ADMIRAL WATKINS ATTENDS TECHNOLOGY EXPO

Secretary of Energy, Admiral James D. Watkins, and Nina Stolar of SLAC at SLAC'sexhibit for the National Technology Initiative (NTI). The NTI was a series of showssponsored by the Department of Energy, Commerce, Transportation, NASA, and theEnvironmental Protection Agency intended to get industry from many areas aroundthe country in contact with government laboratories to explore ways to transfertechnology from laboratory use to commercial products. SLAC participated in theSanta Clara Convention Center show hosted by Stanford University. These showsoffered DOE labs a means to show what they do and encourage industry to tap thesetechnologies for possible commercial applications. SLAC's booth featured theaccelerator and SSRL and several technologies including klystrons, silicon detec-tors, and synchrotron radiation analytic tools that may be of commercial interest.

THE SEASON FOR GIVINGRECENTLY, 77 PEOPLE from the SLAC community helped to fill the local

blood reservoirs that supply Stanford Hospital, Packard Children's

Hospital, and various Palo Alto clinics. Because donations have been

running low lately, the need for blood right now is pronounced. This

medical community uses about 28,000 units in a given year, making the

Stanford University Blood Bank the second largest transfusion service in

the country. So as you can see, the 77 people who donated at SLAC gave a

much-needed gift. And, for those of you who want to donate again (or for

the first time) blood donations will be held on Tuesday, December 22,

from 9 a.m. to 4 p.m. in the auditorium lobby. To make an appointment,

call Pauline Wethington, ext. 2204.According to Barbara Adamo at the Stanford Bank only five percent of

the eligible population donates blood, and a person can safely donate

every 56 days, or about six times a year without a problem. As Adamo

says, "Give of yourself; they can't make a substitute for blood yet."-Trevor Payne

Welcome Bjdrn Wiik

FAMILIAR FRIENDLY FACE RETURNS (AGAIN)by Trevor Payne

BJORN WIIK IS BACK at SLAC,and he's happy. The hadronelectron ring accelerator heworked on at DESY over the lasttwenty years is coming to life. Andhis success has been repaid, asWiik comes to SLAC the heirapparent to the directorship ofDESY. This is quite a feather in hiscap, although he views the ap-pointment as somewhat dubious.Wiik said "Yah, I'm pretty close,"to accepting the position, but notbefore "a lot of commiseration."

The challenge of running DESYis something that is important toWiik, and personal. "There is acertain sense of responsibility," hesaid in his affable and understatedmanner. "Somebody has got to runthe place, and I have a strongfeeling of what should be done."

Wiik is also aware of the addedpressures the inclement economicclimate will provide, as the formerwellspring of dollars is somewhatshallower than it has been. Indeed,part of what he is doing at SLAC isthinking about the next generationof linear accelerators, and howhigh-energy physics will be able toextend itself into the next century:"It's really a difficult situation forphysics right now, so it's impor-tant to see the laboratory into thefuture," Wiik commented.

The custom of massive nationalspending on duplicate machinesand technology "is a tradition thathas served us well [to date], butone that will have to change," hesaid. Wiik's words are very wellsupported in practice by HERA.The collider was not only broughtto life by international expertise,but international funding as well.Foreign contributions eventuallycovered about 15% of the costs,making this is one of the mostwidespread international physicsefforts of its kind, including

countries from North America,Europe, and East Asia.

Internationalism is nothing newto Wiik. His route from Norway'scraggy west coast to big physicstook him across many borders.After high school, Wiik attended asmall technical university inGermany, and then from Germanyto California. Ironically, if it hadn'tbeen for a poor high school per-formance, he might not have evenmade it to Germany. Fortunately,the culture shock of his sojourn atschool was tempered by beingaccompanied by many of hiscontemporaries-all with badgrades. Wiik explained that it wascommon for Norwegians to leavetheir country to study.

In Germany Wiik fed his pen-chant for physics. During theseyears his interest was encouragedby a high school teacher and a for-tuitous summer job in the sciencedivision of a Norwegian researchinstitute where he was exposed toresearch on nuclear reactors.

In 1964 Wiik came to SLAC afterhaving been recruited to Stanford'sHanson lab while he wascompleting his Ph.D. It was here

his intimate connection to accel-erators and particle physics began.

Once in California, Wiik foundhimself involved in a variety ofprojects. Among other things, Wiikworked with Perry Wilson, wherehe was introduced to acceleratorphysics, and dabbled at SLACworking with Dave Ritson. In1972, after experiencing a broadrange of physics, Wiik left for theUniversity of Hamburg withvisions of HERA in his head.

HERA follows up on workwhich was done at SLAC duringhis stay here. It was during thistime that the proton's internalquark structure was discovered bya collaboration that includedSLAC's Richard Taylor. Since then,the inside of the proton has beenmuch better understood; this newmachine should increase the detail.

"What you're doing [withHERA] is probing the inside of theproton," Wiik said. "And whatyou get with this machine is amuch larger kinematic range thanbefore." This means that muchhigher energies can be used toprobe than those previously used.According to Wiik, not only canphysicists see the proton better, themore powerful accelerator willpossibly push physics in a wholenew direction. "One thing thatHERA is particularly well-suitedfor," he said, "is to find a new kindof particle."

Some theorists suggest theexistence of an independent hybridparticle, combining traits from thetwo already-known classesprovided for in the currentStandard Model, the leptons andthe quarks: "Some people believethere are also quantum numberswhich combine the two-theleptoquark," Wiik said. Thiswould be a whole new class ofmassive particles.

Harris Leads San Jose All Stars to World ChampionshipA WORLD SERIES BASEBALLchampionship-albeit not of thevariety won by the Toronto BlueJays-was nonetheless savored byMechanical Fabrication Depart-ment supervisor Bryan Harris. Heand the San Jose All Stars bested afield of 145 entrants from aroundthe world to win the 1992 Men'sSenior Baseball League (MSBL)World Series recently concluded inTempe/Mesa, Arizona.

Harris, the starting pitcher in acritical third-round game againstthe Denver All Stars, gave up sixhits and a single unearned runover seven innings en route to an8-6 victory that kept San Jose'shopes alive in the championshiptournament. The San Jose All Stars,selected from throughout thePeninsula and Santa Clara Valley,went on to post victories over all-star entries from Los Angeles,Long Island, South Dakota,Chicago, and the Former SovietUnion. The championship victory,a 14-4 thumping of the San DiegoAll Stars, was made sweeter com-ing over a squad that had beatenthem 5-9 in an earlier round. Thetitle game was carried nationwideon ESPN TV and taped for delayedbroadcast in Europe, the formerSoviet Union, and the Far East.

Bryan Harris is all smiles as he sports aSan Jose All Star jacket. Affixed to theright side of his jacket are two medal-lions given to him by a member of theformer Soviet Union squad that com-peted in the recently concluded worldchampionships won by the San Joseentry.

Not to be confused with themany levels of recreational base-ball flourishing throughout thecountry, MSBL is a seriously com-petitive brand of ball, with eachteam (particularly all-star squads)liberally laced with former majorleaguers, AAA performers eitherascending or descending the majorleague farm system, and a varietyof semi-professional athletes. TheMSBL World Series is played onfacilities maintained by the various

major league teams for theirannual spring training programs.

This past season marked Harris'third season in San Jose MSBL, a20-team field, and his secondstraight selection to the all-starsquad. A right-handed pitcherwith a "wicked knuckle curve"(according to opposing batters)and a good fast ball and slider,Harris closed the past season witha nine-win and four-loss record.

Harris also competed in thesoftball national championship in1988 and 1989, and was voted tothe all-tournament team at thestate softball championships in1988. An avid snow and waterskier, the versatile employee is alsoa commercially licensed pilot whoserved two years with theSan Mateo Sheriff's Air Squadron.

Serving as player/manager ofthe SLAC softball team for each ofhis 14 years here, Harris remindshis fellow employees that SLACsoftball is supported primarilyfrom revenue realized through thesale of logo jackets and other SLACclothing and paraphernalia duringthe annual Christmas sale now inprogress, and he urges anyoneinterested in participating insoftball to contact him.
