Re: what exactly is done during precycling?

IMHO precycling = cycling, which is process to reset magnetic memory of the superconducting magnets. They keep tiny piece of the history of their magnetization in the hysteresis curves if I can understand it well. That's why for the perfect reproducibility of the next settings it is necessary to mag...

0830 Info: 02:00 –03: 00 : ALICE : beam on the TED The obvious major work is Hump hunting and other fine tuning of the beam. Not sure what ALICE: Beam on the TED means - the TED being in would imply no beam in the LHC, so ALICE may be turning on their magnet or similar. I think, they are measuring ...
