Joint Dark Energy Mission Truly Joint

An artist's impression of the SuperNova/Acceleration Probe, one of the formerly competing proposals for JDEM.

Efforts to develop the Joint Dark Energy Mission have changed strategy from competition to collaboration. The teams that were developing competing mission proposals are now called on to join forces and define a combined approach, to be developed and overseen by the Department of Energy and NASA.

A committee appointed by the two bodies, called the Science Coordination Group, will take on the task of determining the scientific aims and technical requirements for the redefined mission. Members of the formerly competing teams now serve on this committee, to select goals that will include observations of supernovae, weak gravitational lensing, and baryon acoustic oscillation.

Kathy Turner, the JDEM program scientist in the DOE's Office of High Energy Physics, said one reason for the change of course was that none of the competing proposals included all the observational approaches NASA and the DOE considered essential. "The agencies have used those concepts to understand what kind of science can be done and for what kind of cost," she said, and will also consider "other concepts that will come forward."

Black Tie: Optional;
Helmet: Required

Riding a bicycle, moped or scooter to and around SLAC is a great way to save fuel. Wearing a helmet while you do so is a great way to protect your safety, and avoid a stop by SLAC security staff.

SLAC requires that you wear a American National Standards Institute-approved helmet any time you are riding a bicycle on SLAC grounds, or a Department of Transportation-approved helmed when riding a moped or scooter. Helmets are available from SLAC Stores when needed for official use. If you enter the SLAC gate without one, security staff will offer you a loaner (small, medium or large)—as their supply of three allows. You will not be allowed to ride on SLAC grounds without a helmet.

In 2006, according to the Web site helmets.org, 67,000 cyclists in the U.S. sustained head injuries; 27,000 of those required hospitalization and 770 cyclists died. More than 8,400 cyclists sustained brain injuries. Approximately 90% of the fatalities occurred with riders not wearing a helmet. 76% of the national fatalities occur in those over the age of 18.

The state of California requires riders under the age of 18 to wear helmets; SLAC rules have no age limit. The SLAC requirement is included in the August 6 update of the SLAC Environment, Safety and Health manual, Chapter 13, section 5.1.2.3. If you have any questions, please contact Simon Ovrahim in SLAC Security (x2551).

Panofsky Prize Awarded to Fermilab Scientist

by Rhianna Wisniewski,
Fermilab Today

When Italian physicist Aldo Menzione recently received a phone call at 2:00 a.m., he expected bad news. But the INFN-Pisa scientist's wakeup call turned out to be the announcement of his selection, along with his colleague, Fermilab guest scientist Luciano Ristori (INFN-Pisa), as a winner of the prestigious 2009 W.K.H. Panofsky Prize in Experimental Physics.

The two collaborators in the Collider Detector at Fermilab won for their leading role in the establishment and use of silicon tracking detectors at a hadron collider. Menzione and Ristori's vision for silicon detectors and their application are now integral to CDF and have been adapted for other particle detectors worldwide. Their insight resulted in a paradigm shift; most detector designs now routinely incorporate these ideas.

Awarded by the American Physical Society, the Panofsky Prize is considered one of the highest honors a physicist can receive. This is the first Panofsky Prize awarded to CDF physicists for their contributions to the CDF experiment.

"We were thrilled," said CDF co-spokesperson Rob Roser about learning of this recognition for CDF. "There are many things about CDF that we feel are innovative. It is nice to be recognized."

SLAC Colloquium Monday

The first SLAC colloquium of fall 2008 will take place Monday, October 20, in Panofsky Auditorium. California climate economist Christopher Busch will address Assembly Bill 32, the Scoping Plan and Western Climate Initiative Design Recommendations. Come for pre-talk refreshments at 3:45 p.m., followed by the colloquium at 4:15.
