International Committee Meets at SLAC

LAB DIRECTORS FROM AROUND the world met at SLAC inJanuary for the semi-annual meeting of the International Com-mittee for Future Accelerators (ICFA). Hosted by SLAC Direc-tor Burton Richter, ICFA members discussed topics related toparticle accelerators, technology and design, and received up-dates on the Large Hadron Collider, the Next Linear Collider,and the future of the Internet.

David Williams, a computer specialist recently at CERN,reported that Internet reliability, bandwidth and speed werebeing affected by the increased use of the public Internet lines."Intranets and Extranets are now necessary for private traffic,"said Williams. "The American car industry is already investi-gating such possibilities. So physics must do the same."

David Leith, SLAC's Associate Director, Research Divi-sion, heads a committee of DOE laborabory scientists to lookinto challenges faced by the High Energy Physics communityin response to increasing demands for Internet use.

Chris Llewellyn-Smith, CERN Director, reported that NSFand DOE have initialed an umbrella agreement about theirshare of funding for the Large Hadron Collider, a project beingdeveloped at CERN for proton physics. Approval by Congressis expected in the Spring for this major international project.

SLAC's Dave Burke presented a status report oninterlaboratory collaboration for R&D toward a TeV-scale lin-ear collider. "The Technical Review Committee's report was avaluable exercise in developing a common language of techni-cal definitions and evaluations techniques," according to Burke.

ICFA was created in 1976 by the International Union of

Members and guests from the ICFA meeting at SLAC in January.

Meet Ree Dufresne

ON HER FIRST DAYas coordinator for theSLAC Users Organi-zation (SLUO), ReeDufresne found outthat her immediatetask would be logisti-cal arrangements forthe SLAC 2000 NewIdeas Forum. Thismeant communicat-ing with high en-ergy physicistsaround the world, re-questing topics for theForum.

"Nothing likejumping right into ajob," said Dufresne.

Then, two months later came the SLUO AnnualMeeting which involved communicating with more than1100 users from activities such as BaBar, SLD, E-155, andGLAST. "Thanks to Karen Heidenreich and Sonja Cronin,"said Dufresne, "SLUO is now working on Data Client totrack users as they come and go from here to their homeinstitutions and back. This system will make a big differ-ence for the SLUO Executive Committee."

As Coordinator, Dufresne works closely with theSLUO Executive Committee, which represents the Users.The Committee works to help maintain SLUO's integrityand, at the same time, help integrate users into the fabricof the SLAC environment to facilitate smooth researchprojects.

The SLUO Executive Committee is recommendingchanges that will make SLAC more user friendly. Usersmay now get a SLUO information sheet and a ComputerAccount request form by simply e-mailing Dufresne aFAX number to SLUODESK@slac.stanford.edu. If theperson is a User who will be physically working on-site,a visit to the SLUO desk in the Central Lab Annex will getthe User all the necessary information to complete ES&Hrequirements, be photographed, badged, and directed tothe appropriate Group Secretary.

In addition to opportunities which exist on Campusfor auditing physics classes, SLUO is now offering classesto Grad students and users on Friday mornings here atSLAC. The Series on Supersymmetry taught by MichaelPeskin will be completed in February. A new Series on CPViolation taught by Helen Quinn is also being scheduled.Dufresne provides the logistical coordination for thesecourses.

So what has it been like in just one year? "A rollercoaster ride," said Dufresne, "and I truly enjoy it."

LaTeX with the Ease of Word?THE TECHNICAL PUBLICATIONS Depart-ment is considering proposing the purchaseof a site-license for a powerful authoring ap-plication, Scientific WorkPlace. TechPubs issoliciting feedback from members of the sci-entific and technical authoring community atSLAC who have used Scientific WorkPlaceor are interested in it.

Scientific WorkPlace provides aWYSIWYG ("what you see is what you get")front end to a LaTeX compiler. This powerfulprogram allows those working on a PowerMacor PC (Windows 3.1 and up) the ease ofauthoring found in products like MicrosoftWord (but with a much better math module),combined with the high quality of type-set-ting afforded by LaTeX.

At the VM Phaseout Fair held in Febru-ary, many authors who tried out the applica-tion were enthusiastic about the functional-ity of the embedded Maple kernel, whichallows authors to evaluate, graph, or plotequations all within the document authoringapplication. The program also allows usersto link to Mathematica.

Scientific WorkPlace comes equippedwith a suite of more than 100 document tem-plates. For the VM Phaseout Fair demo,TechPubs staff also pre-loaded the applica-tion with LaTeX templates designed for SLACPubs and Reports.

Authors familiar with this applicationare invited to give feedback in the evaluationprocess by using the WWW form at:http://www.slac.stanford.edu/grp/techpubs/ announce/ sciword.html

Those interested in finding out moreabout the application or trying it out them-selves, please send email to Ruth McDunn(mcdunn@slac.stanford.edu).

Sixth International World Wide Web Conference: April 7-11

"REGISTRATION IS UP!" says Bebo White, co-chairof the WWW6 conference to be held at the SantaClara Convention Center. Co-sponsored by SLACand Stanford, the conference takes place from April7-11. Details can be found at:http://www6conf.slac.stanford.edu

A now-annual event, the Web conference isorganized under the auspices of the InternationalWorld Wide Web Conference Committee. The con-ference fosters development of the Web by provid-ing a forum for discussion and exploration of theunderlying technology. The conference will havetutorials, workshops and three days of papers andpanel presentations. Volunteers are needed. Seethe Web pages for how to sign up.

Recently confirmed speakers include TimBerners-Lee providing the keynote address. Fol-lowers of history will need no introduction toBerners-Lee, but Luddites may be interested to

know that he is the man who invented the Web atCERN. Other speakers include Mae Jamison,former NASA astronaut; Howard Rheingold, origi-nal Well developer; and Paul Saffo, Director of theInstitute for the Future.

An important topic at this conference is a daydevoted to developers. "Developing for the Webis now a complex business proposition," says NickRagouzis of the Enosis Group. "This day is de-signed to appeal to those trying to move theirproduct development and business operations tothe next level." Developers Day, Friday, April 11,will have a three-track program on architecture,user interface, and technology and society.

The WWW6 conference will be sharing somesessions with Computing in High Energy Physics(CHEP) in Berlin, Germany and Hypertext 97 inSouthhampton, England.

Demand for MES Beamtime at SSRLSYNCHROTRON-BASED SPECTROSCOPIC tech-niques have proved to be essential tools for solvingmany types of environmental problems facingsociety today. For example, X-ray absorption finestructure (XAFS) spectroscopy is used todetermine the speciation of toxic contaminantssuch as arsenic, lead, and uranium in contaminatedwaters, soils, plants and microbes. XAFSspectroscopy is also used to characterize thestability of fissile materials, spent nuclear fuel,and high-level radioactive waste. Othersynchrotron-based techniques including X-rayscattering methods, X-ray imaging andmicroprobe techniques, and infrared spectroscopyare also important tools for environmentalscientists. These techniques probe the molecularstructures, long-range average structures, andoxidation states of ions, and their application toenvironmental studies had led to the developmentof a new disciplinary field, MolecularEnvironmental Sciences (MES). The success ofsynchrotron techniques in solving MES researchproblems has led to rapid growth of the MESsynchrotron user base, and substantial increasesin demand for MES beamtime. For example, MESresearch at SSRL has increased approximatelythree-fold since 1993.

A working group was recently convened atSSRL on January 18-19 to study the rapid rise indemand for MES beamtime and facilities, and tomake facilities recommendations to accommodatefuture MES synchrotron research needs. Thoseattending the meeting included 13 scientists fromuniversities and national labs who are activemembers of the MES research community, and 7

representatives from the four DOE-funded nationalsynchrotron laboratories, who provided technicalinformation and operations knowledge about thefacilities. It was concluded that current andplanned US-DOE synchrotron facilities should beadequate for MES beamtime and facilities needs inthe near future, i.e., 1997 and 1998. Beyond thistimeframe, however, it was anticipated thatadditional MES synchrotron facilities will beneeded, due to an increase in the application ofsynchrotron-based spectroscopic and x-rayscattering methods to environmental basic researchand engineering areas, where these techniques havenot yet been applied(such as for routineenvironmental monitoring programs). MESoperations and user support models were alsodiscussed, and recommendations for futurefacilities were made.

The SSRL MES program at SLAC figuredprominently in discussions during the workshopas a model for MES efforts at other US synchrotronfacilities. The SSRL MES staff is composed of Drs.John R. Bargar and Gordon E. Brown, Jr., whoconduct basic research and provide support forMES users. Another important component of theSSRL MES program is the high-flux MES-dedicatedbeamline (BL-11), which is currently underconstruction and will feature a chamber forexperiments with toxic and radioactive samples, ahigh-throughput multi-element detector withadvanced signal-processing capabilities, and otherequipment suited to MES research. MES plans forthe future at SSRL include the hiring of technicalsupport staff to run BL-11 and providing usersupport for MES researchers.

Attention QuickMail Users

BEGINNING MARCH 1, 1997 each time the QuickMail utility

(MAT) is run (normally once a month), any Mail or Mail Log files

residing on the QuickMail server older than 120 days will be

deleted. Also, any QuickMail account that has been inactive for

more than 120 days will be deleted and no new QuickMail

accounts will be established.In mid-January the QuickMail server crashed at least three

times. Bringing it up after the last crash and running the monthly

utility was difficult and costly. Many older files were deleted.

Crashes and problems seem to occur more often when there is a

large volume of files left on the server. Before this last crash

there were close to 20,000 files on the server.

All QuickMail users are highly encouraged to Save or File

(or Delete) your Mail and Mail Log files to your Mac, and not

leave them on the QuickMail server.

Mac users should also look into moving off QuickMail and

onto Eudora. Eudora is the supported mail system for Macs,

whereas support for QuickMail has been reduced. (People in the

PEP-II Division, and those people in other Divisions doing PEP-

II related work, should remain on QuickMail until the end of the

PEP-II project. This will minimize the risk of disruptions to their

e-mail communications, especially with collaborators from other

labs who are also on QuickMail.)SLAC does not intend to make any further upgrades to the

QuickMail software. SCS will continue to provide central

QuickMail support until the B-Factory construction project fin-

ishes, or until the current software breaks or becomes unmain-

tainable in a cost-effective manner, whichever comes first. This

is due to: the high cost of support for QuickMail in the SLAC

environment, and the availability of Eudora as an alternative

supported device.If you no longer need your QuickMail account, please

notify the HELP desk at x4357 and ask to have your account

deleted. Be sure to Save or File any mail files you want to keep

before having your account deleted.

See this web page for more information on Eudora:

ISDN ProposalApproved

A PROPOSAL TO PROVIDE a pro-

duction Integrated Services Data

Network (ISDN) service was pre-

sented to the Associate DirectorsCommittee on Computing (ADCC)in January, and met with a favorableresponse. The full proposal and the

Executive Summary are viewable on

the Web.The production ISDN service

would be an upgrade and expansionto the current ISDN Pilot model. The

current model is not cost effective to

build on from a financial, techno-logical, management, or security

standpoint.The proposed model will sup-

port 46 simultaneously-connectedusers from a pool of about 140 users,

with the capability of doubling that

capacity if needed. There will also be

better security and management tools

will be included. (The current model

allows 9 simultaneously-connectedusers from a pool of 22 users.)

An Internet Service Provider

(ISP), WinterLAN, was also recom-mended for users living outside the

local calling area from SLAC. The

local calling area is roughly within a

12 mile radius of SLAC which Pacific

Bell defines as the users' phone num-

ber prefix.For more information on the

proposal and ISDN, see the follow-

SHARON TRAWEEK, knownfor her anthropological view ofSLAC and KEK in the book BeamTimes and Life Times (1988),spoke at campus recently on thetopic "Cultural Reality Wars."She argued that the United Statesis 25 years into a social disloca-tion creating new language,models, templates and para-digms. All of these have seriousimplications for what researchis funded, since "some knowl-edge is prized, while otherknowledge is despised," accord-ing to Traweek.

"How do we make knowl-edge? What are our tools, sites,and methods?" Responding tothese rhetorical questions,Traweek reviewed 750 years ofhistory and the different meth-ods of categorical thinking usedin the past: from the use of dy-ads such as light and dark (orCoke and Pepsi), to triads (Fa-ther-Son-Holy Ghost), and natu-ral laws (the speed of light). Allthese methods are commonlyused and accepted as ways ofknowing.

Since WWII, however, newways of thinking have influ-enced the knowledge that is cre-ated, funded, and disseminated.These new methods are heavilyinfluenced by computers andtechnology. An example citedby Traweek was the grocerystore middle manager who usedto decide what products to buy,what price to sell them, when toship, and how much to keep instock. Now, computer scanners

read bar codes and productsare ordered using just-in-timeshipping. The personalknowledge of the relationshipbetween the customers and theproducts in an individual storeis no longer valued.

With some trepidation,since she is a professor atUCLA, Traweek drew a paral-lel to deans, department chairsand other academic personnelwho are responsible for logis-tical arrangements of studentsand class timetables, wonder-ing what the future brings forthis group. "The tools that weuse may become the mastersof the process, not the scholarwho uses the tools," cautionsTraweek.

Science is caught in thisparadigm shift. The currentanti-science mood, as exem-plified by the cancellation ofthe SSC, was "the revenge of Cstudents," a remark Traweekquoted from ex-SSC lab direc-tor Roy Schwitters.

What are the implicationsfor those in the midst of thissocial dislocation? "There is afault line for those who areover or under the age of 45.The older group grew up with-out copy machines and com-puters. The younger grouphas this technology," saidTraweek. She suggests thatworking at the fault line cre-ates a tension necessary for asuccessful transition to thenext paradigm, whatever thatmight be.

Professor EmeritusBenjamin M. Page Dies at 85

BENJAMIN M. PAGE, Professor Emeritus of geology, and oneof the leading experts on the formation of California's coastalranges, died at his home in Palo Alto on January 31 at age 85.Memorial services were held at Stanford Memorial Church.

Page received all three of his academic degrees fromStanford, all in geology. He joined the faculty at Stanford in1943, and led the Department of Geology as chair from 1957 to1969. Though he took emeritus status in 1976, he remainedactive in research and teaching, publishing some of his best-known scientific papers. From 1985 to 1988 he edited thejournal Tectonics.

He had a particular interest in the geology of Stanford andthe Bay area. Wolfgang Panofsky, founding director of theStanford Linear Accelerator Center, credits Page for the geo-logical studies that allowed engineers to place the two-milelong particle accelerator on safe foundations. According togeology Professor Emeritus Robert Coleman, "His scientificwork helped us understand and cope with the geological haz-ards related to earthquakes, landslides and flooding in the Bayarea."

At a 1993 division session of the Geological Society ofAmerica, Page accepted an award honoring him for a career ofcontributions by quoting wisdom he said he had gained from apredecessor. The late professor C.F. Tolman, he said, taughthim a profound fact: "One day while in a reflective mood,Tolman said to me, 'You know, Ben, people are almost asinteresting as rocks.' "

At SIAC, Dr. Green's research has focused on appliedsolid state physics with emphasis on semiconductor surfacesand interfaces. He has also been involved in materials andadvanced coatings for robust field emitter technology, leadingto the development of advanced infrared detectors andmicroantenna technology.

Green is continuing his interest in education in a varietyof ways. In 1993, he hosted a PBS-TV children's show "Newton'sApple," where he explained the general principles of electro-magnetism. As co-founder and board member of MinorityStudents in Physical and Mathematical Sciences based inWashington, D.C., he encourages undergraduate students inthe physical sciences to pursue graduate degrees.

Alan HacKelmann ( r acceuupi u/inercertificate from Jym Clendenin.

BECAUSE OF RESTRICTED AC-CESS and special safety consider-ations, the job of keeping the ac-celerator housing (the below-ground areas) clean has becomeincreasingly more difficult. Dur-ing the past 6 months, while theaccelerator was shut down, theArea Managers were in friendlycompetition to see in which areathe cleanliness could be most im-proved.

Just before the lock-up of thehousing for the start up of E-155,the area judged to show the great-est improvement was determinedby Jim Allan (ES&H) to be theDamping Rings. The award (afully-paid dinner for 2 at EvviaRestaurant in Palo Alto) was pre-sented at the 08:15 AcceleratorMaintenance Meeting on Febru-ary 13 by Jym Clendenin (SLCphysicist) to Alan Rackelmann, theDamping Ring Manager.

Other Accelerator Area Man-agers are: Al Baker (Arcs and Fi-nal Focus), Roslind Pennacchi(Linac Area), Patrick Smith (In-jector), Robin Gray (PEP-II), andJoe Sodja (Injector).

FactinOsPaychecks New Look, Same Old MoneyIt's Still your SLAG paycheck, but starting March 22, it will be

different. Sorry, no, there's no increase in the amount ofmoney printed on them. But SLAC checks will have a newdesign, according to Carol Tam, SLAC Payroll Manager. Inpreparation for our new Business Information Systems (BIS)which will use the PeopleSoft software application, a laserprinter will print payroll checks. Facsimiles of the old andnew checks will be distributed to staff for comparisonsometime in March.

Chain Letters a No-NoEither hard copy or electronic, chain letters sent using SLACcomputers typewriters, printers, or paper are a misuse ofgovernment property. If you know someone who is sendingthese kinds of messages, please let them know it's a no-no.

Did you know?No parking? It might be because the number of users(researchers from around the world) has increased to nearly2000. Users come from 100 US universities, 20 nationallaboratories, and more than 100 foreign institutions. Half ofthis number are in high-energy physics, and the other half inthe synchrotron division. HEP researchers work for severalyears on long-term collaborations, while SSRL users typicaare here for one or two weeks for use of beam lines.

Praise for PurchasingLet's hear it for the Purchasing Department! Records showthat SLAG purchases $1 w orth of goods and services for whatis known a a process cost oonly $.0215. This figure putsus ahead of other Labs, with the Thomas Jefferson facility(formerly CEBAF) coming in at $.023.
