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 |

A Sub D 9 Pin connector on a HV insulator was installed on Port Q of the target box at the teststand. The insulator is leak tested and OK, vacuum is
below 2E-7 T
The feed through is connected (1to1) to the upper 9 Pin connector of the target tray. Since the existing upper 9 Pin connector was damaged from |

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. |
