B FACTORY OFF TO GREAT START

by Sarah Morisseau

SLAC IS A-BUZZ with prepara-tions for the B Factory, not theleast of which is the recent deci-sion to make PEP-II a formal divi-sion of SLAC.

Director Burton Richterannounced the decision in a Feb-ruary 17 memo to the directorate.Jonathan Dorfan, project managerof the B Factory, is now the Associ-ate Director of PEP-II. "It is myintention that this organization

structure will persist through thecommissioning phase of the pro-ject (one to two years after turn-on) at which time the organizationwill be restructured," Richter saidin the memo. The PEP-II DetectorProject is a part of the ResearchDivision, which David Leithdirects.

The memo also states that an"interlaboratory coordinatingcommittee" has been establishedto keep the directors of SLAC,Lawrence Berkeley Laboratory,

and Lawrence Livermore NationalLaboratory informed of the B Fac-tory's progress. Dorfan (or hisdesignee), Bill Barletta of LBL, andTony Chargin of LLNL are mem-bers of the committee.

"We're off to a great start,"Dorfan says. "The three labs areworking very well together on themachine, and the detector collabo-ration looks good, too."

Currently, there are eight na-tions participating in the detector

LIBRARY, PUBLICATIONS ENTER NEW ERADURING THE LAST YEAR itwas hard for most of us to imaginethat anything good could comeout of the cancellation of the SSC.But the demise of the Texas parti-cle physics lab has provided SLACwith the skills of many extraordi-nary physicists, engineers, andprofessional staff. One of these isPat Kreitz, who has quickly as-sumed her new responsibilities asManager of the SLAC Library andPublications Office. She is de-lighted to be joining two impres-sive departments that are stronglyservice oriented.

Pat brings to SLAC a breadthand depth of professional experi-ence. Since 1989, as Manager ofLibrary and Information Servicesat the SSC, she has concentrated onbuilding, with her staff, a state-of-the-art research library. The valueof the services provided wasreflected in use statistics that dou-bled yearly, even when controlledfor annual population growth.

Although recently a resident ofthe Lone Star State, Pat is nostranger to the Bay Area. From

1979-1989, Pat worked at the UCBerkeley Library. Initially a Refer-ence Librarian, she rose quickly tobecome Head of General Refer-ence Services for the graduatelibrary. Pat's on-the-job experi-ences are complemented by anactive role in professional activi-ties within regional consortia andthe American Libraries Associa-tion. Additionally, Pat's educa-tional background includesgraduate degrees from the UCBerkeley School of Library andInformation Studies and from theUC Davis Department of History.

Currently, the SLAC Library isone of the world's leaders in pro-viding electronic access to HEPpreprints. The Publications Officeis making some exciting innova-tions in electronic informationdelivery as well. One of Pat's twoprimary goals will be to ensurethat her staff have the resourcesthey need to continue to improveelectronic access. A second chal-lenge she faces is to look at users'needs within the life cycle ofSLAC's scholarly and institutional

collaboration: Canada, China, France, Germany, Italy, Russia, the UnitedKingdom, and the United States. Dorfan speculates that more countrieswill join in June, when the 200-page letter of intent from the collaborationis due. A final engineering proposal will be submitted to the lab by theend of the year.

The third meeting of the collaboration will take place in Paris at theend of March. Collaboration meetings are held every six weeks where theparticipating physicists consolidate the work they are each doing sepa-rately.

President Clinton's budget proposal for FY95 includes $44 million forthe B Factory. Because the B Factory was awarded $36 million this year,Clinton's proposal would give the project 45 percent of its total funding injust two years. "If it holds up in Congress, we'll be in great shape," Dorfansays.

A building is being constructed to house the key people of the project; it willbe placed in a yet-undecided location by the end of the summer. Themagnets from the old PEP ring are being dismantled, and the tunnelshould be cleaned out in nine months or a year.

Teachers Visit ExploratoriumTHE SAN FRANCISCO Explora-torium was the site of a follow upmeeting for teachers who partici-pated in SLAC's Particles andInteractions workshop last sum-mer. Twice during the academicyear, teachers from past work-shops gather to share lesson plans,ideas for hands-on activities, andresource information pertaining toteaching physics in high schools orcommunity colleges.

On this occasion teachers hadthe Exploratorium to themselves,and played with exhibits beforethe museum officially opened. Lat-er in the day they participated indiscussions about classroom appli-cations. Teachers enjoyed theopportunity to talk with SLACphysicists Helen Quinn, WillyLangeveld, and Marvin Weinstein.Exploratorium Director ThomasHumprey gave a presentation onthe strengths of interactions, usingbeta decay as an example.

ON MARCH 6 BILL ASH DIED after a brief,intense struggle with cancer. At a memorial service inPief's Grove on March 12 Bill's family, colleagues, andfriends spoke of the ways Bill touched their lives.

Bill headed the group that built the superconduct-ing final focus for the SLD, having earlier managed thecontract with the firm in Japan that built the sole-noidal coil for this large detector. He came to SLAC in1972 to work on the polarized target for the spin-structure experiments in End Station A. In 1976 hejoined the group that built and ran the SLAC side ofthe MAC detector at the PEP storage ring. He served aseditor of the Beam Line from 1982 to 1985 and pub-lished newsletters for PEP, SLC, and SLD.Marty Breidenbach remembers:

Bill was my closest colleague and friend at SLAC.We spent a lot of time in each other's office, and therewill be no one like him at SLAC.

Bill had a unique combination of technical skills,people skills and wit. These technical and peopleskills helped Bill lead major projects, and the wit-outrageous puns to trenchant observations on thehuman condition-helped smooth and lubricateeverything he did.

I knew Bill a bit in the early years at SLAC-he waswith the Spectrometer Facilities Group in ESA andthen with MAC at PEP (its formal name was Big MAC,which of course he coined), but we never reallyworked together until Bill joined SLD in '83 or '84.Bill's first big project was the SLD coil-100 tons ofaluminum, glass, and epoxy. Bill was the physicistresponsible for uniting the design, getting it built byMitsubishi in Japan, getting it here, and finally over-seeing its installation and commissioning.

That project turned out to be a simple warm-up forthe next one-Bill managed the design and constructionof the final focus triplets for SLC. These projects seemsimple when they are wrapped up in their stainlesssteel cans: you pour in the helium, and they don'tquench too often-but they are not so simple. Therewere problems which were technical and there wereproblems which were style, and Bill had the skills andwit to keep things going, to help people work together,and to make the project a success.

Bill was literate and he genuinely knew how towrite and communicate. These are very valuable skills,particularly among a batch of scientists and engineers.It was these skills, in addition to his good sense, thatattracted the attention of the SLAC directorate. About ayear ago, Bill agreed to become an Assistant to theDirector. We in SLD were delighted last October whenBill decided to come back to physics full time. Bill tookon the leadership of the SLD Vertex Detector Upgrade,a difficult and technically demanding project at a timewith very tight budgets. He made the presentation forthe project to the EPAC with his usual clean deliveryand wit.Rene Donaldson remembers:

Those of us who were fortunate enough to haveknown Bill Ash have lost someone who stood at the cen-ter of our daily world-unassumingly and sometimes, Ithink, not really aware of the position he occupied inour lives. We remember him as a man of extraordinaryinner grace, whose character revealed inherent gentle-ness, intellectual depth, personal integrity, humor, greatkindness, and, above all, the conviction that we musttreat one another with kindness, dignity, and respect-though when righteous anger is called for, we shouldhave the courage to stand up and declare it.Nan Phinney remembers:

When the SLD detector was first installed in 1991, theSLC performance had been disappointing and a steeringcommittee was formed to plan the accelerator programand guide the necessary improvements. Bill Ash was theSLD representative on that committee and I worked withhim closely for the last three years. Having a calm, rea-sonable buffer between the accelerator and the experi-ment helped keep us all working together towards acommon goal. Bill was a key part of the success storythat led us from the dark days of 1990 to 50,000 polar-ized Zs in 1993 and important physics results.

During this period, there were a lot of DOE and oth-er committees at SLAC to review our performance. Billwas usually involved with these prsentations, and weworked together on what often felt like life or death sit-uations. We spent many SLAC dinners together mak-ing jokes and being silly. Those dinners will be a lotduller without Bill's sly humor. He was a joy to workwith and a very special friend.

Video teleconferencing room update

VIDEO CONFERENCE USERS have experi-enced some difficulties lately, particularly in con-necting with all conference participants. Thedifficulties were largely due to a not entirelysmooth transition from the SSC to NERSC forconference connection services. NERSC servicesare not fully operational. Also, a minimum of 24hours advance notice is required for schedulingconference facilities.

If you experience difficulties during your videoconference, please ask your conference leader tocontact the person at the Computing Help Desk. Ifthe Help Desk person cannot resolve the difficulty,they will request assistance from the appropriateTelecommunications person. Please designate aconference leader with whom the Help Desk orTelecommunications staff person can attempt toresolve the problem. Also keep in mind that wecan only correct locally caused problems or workwith NERSC to resolve connection problems.Remote participants need to work with their sitesupport organizations to resolve problems at theirlocations.

As we stated in the June 1993 Interaction Pointarticle "Video Conferencing Center Now Open,"before you can schedule a conference you needto first coordinate your conference with the peopleoffsite that you wish to conference with. After youhave coordinated with offsite participants, contactthe SCS Help Desk at ext. 4357 (HELP) or sende-mail to servdesk to schedule the conference.Allow at least 24 hours between requesting theHelp Desk to schedule the conference and thetime of the conference.

You might find it helpful to contact the leadersof the offsite participants in your conference a dayor so before the conference to ensure that theyare still planning on participating. We have seen anumber of cases where the SLAC party establish-es a connection, but one or more of the other par-ticipants don't connect from their end.

Model of Efficiency

Plating Shop & Rinse Water Treatment Plant"SLAC IS WAY AHEAD ofeveryone else when it comes totreating wastewater," reports NormDomingo, the wastewater inspectorfrom South Bayside SystemAuthority who inspects SLAC. Andthat is why he recently asked if hecould invite his colleagues for atour of SLAC to show the othershow one facility has created anexemplary model which otherscould follow. SLAC agreed to hostthe tour and a group of wastewaterinspectors, who have nicknamedthemselves the "PIGs" (short forPeninsula Inspectors Group), cameto SLAC on March 3rd.

The tour began in the PlatingShop, where metal parts are fin-ished to exacting specifications tomeet the demanding needs of re-search projects as well as to meetthe ongoing needs to maintain theaccelerator. Many applicationsrequire parts that must be platedwith copper, nickel, silver, or gold.The Plating Shop handles all of thiswith ease.

Ali Farvid, SLAC's chemicalengineer who supervises the Plat-ing Shop, showed the inspectorsaround the operation. He explainedthat the process begins with thor-oughly washing and rinsing theparts. As he described this process,Farvid showed the group of Waste-water Inspectors the many largebaths of liquids used in the platingprocess. Some of the baths containsoap solutions, strong chemicals, oracids for washing, while otherscontain plating solutions. There arealso several large baths of plainwater for rinsing parts after clean-ing and plating.

After the parts are thoroughlycleaned in the different cleaning

solutions, they are rinsed in water.A single part will usually gothrough many cycles of cleaning,rinsing and plating. Therefore, theplating process generates large vol-umes of wastewater. The rinsewater oftentimes contains toxicchemicals and metal residues whichSLAC must remove from the waterbefore the water reaches the publicwastewater system. If such toxicchemicals were allowed to enter thepublic wastewater system, theycould kill the organisms that areused to biologically treat sewageand the public wastewater facilitywould be brought to its knees.

To prevent such a tragedy, therinse water is sent to the RinseWater Treatment Plant. George Lax-son, who designed and oversees theRinse Water Treatment Plant,explained to the wastewater inspec-tors how the wastewater is treatedto remove toxic substances. Whenthe water in the rinse baths becomestoo concentrated with waste sub-stances, it is released to the Rinse

Water Treatment Plant where it istreated before joining the publicwaste water system. According toLexson, "The Rinse Water Treat-ment Plant may treat as much as7000 gallons of wastewater from thePlating Shop on a given day."

The PIGs gave SLAC very highmarks for the efficiency with whichtoxic metals and chemicals areremoved from the wastewater. ThePIGs felt that SLAC's Plating Shopand Rinse Water Treatment Plantshould serve as models of excel-lence for other facilities.

The local wastewater inspectorsmodel industry program is beingdone on a totally informal basis.However, it is patterned after anemerging program which has notyet been formalized by the Environ-mental Protection Agency (EPA).

Hats off to the folks in SLAC'sPlating Shop and Rinse WaterTreatment Plant for running a greatoperation!

Take Our Daughters To Work April 28"TAKE OUR DAUGHTERS toWork Day," planned for April 28,is a special event in which partici-pants go with their parents towork instead of going to school forone day. The program was begunby the Ms. Foundation, whichexpects to have over two millionparticipants world-wide this year.SLAC's event, sponsored by theWomen's Interchange at SLAC(WIS), is designed to introduceyoung women to SLAC and to helpthem expand their career aspira-tions. It is designed to encourage,inspire, and introduce adolescentgirls to the workplace. It will givethem a chance to experience vari-ous careers firsthand by accompa-nying their mom or dad to his orher job.

Who is invited? Girls ages 9through 15. Why girls? Researchreveals that adolescent girls gener-ally have less exposure to and

awareness of career options thanadolescent boys.

Visiting a parent's work placewill increase a girl's awareness ofsome of the options that will beopen to her in the future. Thatshould help her to make informedcareer choices.

What will they do at SLAC?The day will be very busy. Thegirls will be taken to the auditori-um by 8:30 AM to hear a panel ofguest speakers and then take atour of SLAC. They will then beprovided with lunch. After lunch,parents will pick the girls up andshow them the parent's work area.There the girls will see the kind ofwork their parent does, and inmany cases they will have anopportunity to work alongsidetheir parent. At 3:00 PM, they willreturn to the auditorium to hearadditional speakers. Parents willjoin the girls at 4:00 PM for wrap-up activities and for a group pho-to. The event will conclude at 4:30PM.

WIS needs volunteers to help onthe day of the event. If you canhelp, please call Evelyn Eldridge-Diaz, ext. 4128.

SLAC Hispanic Employee Committee Sponsors

FIRST ANNUAL CINCO DE MAYOTHE SLAC HISPANIC Employ-ee Committee (SHEC) is a newgroup for Hispanic employees atSLAC. According to coordinatorSammy Aranda, SHEC's goal is toencourage Hispanic employees tocome together as a communityand to share and preserve Hispan-ic culture and values with fellow

employees. This year SHEC pre-sents its first annual Cinco deMayo celebration on Thursday,May 5. This event will consist ofentertainment by our own AlPacheco's Salsa Band, Stanford'sMariachi Band and FolkloricoDancers, and authentic Mexicanfood, provided by El Molino cater-ing. Sponsors of the event areSLAC, Coca Cola, and Frito-Lay.

Cinco de Mayo (Spanish for the5th of May) commemorates a sig-inificant victory against France bythe Mexican army in the Mexicanrevolution. On that day in 1862the French army, after sufferingthe loss of more than a thousandmen in a fierce battle at Puebla,Mexico, was driven back to theMexican coastal town of Orizaba.This event is now celebrated withfiestas in Hispanic communities.

The event is slated to run from3 to 7 PM. Tickets will be sold atvarious locations at SLAC. Ad-vance tickets are $8 per person,$10 on the day of the celebration.The names of ticket sellers will beposted on bulletin boards prior tothe event.

If you have questions regard-ing this event, please contactFrank Martinez at ext. 3504, Sam-my Aranda at ext. 3189, or SandraCajal at ext. 4322. If you have anyexciting ideas for Cinco de Mayomail them to S. Cajal, MS 84.

Green Cards issued before1978 to be renewed

THE US IMMIGRATION andNaturalization Service has re-issued its earlier plan to replacethe old 1-151 version of the per-manent resident, or "green" card.Generally, 1-151 cards wereissued before 1978, when theywere replaced by the still-valid1-551 cards.

Petitions for renewal are dueby October 20, 1994.

Copies of form 1-90, whichtogether with the $70 processingfee are to be submitted to theINS, are available from the Inter-national Services Office in Room240 of the A&E Building. Appli-cants who cannot afford to paythe $70 processing fee mayrequest a fee waiver.

1-90 forms may also berequested by calling the INS at1-800-755-0777.

If you are unsure if you holdan 1-151 or an 1-551 green card,you may want to send anenlarged photocopy of your cardto the International ServicesOffices at MS 11, and they will tellyou which card you hold.

Also, SLAC employees whohave or will become a naturalizedcitizen of the US, are urged tobring their naturalization certifi-cate or US passport to Room 240of the A&E Building to documenttheir new status in their person-nel record.
