As they clearedsecurity at the entrance tothe Old Executive OfficeBuilding across the streetfrom the White House, guestsand dignitaries bound for theDecember 8 signing ceremonyfor the Large Hadron Colliderdonned mandatory plastic ID tagsstamped with the words “LargeEvent.” Looking around at the tagsadorning the veritable Who’s Who ofU.S. particle physics and Washingtonscience hands filling the ornate Indian

Treaty Room, CERN Director-General Chris Llewellyn Smithposed a question.

“By ‘Large Event,’” hewondered, “do you thinkthey mean the Higgs?”

Whether or not thenew Large HadronCollider to be built atCERN, the EuropeanLaboratory for ParticlePhysics in Geneva,ultimately identifiesan event containingthe putative mass-conferring particlecalled the Higgsboson, theceremonyconfirming

be delivered to CERN, will total $531 millionover eight years, with $450 million comingfrom the Department of Energy and theremaining $81 million from NSF. In fiscal year1998, Congress appropriated $35 million forLHC work. When experiments begin inanother decade, about 25 percent of Americanexperimental particle physicists say they plan to collaborate on experiments at the LHC.

Physics without bordersLlewellyn Smith cited the universality and

openness of science as a reason that scientificresearch should be carried out in internationalcollaborations, not hemmed in by borders orcultures.

“The signature today of the cooperationagreement between the United States ofAmerica and CERN is an historic event,” hesaid. “It is an important step towards the first-ever global collaboration in a large scientificconstruction project. American participation inthe Large Hadron Collider will inject a wealthof scientific experience, excellence andcharacteristic exuberance into the project.”

The LHC, whose total price tag will equal about $6 billion, will occupy an existing16-mile tunnel that currently holds the LargeElectron-Positron Collider. The LHC’s collisionenergy of 14 TeV will be seven times higherthan that currently achieved at the Tevatron. Its energy will reach a scale at which physicistsbelieve they may find the answers tofundamental questions about the origins ofparticle mass. They hope the LHC may alsooffer a pathway to physics beyond the well-worn Standard Model, the current theoreticalpicture of particle interactions.

Fermilab, the LHC and the future

U.S. participation in the LHC will haveimportant consequences for Fermilab. TheTechnical Division’s Jim Strait is the projectmanager for the U.S. contribution to theaccelerator, leading a collaboration that includesBrookhaven, Lawrence Berkeley and Fermilab.Much of the R&D and fabrication for advancedsuperconducting quadrupole magnets for theaccelerator’s interaction regions will take placein Fermilab’s Technical Division.

In addition, in 1997, officials of DOE and NSF asked Fermilab to oversee projectmanagement for the CMS detector, one of theLHC’s two major detectors. Fermilab is thehost laboratory for U.S. CMS, for whichFermilab physicist Dan Green is technicaldirector.

“Physics is a discipline without nationalborders,” Green said. “Since the possibility ofbasic discoveries in particle physics is large at

An unprecedented partnershipIn what they all described as an historic

act of international scientific collaboration, U.S. Secretary of Energy Federico Peña,National Science Foundation Director NealLane, CERN Council President LucianoMaiani and Llewellyn Smith signed anagreement under which the U.S. will help build the new accelerator and two of itsassociated detectors. When it begins operatingsometime after the year 2005, the LHC willtake over the energy frontier from Fermilab’sTevatron, currently the world’s highest-energyparticle accelerator.

Although international collaboration haslong been a hallmark of particle physics, withscientists from many nations getting togetherto build detectors and operate experiments, the new agreement calls for unprecedentedworldwide partnership in the construction of anaccelerator itself, traditionally the responsibilityof the host country.

“When we sign this agreement,” Peña said,“it will mark the first time the U.S. governmenthas agreed to contribute significantly to theconstruction, through domestically produced-hardware and technical resources, of anaccelerator outside of our borders.”

Besides CERN’s 19 European memberstates, which for over 40 years have chipped into build and operate the high-energy physicsfacilities at the laboratory, several non-memberstates—including the U.S., Canada, Japan,India and Israel—have agreed to contribute tothe new LHC collider and detectors. The U.S.contribution, largely in the form of acceleratorand detector components built in the U.S. to

the energy frontier, it is vitally important thatU.S. physicists have the opportunity toparticipate as full partners in the LHCadventure. The recent agreement betweenCERN and the U.S. ensures that partnership.”

Although it might seem puzzling thatFermilab would welcome the opportunity tohelp build the accelerator that will one daysupersede the Tevatron, Laboratory scientistshailed the signing ceremony as a landmark ininternational cooperation that will benefit notonly particle physics research but Fermilab itself.

“Collaborating with CERN on LHC isgood for Fermilab because it is good forscience,” Strait said. “The science of LHC iscompelling, and we can help ensure that it isdone more quickly, through our work on theaccelerator, and better, through our work onCMS. Our work on LHC keeps Fermilab andthe U.S. high-energy physics community deeplyinvolved in the physics at the energy frontier,and our work on the detector and acceleratorwill help keep our technological abilities at theforefront. This will help make us a credible hostfor the construction of a future higher-energycollider. The only way such large facilities can bebuilt is by worldwide collaboration, and ourcontribution to the construction of the LHCwill help establish the principle and habit ofaccelerator builders working together acrossinternational boundaries.”

However, the path to a future U.S.accelerator is by no means certain. Althoughthey repeatedly cited the LHC agreement as anexcellent precedent in global collaboration and amodel for other fields, both European and U.S.officials were careful to avoid establishing anyquid pro quo for future accelerator construction.In response to a reporter’s question whetherEurope is now committed to support U.S. high-energy physics facilities in the future, Ph

A recent symposium brought together accelerator experts and experimenters to start talking about

Near-Beam Physicsby Sharon Butler, Office of Public Affairs

Close to the beam lie physical events that scientists are eager to probe—like eventsinvolving b quarks and the bound states of b quarks and antiquarks called B mesons. Here,scientists are exploring a fundamental question:why the universe holds more matter thanantimatter.

Close to the beam, too, physicists alsoexplore the collisions of proton and antiprotonsslightly nudged out of line, as little pieces ofprotons called pomerons bump into quarks andgluons.

But cozying up to the beam can behazardous. Stick a precious silicon vertexdetector too close and it might just get blasted,suffering irreversible radiation damage. For thebeam comes on with “the energy of a Macktruck,” said physicist Dick Carrigan.

That’s why he and his Fermilab colleagueNikolai Mokhov organized a symposium lastSeptember on what they called “near-beamphysics”—to get accelerator specialists talkingwith high-energy physicists. As Carrigan noted,“you need a certain kind of beam to do thiskind of physics.”

Close byCarrigan says that the term “near-beam

physics” was just a phrase the organizers of thesymposium “pulled out of a hat.” It refers tothe domain of high-energy physics experimentswhere particle detectors work only fractions ofan inch from a circulating accelerator beam.

In recent years, the pursuit of this kind ofphysics took off when silicon vertex detectorswere introduced. With a particle beam shootingby only an inch or so from these detectors,physicists have been able to measure thedisplaced vertex associated with b quark decays.

“People got more and more interested inseeing how close to the beam they could get,”said Carrigan. “Instead of something the size of a paper towel roller [wrapped around thebeam], they wanted something the size of a pen.”

A number of devices now exist for probingnear-beam physics, all of them daring to getclose to the beam. One popular device is theRoman pot, whose pioneer, Giorgio Matthiae,of the University of Rome, gave theintroduction to the three-day symposium. TheRoman pot, which could be mistaken for a

shiny stainless-steel flower pot, is controlledremotely, moving in on accordion-like bellowsthat retain a vacuum. Inside the pot sits a smallscintillating fiber or silicon detector. Once thebeam stabilizes, the Roman pot can get as closeas four to eight beam diameters (about the sizeof a pencil lead) from the beam axis, accordingto speakers at the symposium.

Other devices operating close to the beaminclude crystal and wire targets, which arepositioned closer still, at 3 to 4 beam diameters.

A wire target is used in HERA-B, the B-physics experiment at DESY (the DeutschesElektronen Synchrotron in Germany). DESYphysicists Carsten Hast Klaus Ehret andMichael Bieler reported on the status of thatexperiment.

Crystals are used in extracting beams froman accelerator—for fixed-target experiments, forexample. Speakers from IHEP (the Institute forHigh-Energy Physics in Russia), CERN (the European Laboratory for Particle Physics)and Fermilab reviewed extraction, includingpioneering work using crystals.

Taming the beamOne problem for physicists probing events

astride the beam is the “beam halo,” a cloud ofparticles around the beam—“little outriders,”Carrigan called these wayward particles, “likeflies following a cow around.” They get in theway of experiments, causing background noiseand, worse, crashing into delicate detectorcomponents and damaging them forever.

There is as yet “no nice theoreticalunderpinning to predict this phenomenon,”says Carrigan, “no tidy theory using nonlinearbeam dynamics.”

Near-beam physics experiments need aminimum halo so that the beam is clean anddetectors can move in as close as possible. One method of trimming the halo is to usecollimators, which block the path of theirritating flies. Experimental and theoreticalwork on collimation has illuminated aspects ofthis halo phenomenon, and reports on thesestudies were included in the symposium.

Near-beam physics also requires that thebeam be closely monitored and its orbitcorrected and stabilized, and Fermilab staffAlan Hahn and Vladimir Shiltzev discussed thespecial instrumentation that keeps theTevatron’s beam on track. ■

“Dear Mr. Ellis....”

Fermilab’s Keith Ellis—theoretical physicist, Esmé’s dad and a “nice gye.”

How do you use mathematics in your work?

That was the question Fermilab physicist Keith Ellis, head of the Laboratory’sTheoretical Physics Department, was invitedto answer recently for his daughter Esméand her second-grade classmates. Mr. Ellis’sclassroom presentation—he discussed mathin his job and passed out photographs ofFermilab’s Wilson Hall by moonlight—appears to have met with the approval ofthe second grade. Their illustrated thank-younotes expressed admiration for Esmé’s dad,his line of work and his office building.

And just how does Mr. Ellis usemathematics in his work?

“I explained that all the stuff around usis made of little bits,” he said, “and youneed mathematics to watch ‘em.”

Did the kids have questions?“Yes,” Ellis said, “they wanted to know

how long it takes me to get to work.”

him talking, and he’s passionate about equalemployment opportunity. He effuses, too,about the public relations value of Fermilab’sK–12 education programs, programs he helpedsave from near-extinction two years ago whenDepartment of Energy funding dried up.Marofske may fret over the number of times hehad to say no as head of Human Resources,but there were many times when he said yes.

Marofske has decided it’s time for him, not just his ties, to retire. He thought long andhard about the things he’ll miss: “being part ofthe excitement, sharing the tragedies and thegood times, even the arguments [he catcheshimself: ‘the discussions’].” A stash of photosin his desk drawer recalls the lively parties—all well-earned, he quickly points out—whenstaff took turns in the dunk tank and Adam and Eve once showed up with a live snakedraped around their naked arms. But hewanted to leave, he said, while he “still felt like doing things.”

Those things do not include golf. Staffremember the time he whacked a golf ballharder and harder, and still it just bumped itsway down the green.

But gardening: “I monkey around in my own backyard,” he says, and now he’ll be monkeying around in his daughter’s. Shewants lilacs; he wants peonies. He likes theperennials—when they come back, “it’s likerenewing a friendship.”

Which he’ll be doing with his long-timefriend, former head of Fermilab’s employmentoffice Jim Thompson, who just had a hipreplacement. Marofske kids Thompson that, for the winter months, they’ll be mall walkers.“So, if you ever take a day off,” Marofske says,“and you’re walking around the mall and yousee these two old guys, be kind.”

Marofske has promised he’ll stay on longenough to train his successor. Then he’ll go,and bequeath to the next boss his old metaldesk, the same one he’s had for 30 years. ■

these days is positively radiant. That’s because,after 30 years at Fermilab, Marofske no longerneeds his 6:15 wake-up bell. He’s retiring,taking with him a trove of memories.

Marofske started at Fermilab back in thedays when men wore ties. He first shed his inthe early 1970s, when the energy crisis hit andpeople dressed more casually to cope with thesummer heat. Marofske says he quicklydiscovered he could “yell louder without a ropearound [his] neck,” and never wore one again.Now, if his pension falls short, he says, well,there’s that closetful of ties.

It was in coat and tie in the old Oak Brookstorefront that Marofske first took charge of thehiring and firing at Fermilab. He still has theyellowed ledgers with the initial handwrittenlog of entries and departures, and thenumbering system he invented to identifyemployees. Now, nearly 12,000 people havepassed through Fermilab’s doors, all by way of Marofske’s office suite.

Marofske held the same job for 30 years—head of Laboratory Services—but his portfolio kept expanding. Today it includesresponsibilities as diverse as the cafeteria, visualmedia, the library and human resources. Heshaped and implemented not only a set ofpersonnel practices, but a policy of reaching outto minorities that was far ahead of its time. Get

Reports Identify Causes of Electrical AccidentFermilab and DOE cite problems in planning, supervision andcommunication. Corrective actions are under way.

by Sharon Butler, Office of Public AffairsThe Fermilab report is seven pages

long, the Department of Energy’s 37-plus. But both reports say the samething. An electrical accident thatoccurred in October could have beenavoided if the work had been properlyplanned, supervised and carried out, andif there had been better communicationbetween Fermilab and the contractorperforming the work.

The accident occurred when twoemployees of Arbor Electric Companywere installing temporary wiring to runlights, heaters and an elevator in theTevatron’s FZero Service Building. Theelectricians, who assumed the power tothe building was off, were looking for aplace to connect a neutral wire. Findingnone, they tried removing the cover to amotor control cabinet, hoping to find aplace inside. When they did that, thecover contacted the energized wire, ashort occurred, and an arc of electricityflashed across the frame. Both menreceived burns to their hands; one manreceived burns to his face.

According to both the DOE and theFermilab report, the accident occurred inpart because planning for the task andcommunication between Fermilab andthe contractor were inadequate.Specifically, the DOE report said, “therewas no work documentation and noengineering drawings of the electricalsystem for the job”; consequently, “the electrical hazards could not beadequately assessed or addressed.”Certain safety precautions were neverdiscussed, the agency report said.

Also, neither Fermilab nor ArborElectric staff supervised the work toensure it was done safely. “Had someonevisited the work site [while the work wasunder way],” the Fermilab report said,“the question of where to connect theneutral could have been raised andaddressed before the shield [the cabinetcover] was removed.”

Both reports noted that neitherlocks (shutting out the power) nor tags(identifying who was working on thecircuit and when) were placed on thecircuits leading inside the cabinet.LOTO, as the procedure for locking outand tagging is called, is standard practiceat Fermilab and in industry whenindividuals are working with energizedsystems, according to Mary Grace, who,as associate head of Fermilab’sEnvironmental, Safety and HealthSection, led the Laboratory’sinvestigation of events surrounding theaccident. The contractor should havelocked out the circuits and verified thatthe circuits were deenergized beforebeginning the work.

A team headed by Jim Finks, ofBusiness Services, identified several

corrective actions to address theproblems identified. In future contracts,Fermilab will require that contractor staffbe both knowledgeable about andtrained in the safety hazards involved inthe assigned tasks. Work will need to bescoped and hazards analyzed even forfield changes (smaller construction tasksnot originally specified in the contract).Those requirements will be included intraining for task managers. Fermilab willalso develop a policy and guidelines forformally documenting hazard analyses,so that communication betweenFermilab and its contractors improves.Finally, a forthcoming letter from theLaboratory Director will reemphasize theimportance of not allowing cost andschedule to compromise safety. ■

by Judy Jackson, Fermilab Office of Public AffairsAmong the experiments conducted at

Fermilab in 1997 was an exploration of newways to decorate the Wilson Hall atrium for the Christmas season. In an effort to find adistinctive Fermilab style for the holidays—festive, colorful, environmentally correct, non-sectarian, and possibly even educational—stafffrom the Facilities Engineering Services Sectionand the Office of Public Affairs collaborated increating and hanging banners depicting topquark events from particle collisions at CDFand DZero.

A set of eight colorful postcards, designedby Fermilab theorist Chris Quigg and graphicartist Bruce Kerr, in consultation with CDFand DZero collaborators, inspired the bannerdesigns. The postcards show accuraterepresentations of particle collisions at the two experiments, with colors and orientationchanged by the artist for visual impact. Theyhave proved popular with visitors and membersof the Fermilab community. The bannerstranslate the postcards into four-by-six-footimages printed on canvas and hung fromflagpoles.

Although reaction from the Fermilabcommunity to the holiday banners was mostlypositive, it was by no means unanimous.

“I really like the banners,” e-mailedastrophysicist Rocky Kolb. “It gives the atrium

a warm ‘medieval times’ feel. It will beappropriate for the jousts between CDF and DZero.”

Fermilab physicist David Christiancomplained that the banners looked “tacky”and wondered if “Mickey Mouse on a bungeecord” would be next.

Angela Gonzalez, artist and aestheticconsultant, expressed strong distaste for theinnovation, quoting Goethe to make her point:“Den Geschmack kann man nicht am Mittelgutbilden, sondern nur am Allervozueglichsten,”which she translated as “(Good) taste cannotbe achieved by learning from the mediocre (I add trash, there is not even much ‘mediocre’left to go by) but only from the mostexcellent.”

But the prevailing sentiment warmlysupported the particle pennants as distinctiveFermilab holiday symbols. Many requested thatthe quark-spangled banners continue to waveafter the holidays were over. However, thebanners will go into storage in January at leastuntil another holiday season rolls around,Public Affairs officials said.

Will the Christmas banners become aFermilab tradition? Will it be “Deck the Hallswith Quarks and Leptons!” or “Fling out theBanner!”? Stay tuned. ■

DOE’s Martha Krebs replied that the LHCagreement was most useful in establishing ageneral framework for collaboration in largescientific projects in many fields, not simply inhigh-energy physics.

“Does that mean that there is no agreementfrom Europe?” another reporter pressed.

Llewellyn Smith replied that looking atinternational collaboration “project by project,in a given field, is not a good idea. However,this agreement will make it more likely thatmany people in many different fields will find it easier to reach international agreements.”

Civics 101Reaching the international agreement for

U.S participation in the LHC was by no meanseasy. Representative James Sensenbrenner (R-WI), Chairman of the House ScienceCommittee, among others in Congress, raised strong objections to the U.S.-CERNagreement as originally proposed, impellingDOE and CERN officials to modify the terms of U.S. involvement.

“We have had a crash course in theAmerican system of government,” LlewellynSmith told the gathering. “Although at times itseemed to be much more complex than particlephysics—and I am still not sure that I know the answer to the question: who decides inWashington?— we seem to have survived to the end of the course.”

The Europeans should probably not putaway their Washington guidebooks quite yet. As U.S. particle physicists know, when onecongressional budget cycle ends, another begins.Observing the jubilant festivities surrounding thesigning ceremony, a senior congressionalAppropriations Subcommittee staffer smiled.

“This is great fun,” he said, “but next year it will be back to square one.” ■

CALENDAR

Last Friday the Lab hosted a lunch inrecognition of my and lots of others’ 20 yearsof service. I realize these events go largelyunnoticed by the rest of the Lab, but I’m sure I speak for everyone there in saying thank youto our Director, to Reidar Hahn, and especiallyto Tita Jensen and the entire staff at ChezLeon. It’s easy these days to be overwhelmedby MIR, LHC, WBS, LOTO, and even LCW,but nice to know the pace can slow just longenough to remember it’s the people who makeFermilab endure.
