|
The TSH:TGHT stopped at 263.7A, but the setpoint is still ramping (now at 421A). The voltage is set correctly: have 6.238V setpoint and 4.386V readback.
The reading on the Power Supply shows 418A. Through the window the target assembly looks at high temperature. The readback on Epics seems stuck.

Prepared the Test Stand for Controls to investigate E-Fault#6389.
Evgeniy increased the current limit on the power supply TSH:TGHT from 2 rotations to 7 rotations, after talking to Ray Dube. |

|
Evgeniy and Kazuya investigated the problem with TSH:TGHT readbacks and they came to the conclusion that the PS is faulty, and the PLC reads correctly
the signal sent by the PS. Kazuya is redirecting the E-Fault from Controls to PS.
Ray Dube estimated few weeks (4-6) to send the PS offsite for repairs. This needs to be scheduled. For the time being, one can use the Test Stand |

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. |
