|
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. |

Gas line vacuum pump reinstalled after fitting was modified to receive a standard swagelok connector. The vacuum line was plumbed using 1/4" copper tube (not Stainless) for the the ability to flex and manipulate the line for pump removal and and insertion. |

The ramp up finished.
I have 3.35E-6 Amp out of the source on FC0.
Vacuum 4.3 E-7 T increase Coil current to 40 A. No effect on vac.
Increase coil to 50 A. Vacuum still good.
I will continue from home.. |

|
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. E-Fault for Controls 6389 |

|
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.
I turned on the HV at 30kV and started the Auto-ramping. |

|
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 with the PS setpoints, displayed on its front panel, as a reference. |
