Sloooow Shift February 1, 2007

Screens in the Control RoomThe Tevatron is busted. Magnet replacement and ion pump replacement – they have to break part of the ring’s vacuum. This involves warming part of it up to 100K (liquid nitrogen temperatures) which takes a day each way – warm up and cool down. So no beam until late Friday. This sucks because the only two shifts I’ve got on this trip are before Friday afternoon: so no data.

When the accelerator is as dead as this we send some of our shifters home (and keep their phone numbers). So the control room is quite empty. People fall asleep in their chairs. Analysis gets done. The monotony was broken up by only a request from a friend from NIKHEF (in Amsterdam) to reset a local computer. This was nice because it involved a walk outside: it is cold and snowing here. Great way to wake up!
