At 1:06 p.m. Central European Summer Time today, the first protons collided at 7 TeV in the Large Hadron Collider. These first collisions, recorded by the LHC experiments, mark the start of the LHC's research program. For more information about this milestone event, the LHC's physics potential at 7 TeV and American participation in the project, read the press releases below. You can also tune in live to CERN's LHC First Physics webcast before 12:15 p.m. Eastern time (6:15 p.m. CEST) today. Here in California, SLAC's ATLAS team has invited everyone at the laboratory to view a replay of the collision attempt in Kavli Auditorium from 9 to 9:15 a.m. today.

Physics Begins at the Large Hadron Collider

Batavia, IL and Upton, NY – The Large Hadron Collider has launched a new era for particle physics. Today at 1:06 p.m. Central European Summer Time (CEST) at CERN in Geneva, Switzerland, the first particles collided at the record energy of seven trillion electron volts (TeV). These collisions mark the start of a decades-long LHC research program, and the beginning of the search for discoveries by thousands of scientists around the world.

"Todayis first 7 TeV collisions are a great start for LHC science," said Dr. Dennis Kovar, Associate Director of Science for High Energy Physics at the U.S. Department of Energy. "We eagerly anticipate the work of the worldis physicists as they begin their search for dark matter, extra dimensions, and the ever-elusive Higgs boson." Read more in Symmetry Breaking...

Final Deadline for 2009 GERT Dosimeters Tomorrow

from the Radiation Protection Department

If you were issued a GERT dosimeter during 2009 you must return it by tomorrow, March 31, to ensure that any exposures are detected. Take a moment to check your GERT dosimeter: Does it have a green stripe down the middle? Then it is overdue. Another way to check is to remove it from its holder. If you see the date 01/01/2009 at the top of the dosimeter, it is overdue. Immediately return any such dosimeters to Mail Stop 84, attention: Radiation Protection.

New Petty Cash Hours April 1

by Laurie Escudero

Effective April 1, the Petty Cash window will be open every morning from 10 to 11:30, and will no longer be open in the afternoon. Those who are unable to get to Petty Cash during these hours may call or e-mail to make an appointment. In addition, the Travel, Payroll and Accounts Payable Departments will be open each morning from 10 to 11:30 for travel reimbursement, special payments and off-cycle manual payroll check pick-up at the respective office. For those who are unable to pick up checks during these hours, please e-mail the appropriate department to arrange a pick-up time.
