Thirty-Three Fermilab Employees Receive Employee Performance Recognition Awards
EPRAs
33 employees received Performance Recognition Awards last Thursday. (Click on image for larger version.)
On April 14, thirty-three employees received Employee Performance Recognition Awards. Following a luncheon at Chez Leon, Fermilab Director Michael Witherell handed out the awards. "These awards recognize the fact that people do things that make a big difference," Witherell said. "These are the people who make the lab run."

The incoming Fermilab director, Pier Oddone, also attended the luncheon. With slightly less than two and a half months left to Witherell's term as the current Fermilab director, he concluded the ceremony with some parting remarks. "This will be the last time I will have the opportunity to hand out these awards," he said. "Fermilab's greatest legacy is the quality and the commitment of the people who work here. Thank you very much for everything you have done."

Fermilab Art Gallery Hosts Artist Reception Tonight
Employee Art Show 2005
The 2005 Employee Art Show will be on display until May 31. (Click on image for larger version.)
The Fermilab Art Gallery will host an artist reception tonight on the 2nd floor crossover from 5:00 p.m. to 7:00 p.m. for "My Artistic Side - an Employee Art Show 2005." From photographs of buffalo to turtle purses to a functioning fountain, this year's exhibit showcases 37 talented employees.

"The arts not only make for a more stimulating and creative work environment, but they have a direct and positive impact on the employees," writes Fermilab Art Gallery Curator Georgia Schwender on the show's Web site. "By participating in 'My Artistic Side-an Employee Art Show,' we recognize the creativity of the employees."

The Employee Art Show will be on display until May 31. All employees and users are invited to attend the artist reception tonight, which will also feature a performance by the Fermilab Singers. You may be impressed with how creative your co-workers can be.

Department of Energy Press Release, April 19, 2005
Energy Department Awards Contract to the University of California to Manage and Operate Lawrence Berkeley National Laboratory
WASHINGTON, DC -- The Department of Energy (DOE) has awarded a new five-year contract to the University of California to manage and operate its Lawrence Berkeley National Laboratory (LBNL). The award is the result of the first competition of the management and operating (M&O) contract for the laboratory since its inception.

The value of the new five-year contract is an estimated $2.3 billion. Berkeley Lab's $469 million annual budget is funded by the department's Office of Science, other DOE programs, as well as other government agencies and private industry.

"Because of its outstanding work, including 10 Nobel Prizes won by its scientists, Lawrence Berkeley Laboratory has helped ensure U.S. scientific leadership for more than 60 years," Secretary of Energy Samuel W. Bodman said. "This contract award will allow LBNL and its outstanding researchers and staff to seamlessly continue their work as they set new standards of scientific excellence."

Women explore the frontiers of physics
Einsteinís intellectual heiresses add to his legacy
By Alan Boyle
Around the world, the 21st-century successors to Albert Einstein are delving into the mysteries surrounding ghostly neutrinos, rolled-up dimensions and clouds of super-cooled gas that can freeze a light beam in its tracks.

And plenty of those successors are women.

Their work on the frontiers of physics runs counter to the claim that women might be innately less suited for math and science ó a hypothesis that was most recently, and provocatively, raised by Harvard President Lawrence Summers in January. Time magazine framed the issue in the form of a question: "Who Says a Woman Can't Be Einstein?"

CDMS Sets Best Limits
In Dark Matter Search

CDMS
This plot shows the regions of parameter space that have been ruled out by a given experiment. For example, under standard assumptions for the galactic halo and the interaction of WIMPs with nuclei, WIMPs with mass and cross section above the solid blue curve can be excluded at the 90% confidence level by the CDMS-II data taken at Soudan. The red-colored region corresponds to the claim of a signal by the DAMA collaboration, which is clearly incompatible with CDMS for this set of assumptions. The other colored regions illustrate where different Supersymmetry models provide WIMP candidates, or alternatively, can be ruled out by dark matter null results (more details). (Click on image for larger version.)
Scientists of the Cryogenic Dark Matter Search (CDMS-II) presented new data at the American Physical Society meeting in Tampa on Sunday, April 17, peering with greater sensitivity than ever before into the suspected realm of the Weakly Interacting Massive Particles (WIMPs). The sighting of WIMPs could answer the double-mystery of dark matter on the cosmic scale of astrophysics, and of supersymmetry on the subatomic scale of particle physics. The results were presented in an invited talk by Richard Schnee of Case Western Reserve University, followed by a sequence of contributed talks by CDMS graduate students Michael Attisha of Brown University, Walter Ogburn of Stanford University, Angela Reisetter of the University of Minnesota, and Raymond Bunker of the University of California, Santa Barbara.

the new data Sunday
in an invited talk at
the American Physical
Society meeting in
Tampa, Florida.

The accompanying mass versus cross-section plot shows the results (black curve) from 2004 with the first six-detector tower [PRL 93, 211301 (2004) and astro-ph/0405033]. Those limits were then the best in the world by a factor of four over EDELWEISS (brown curve) and ZEPLIN (green curve). The combined 2004 and new preliminary 2005 result from CDMSII (blue curve) represents an additional factor of 2.5 improved sensitivity, with two towers containing twelve detectors. This result is a full factor of ten better than EDELWEISS and ZEPLIN, meaning that, while no signal has been seen, CDMSII is exploring virgin territory for dark matter in the form of weakly interacting massive particles.

The lightest supersymmetric particle is an excellent candidate in many models, as shown by the colored regions in the plot background, and the new CDMSII results exclude many SUSY models as well as the signal claimed by DAMA (red closed region). CDMSII is part of the newly-organized Particle Astrophysics Center at Fermilab. A paper describing the scientific results will soon be submitted to Physical Review Letters.
