Steve Myers, head of the accelerator and beam department, said: "There are on the order of 2,000 magnetic circuits in the machine. This means there are 2,000 power supplies which generate the current which flows in the coils of the magnets."
If there was a fault with any of these, he said, it would have stopped the beam. They were also wary of obstacles in the beam pipe which could prevent the protons from completing their first circuit.
I feel safe knowing the greatest minds on the planet are on hand pulling the empties out of the worlds largest Proton collider. cheers fellas
