LHC: Beams are back

From ScienceDaily:

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.

From the BBC: pictures of the happy moment.

CERN’s Twitter feed shows that initial testing complete, and commissioning is now underway. Their tweets have links to info and animations.
