SLAC Today

Wednesday - October 3, 2007

The PEP-II accelerator has reached a milestone, delivering enough particle collisions for the BaBar detector to observe 500 million pairs of B and anti-B particles.

PEP-II Delivers Half an Inverse Attobarn to BaBar, With More to Come

Thanks to a steady push during the course of eight years, the PEP-II accelerator has now delivered double the amount of data originally expected when the BaBar experiment first started up in May of 1999.

Between then and September 4, 2007, when Run 6 concluded, PEP-II has generated a remarkable half an inverse attobarn of integrated luminosity—a measure of the number of particle collisions in a given period of time. This corresponds to 500 million pairs of B and anti-B particles, whose decays have yielded major discoveries this decade. The sheer quantity of data is reshaping the kind of physics that can be investigated.

PEP-II's achievement is a testament to hard work, as well as continual upgrades and adjustments to a machine built with the capacity for future improvements. The accelerator now regularly operates with four times the luminosity, or collision concentration, it was designed to deliver. Higher luminosity translates into more accurate results and the ability to find otherwise unobservable physics, such as matter–antimatter asymmetry in rare "penguin" type decays. Read more...

Gail Fong: Renovating Facilities Information

Behind every facilities operation at SLAC is a multitude of information that communicates what to do, where to do it, and how to do it efficiently. As the lab's facilities operations increase in number and complexity, it has become imperative to reinvent the way the Facilities Department stores and shares this information.

Spearheading this advancement is Gail Fong, the new manager of the "Facilities Information Group," formerly known as the "Maintenance and Information Management Group." Fong, who arrived at SLAC 2 months ago, will manage and coordinate the facilities service desk, facilities computer system support, system administration, preventive maintenance program and facilities maintenance reporting.

One of her major responsibilities will be the implementation and management of SLAC's new computerized maintenance management system, known as FAMIS (Facilities Asset Management Information System). FAMIS will integrate many of the lab's facilities operations into a single software suite, providing a unified database for tracking equipment, work order history, work order costs, and maintenance requests. "This will allow technicians to have the necessary information in the field, and to keep customers informed about their work requests," Fong said. Read more...

Pief, Remembered

Whether they knew him for five minutes or for 50 years, it seems that everyone who encountered Pief Panofsky has at least one story about him—he was just that kind of unforgettable person. As a way of celebrating and remembering him, the SLAC Archives and History Office would like to collect any of your "Pief Stories" that you would like to share, be they funny, serious, casual, profound, or somewhere in-between.

On the Pief Stories website, please tell us a little bit about yourself, how you met Pief, and then tell us your particular Pief Story. The SLAC Archives and History Office will gather these together to share with the community as a lasting memorial to SLAC's first Director, the original, unique and irreplaceable W. K. H. "Pief" Panofsky.

Use Energy Wisely

When selecting office task lighting, consider safer, more efficient ENERGY STAR lamps over popular halogen lamps which have been known to be a safety concern, according to the U.S. Consumer Product Safety Commission. While halogen lamps are relatively inexpensive to purchase, they are relatively more expensive to operate, and create a lot of unnecessary heat in summer, adding to cooling costs.
