After lots of delays CERN has released a positive report yesterday. The LHC (Large Hadron Collider) circulated two beams simultaneously for the first time, allowing the operators to test the synchronization of the beams and giving the experiments their first chance to look for proton-proton collisions. I assume the Black hole fear has died out because of all the delays.
"It's a great achievement to have come this far in so short a time," said CERN Director General Rolf Heuer. "But we need to keep a sense of perspective – there’s still much to do before we can start the LHC physics program."
These developments come just three days after the LHC restart, demonstrating the excellent performance of the beam control system.
