CERN’s Large Hadron Collider Successfully Circulates Proton Beams

 

By 10:25 this morning Geneva time, 1:25 a.m. Pacific time, scientists and engineers at CERN had successfully sent a beam of protons all the way around the 27-kilometer circumference of the Large Hadron Collider (LHC), the first of the giant collider’s twin opposing beams. Circulation of the counterclockwise beam followed about three hours later. Thousands of U.S. physicists, engineers, and computer scientists have contributed to the success of the LHC and its major experiments, many of them from Berkeley Lab’s Physics, Accelerator and Fusion Research, Engineering, and Computational Research Divisions. Celebrations have been or will be held in New York, Illinois, and California. Watch for a report on the Bay Area festivities sponsored by swissnex, an adjunct of the Swiss Consulate, in Friday’s TABL. Read the CERN press release here and the US LHC release here.
