...Beer will save the world Tallmantim...
...Read carefully...
...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 beams. They were also wary of obstacles in the beam pipe which could prevent the protons from completing their first circuit.
Superconducting magnets are cooled down using liquid helium
Mr Myers has experience of the latter problem. While working on the LHC's predecessor, a machine called the Large-Electron Positron Collider, engineers found two beer bottles wedged into the beam pipe - a deliberate, one-off act of sabotage.
The culprits - who were drinking a particular brand that advertising once claimed would "refresh the parts other beers cannot reach" - were never found.
In order to get both beams to circulate continuously around the LHC, engineers have to "close the orbit". The beams themselves are made up of several "packets" - each about a metre long - containing billions of protons. !!!
