Particle beams are once again zooming around the world’s most powerful particle accelerator—the Large Hadron Collider—located at the CERN laboratory near Geneva, Switzerland. On November 20 at 4:00 p.m. EST, a clockwise circulating beam was established in the LHC’s 17-mile ring.

An international collaboration of scientists today sent the first beam of protons zooming at nearly the speed of light around the world’s most powerful particle accelerator-the Large Hadron Collider (LHC) located at the CERN laboratory near Geneva, Switzerland

Journalists and guests are invited to witness the start-up of the Large Hadron Collider live and in real time at the LHC Remote Operations Center at the Department of Energy’s Fermilab, in Batavia, Illinois in the early morning hours of Wednesday, September 10.

On September 10, scientists at the Large Hadron Collider will attempt for the first time to send a proton beam zooming around the 27-kilometer-long accelerator.

Batavia, Ill. – Early yesterday morning (Jan. 22), scientists of the U.S. CMS collaboration joined colleagues around the world to celebrate the lowering of the final piece of the Compact Muon Solenoid detector into the underground collision hall at CERN in Geneva, Switzerland. The near completion of the CMS detector marks a pivotal moment for the international experiment, in preparation for the start-up of the Large Hadron Collider this summer. CMS has approximately 2,300 international collaborators. Supported by the Department…

Scientists of the U.S. Department of Energy/Office of Science’s Fermi National Accelerator Laboratory and collaborators of the US/CMS project have joined colleagues from around the world in announcing that the world’s largest superconducting solenoid magnet has reached full field strength in tests at CERN, the European Particle Physics Laboratory.
