Elvin Harms in the Antiproton Source in 1989

20th Anniversary for Groundbreaking of Antiproton Source
This past Saturday, August 16, marked the twentieth anniversary for the groundbreaking of the Antiproton Source, which is located south of the Booster in what used to be a marshy field. Former Director John Peoples led the two-year project; the first antiprotons were produced in 1985. In the Antiproton Source, protons collide with a nickel target every two seconds to produce antiprotons for the Tevatron. Today eighteen people work to produce antiprotons. In June and July, the Antiproton Source operated for a period of more than 34 days while continuously maintaining a stack of antiprotons. Since its startup, the machine has produced just over 2.3 nanograms

of antiprotons. Department Head Elvin Harms said two years from now the Beams Division would celebrate the 20th anniversary of the first successful production of antiprotons.

First Safety Incentives Awarded to Fermilab Employees

Diana Canzone

On August 17, ES&H's Laboratory Safety Committee (LSC) awarded the first safety incentive to Diana Canzone, of Lab Services, Donald Holmgren and Sara Koepke, both of the Computing Division. Each employee received a Fermilab polo shirt with the message "First in Science & Safety." The safety incentives are part of a new program that Bill Griffing, Head of ES&H, recently started to raise awareness about lab safety. For every day that all lab sections and divisions exceed one hundred days without a DART (Days Away, Restricted or Transferred) case, a computer selects three employees at random to have their names listed on the LSC homepage and to receive the Fermilab polo shirt.

Particle physicists play hunt the particle
By Jenny Hogan

CERN´s future LHC collider. (Copyright CERN)

A competition is running to test the detective skills of the physicists who will grapple with data from the next generation of particle accelerators. They have been given two months to find secret physics hidden in a simulated data set.

The data is intended to mimic the results that will pour out from the Large Hadron Collider (LHC) when it is switched on in 2007. The LHC, under construction in tunnels beneath the French-Swiss border at CERN, will be the most powerful particle accelerator in the world.

UH scientists find subatomic puzzle
By Jan TenBruggencate, Science Writer
University of Hawai's physicists have identified a new mystery in the mind-bending world of particle physics, which deals with that flock of subatomic particles called quarks, leptons, and, in this case, mesons.

Quarks are among the smallest known bits of matter. There are six kinds, plus six matching anti-matter quarks. Mesons are made up of a quark and an anti-quark, which is to say, a particle of matter and a particle of anti-matter. Since matter and anti-matter tend to destroy each other, mesons are gone in an instant.

Good Morning!

Mike Witherell

We begin this week at Fermilab with a successful Lepton-Photon Symposium behind us, and ahead of us the challenge of making the most of the accelerator shutdown that will begin on September 8. As we approach this time of intense activity, I want to take a few minutes to recognize the flexibility, dedication and willingness to help on the part of hundreds of people throughout the laboratory. Many are leaving their regular assignments and rearranging their personal schedules, taking up new duties and joining new teams wherever they are needed, in order to devote their time, talent and energy to this shutdown, whose success will be so critical to Run II and to Fermilab. To all of those who have rescheduled vacations and reorganized work plans with such good will, I extend my personal thanks and those of the whole Fermilab community. We need you, and we thank you.

The final count for the Lepton Photon conference was 606 researchers, 22 media representatives, 36 secretariat, 11 bus drivers, 6 bus companions and 15 vendors.

- Last week Fermilab accumulated 221.5 inverse picobarns. The lab expects to exceed the FY03 goal of 225 pb^-1 before the end of the week.
- Operators set a new record for transmission efficiency of antiproton beam of 76% when transferring pbars from the Pbar Source all the way to the interaction regions at the detectors.
- Operations established three stores from Friday to Sunday. Including an already established store, the accelerators provided approximately forty-nine hours and thirty minutes of luminosity to the experiments.
- The Booster suffered a vacuum leak that required access and repair. Many other areas took advantage of this downtime and performed maintenance.
- A Linac RF station, LRF2, was off for about three hours due to a bad relay.
- The Meson Low Conductivity Water system suffered a leak.
