After long power outage, everything is off except the roughing pumps. Two turbo pumps (TMSTP2 and TSGTP1B) have shown fault due to timeout, only
TSGTP1B could be reset, while TMSTP2 is still showing this fault

thermocouple is reading 224C, which is definitely colder than the temp from visual insepection, reading may be corrupted from contact to Heatschield

The anode PS is turned off and connected to HV common.
the Target is connected to a -18V PS at the center support (Feed through A) for a on/off test of ion suppression
NOTE: there is a shortcut target <--> HV gnd, most propably due to the thermocouple touching something after pumping.
