B Factory Run 5 for the Record Books
Safety Today: New Permit Required for Drilling and Cutting
Joint USDA-DOE National Renewable Energy Conference Opens Registration
Tuesday - August 29, 2006 |
B Factory Run 5 for the Record BooksThe PEP-II collider and BaBar detector finished Run 5 on August 17 with flourish, showing great promise for the next run. The day before saw many performance records fall by the wayside and long-term goals achieved. The record day was a fitting culmination for 17 months of nearly continuous operation of the B Factory. Ultimately, physics from BaBar is driven by the number of B-anti-B pairs produced in the PEP-II collider. It takes a billion B pairs to produce just a handful of the most interesting rare decays. The rate of B particle production is dependent on luminosity, or how tightly packed the particles in the beam are when they collide. The PEP-II team magnificently satisfied this voracious appetite for more B particles during Run 5. They made significant improvements to luminosity in three different ways: by squeezing the circulating electron and positron bunches harder to produce a smaller transverse cross section, by making them shorter along the beam direction, and by putting more charge in each one.

Joint USDA-DOE National Renewable Energy Conference Opens Registration
The conference will focus on achieving goals outlined in President Bush's Advanced Energy Initiative (AEI), which seeks to change the way we power our cars, homes and businesses through the use of alternative energy sources. The conference will specifically focus discussions on research and commercialization of biomass, wind, and solar technologies. USDA and DOE expect the conference to identify critical pathways, and to make recommendations to help accelerate renewable energy technology development.
