Project Accounting a Success | ||
| ||
|
Invited by Associate Director Bruce Chrisman, about 60 people gathered on
Wednesday in the Kuhn Barn to enjoy a special luncheon. The group celebrated
the successful implementation of the Oracle Project Accounting system. In
April, the smooth transition to the new system affected all employees since
Project Accounting required the replacement of budget codes with project and
task numbers. In early October, the new system passed its final "test" as
the Business Services Section produced all end-of-FY2003 reports for DOE on
time and without significant problems. "The help desk has received very few
phone calls," said Bob Willford, who manages training and administrative
services for the Business Systems Department.

MuCool celebrates new buildings | ||
| ||
| "On time, on budget, no injuries" was the summary by Milorad Popovic, who managed the construction of two buildings for the new MuCool laboratory. "We used less than one percent of the contingency money." On Tuesday, project participants celebrated the completion of $1.5 million lab, which is located at the southeastern end of Fermilab's Linac. The construction was paid for by the international Muon collaboration. The MuCool laboratory will host infrastructure for accelerator R & D. Soon physicists will begin to test beam-cooling capabilities of absorbers and RF cavities that some day might be used to create compact muon beams. "By Christmas we will fill the first liquid-hydrogen absorber," said Steve Geer, spokesman of the Muon Collaboration. "In about a year we will receive a 201-MHz cavity built at LBL. By then we want to be ready to test it." | ||

From Science Daily, October 14, 2003 Grid Technology Helps Astronomers Keep Pace With The Universe "Intelligent Agent" computer programs are roaming the Internet and watching the skies. It may sound like science fiction, but these programs, using Grid computing technology, will help astronomers detect some of the most dramatic events in the universe, such as massive supernova explosions. read more |

Matter-Antimatter Mixing at CDF | ||
| ||
|
Every particle has its own antiparticle in a well-established
symmetrical pairing. In some cases, this pairing allows the
transition of matter into antimatter
and vice versa, through
quantum virtual states (i.e. states which can exist only for
a short period of time according to the Heisenberg uncertainty principle).
This transition is technically referred to as "mixing". The study of this
phenomenon allows physicists to infer the properties of the virtual states
that enable the mixing itself. The results will either confirm or refute
the predictions of the Standard Model.
At CDF we've measured the probability of a B meson to turn into its antimatter partner, the anti-B meson. (Every B meson contains one b-antiquark and one d-quark. It exists for a tiny fraction of a second before decaying into other particles.) Produced by proton-antiproton collisions, the B mesons decay and leave signals inside the CDF detector. We infer the B-mixing probability by looking at the decay products of the B-mesons. We've found a mixing probability larger than the value observed in similar measurements performed with electron-positron collisions at the LEP collider (CERN). Although the CDF result could be tantalizing given its possible interpretation in terms of new physics, we are still cautious. The higher value we measure may be based on a yet-to-be-understood difference in the production environment (p pbar versus e+ e-). | ||
