning atthe low end of high-energy physics.UHECRs stand apart from other high-energy cosmic rays because they canin principle be tracked to their originby observing their trajectories. Thisis possible because their momentumis so great that, even if they carrycharges, they are not deflectedsignificantly by the magnetic fieldsthey encounter as they travel throughspace.

Unfortunately, they are also veryrare. At an energy of one hundred-billion-billion electron volts-twobillion times greater than the highestenergy particle SLAC's acceleratorcan achieve, and the highest energycosmic ray observed to date-onlyone such UHECR can hit a squarekilometer on Earth per century, and

there is no way of predicting wherethese rays will hit. High-energycosmic rays do, however, causesomething called an 'air shower.' Asingle high-energy cosmic ray canresult in an air shower that is visibleto detectors using air fluorescencetechnique from tens of kilometersaway.

Upon entering the atmosphere, anUHECR would initially decay intohadrons, which shortly thereaftercascade into leptons, such as electrons.The air shower's effect is similar toan avalanche's progress--the moreparticles there are in the shower, themore interactions occur and the moreshowering particles result. By thetime the shower reaches the groundthe final particles are much lower inenergy and have been spread wide.

Detecting the air showers

Our atmosphere contains mostlynitrogen molecules. The high-energyleptons in an air shower interact withthe electrons that are attached to thosenitrogen molecules, imparting energyto them. This causes the nitrogenelectrons to temporarily orbit furtherfrom the molecule's nucleus.

As the electrons eventually return totheir normal orbits, they emit photonsin the ultraviolet range. This is whatscientists called "air fluorescence," thesame physical mechanism that makesfluorescent light bulbs work (but atdifferent frequencies). Observing thisfluorescence is useful in determiningthe initial energy of the UHECR, andis used by HiRes to detect high-energycosmic rays.

Unlike HiRes, another leadingexperiment called the Akeno Giant AirShower Array (AGASA) counts thenumber of shower particles that reachthe earth. It compensates for the rarityof UHECRs by covering a large areawith detectors of a different kind.

the experiments' resolutions weregood enough for them to see thediscrepancy between their results.

Joining Forces, Taking action

This unsettling discovery spurredChen and Pierre Sokolsky, of theUniversity of Utah and HiRes, tojoin forces. Together, with a teamof scientists, they are attemptingto confirm or correct the existingcalibrations of air fluorescencetechnique by using SLAC's electronbeam to trigger and simulate airshowers. Additionally, they hope togain a better understanding of high-energy cosmic ray showers by crosschecking the results of laboratorymeasurements against pre-existingcomputer simulations.

This improved calibration of the airfluorescence will help determine if it isinaccurate calibrations that have led tothe mysterious discrepancy betweenHiRes and AGASA's results.

Study of the simulations used toimprove the calibration will alsohelp scientists to better understandair showers. Chen commented, "Itis a happy coincidence that the totalenergy of a typical SLAC beam isroughly equivalent to that of thehighest energy cosmic ray observed todate."

The information gained willbenefit not only the existing HiResexperiment, but also the nextgeneration Pierre Auger Observatory,currently under construction inArgentina, as well as the next-nextgeneration space based observatoriessuch as the joint U.S.-European EUSOand the U.S.-lead OWL projects.

Said Sokolsky, "We're going to be ableto make a very good measurement atSLAC. This is exciting. SLAC is justperfect for this." *

ErgonomicsProgramThrives at SLACBy Miriam Boon

You may have noticed that the pink-tagged bicycles around the Lab havedisappeared. They were removedfor good reason: the Safeguardsand Security Department (SSD) hasbegun an ongoing program in whichabandoned bicycles will be collectedto be recycled or, where possible,refurbished.

When former Medical DirectorMargaret Deanesly called for someoneto look into the treatment andprevention of Repetitive Stress Injuries(RSI), a condition caused by repeatedmovements such as typing, nurseGloria Labrador volunteered to lookinto it. Nine years later, Labrador hasbuilt a successful ergonomics programat SLAC-from the ground up.

Celebration. Some of the bicycles hadbeen left untouched for years. SSDbegan collecting the bicycles in lateAugust. Three bikes were claimedby the Transportation Department,where Alfonso Manuel (SEM) isreconditioning them so that they canbe reused around the Lab.

Two of the refurbished bicycles will beavailable for use by SLAC employees.To request the use of a reconditionedbicycle, anyone can fill out a servicerequest form, and if one is available itwill be issued at that time.

Sewer SafetyBenefits You andthe Environment

By Michael Hug

One of the incidents mentioned inthe recent Safety Stand Down was ablocked sewer line that resulted in therelease of sewage into the storm drainsystem.

The release occurred on August 2, atthe construction site for the new GuestHouse. The sanitary sewer line wasblocked with rocks, paper towels andcloth rags.

This is a friendly reminder to folks atSLAC of the environmental damagethat non-biodegradable products cancause if flushed away.

The careless disposal of items likecloth shop rags, paper towels, andrubber gloves can block the sanitarysewer and increase SLAC's operationand maintenance costs. Theseitems complicate the treatmentof sewage and they can even getthrough wastewater systems intothe environment. This costs theenvironment and can spoil the beautyof our coastline.

How can I make a difference?

Don't flush personal items at all.Anything that is not biodegradableshould be put in the trash. Specificallyanything containing plastic, but alsolatex products, sanitary napkins andeven tissue!

You might be surprised to learn thattissue shouldn't be put in your toiletbecause it is not designed to breakdown like toilet paper. Also, don'tdispose of gasoline, oil, antifreezeor other hazardous solvents andmaterials into the sewer system. Theseitems can cause serious injuries toUtility Workers and cause damage to

Used bicycles get a new lease on life.

The remaining ten bikes were passedon to Alan Conrad (PRC), who ismaking arrangements to sell the bikesto SLAC staff.

"How and when the bikes will besold has not been finalized, althoughwe're shooting for early November,"said Conrad. "Any money raised fromthese sales would go to SERA, theSLAC Emergency Relief Association."O

Sewage spills can be a very noticeablegushing of water from a manhole, ora slow water leak that may take timeto be noticed. Don't dismiss wet areasthat cannot be accounted for.

Look for:

* Drain backups inside the building

* Wet ground and water leakingaround manhole lids on your street

* Seeping water from cleanouts,outside drains

* Unusual odorous wet areas:sidewalks, external walls, grounds/landscape

Please, use the sewer system for whatis was designed to accommodate.Having a sewage backup is not apleasant experience.

of Michigan, Labrador returned toSLAC armed with the knowledge tofight RSI. She set up a program thatpro-actively screens staff for RSI, andhelps them set up a work environmentthat is ergonomically correct.

"Since we started the ergonomicsprogram, we have decreased RSIclaims by 90 percent," Labrador said."I think we have a very good programover all. The success of the programwas the result of the Lab being willingto provide the right equipment, and ofemployee compliance."

Pro-Active Treatment

In 1997, a form called "PhysicalRequirement and ExposuresChecklist" was revised to includeergonomics. If it shows that a newemployee's job puts her or him indanger of RSI, Labrador will contactthe new hire about making anergonomic appointment.

"We have gone pro-active," she saysemphatically. Approximately fiftypercent of the employees who arecontacted by Labrador respond, and

Even though computers are morepervasive than ever at SLAC, theinstance of RSI has surprisingly notincreased over time. "To the contrary,"Labrador explains, "because peopleare more aware, at the first sign theycome to the Medical Department" fortreatment.

Labrador is preparing to leave SLACthis month to start a new ergonomicsprogram at a Bay Area computer chipfirm. Once she leaves, John Turek(SHA), who has also been doingergonomic evaluations for the last fiveyears, will continue in this capacity.

A replacement for Labrador hasnot yet been chosen, but ergonomicappointments are still available byrequest.
