Feynman Computing Center Installs Two New Uninterruptible Power Supplies
Vicky White

The Computing Division has prepped Feynman Computing Center(FCC) for significant expansion by installing two new uninterruptible power supplies (UPS). The two new UPS boxes increase capacity by 50% and will support hundreds of new computers, making sure that no chip is left behind. Sudden loss of power to the FCC's computers would cause much of the lab to grind to a halt. "If this building goes down, a lot of bad stuff happens," says Vicky White, head of the Computing Division.

"Bad stuff" includes equipment damage, expensive downtime from physics processing, and loss of network connectivity. Fermilab suffers several power outages a year, and the UPS system provides the FCC's computers with a constant supply of electricity until the backup generator kicks in. According to Gerald Bellendir, Associate Head of Computer Facility Operations, the computers "never notice-they don't miss a cycle." Jed Brown, Associate Director of Operations, points out that the service is "vital to the lab. This is where users come from all over the world to get data."

UH gets $35 million to join hunt for elusive neutrino
By Beverly Creamer The University of Hawai'i has landed a $35 million, five-year grant from NASA to capture ultra-high frequency neutrinos in the Antarctic ice sheet with the hope of better understanding the origins of the universe.

It's the largest single grant awarded to the Department of Physics and Astronomy and likely the largest ever won by the university as a whole.

Fermilab Result of the Week
CDF reports new new measurement of pomeron production ratio
CDF Result of the Week
Schematic diagrams of proton-antiproton single diffraction and double pomeron exchange (Click on image for larger version)
A collision between a proton and an antiproton at the Tevatron looks like a fireworks explosion producing close to a hundred different particles flying in all directions. However, at the Tevatron there is sometimes a large angular region relative to the antiproton beam direction that is empty of particles. Such patterns are thought to be caused by an antiproton emitting a "pomeron" which collides with the proton to produce a lop-sided explosion. In technical jargon, an event of this type is called "single-diffractive" and the region devoid of particles a "pseudo-rapidity gap." Events in which two pomerons are emitted (one each from the antiproton and the proton) and then collide, produce patterns with two forward rapidity gaps due to "double pomeron exchange."

The pomeron is presumed to be a nugget of energy consisting of quarks and gluons, the same stuff the proton is made of, but in a state with the properties (quantum numbers) of the vacuum. It is this feature that allows the proton to remain intact when it emits a pomeron, while it invariably breaks up when it emits a quark or a gluon. Studies of pomeron exchange events may therefore lead to better understanding

of how quarks and gluons are confined within the proton or in what combinations they can escape confinement.

CDF reports a measurement of the ratio of production rates of double pomeron exchange to single diffractive events. The ratio is found to be about five times larger than expectations based on straightforward extrapolations from one-gap to two-gap rates, but in good agreement with recent predictions that provide a unified description of several results on diffraction obtained by CDF and other experiments.
