Operator: alarcon

Running well. Good runs 14387-14394. All crunching. Problems: 1) During the second half of the shift there were beam problems right after injection that cause the whole detector to trip. 2) R24 was raised to 3800 V and after an hour or so started to trip frequently again.
At around 3:00 PM access to change gas bottles and decided also to work on the beam to get rid of the injection fluctations and get higher injection currents: 200-225 mA. Taylan is taking over. Beam not back yet.
