A short in the anode has developed during the heater ramp up. Increasing the current limit did not cure it. Start heater ramp down to investigate.

Found some water tripping in front of the high voltage power supplies rack from the water lines at the ceiling. Plastic sheets have been put on top of
the racks and MCR has been informed.

The current at the magnet power supply TMS:MB1 shows fluctuations every 1-2 minutes. The same can be seen in the Hall probe read back and in the beam
current at Fc6.

Entry  Friday, July 06, 2012, 11:04, Friedhelm Ames, , , , , , , , source tripped off over night 
A big vacuum excursion tripped the source off at about 1am. The vacuum did not fully recover afterwards only down to about 1.3e-6T. Ne leak has been
closed and vacuum went down to 6e-7T within a few minutes. After the trip the current of the magnet stayed constant. Fluctuations may have been caused
by high voltage sparks.
