Backing pressures TSG:CG1A/B are fluctuating between 0.02 and 0.05 since Sept 17th at ~17h. Expected values <0.01.

 Test stand was off this morning and EPICS controls in "white-out". Controls is looking into it.

Update  13:51:

Controls have reestablished contact with the PLC.

See e-fault 6329

Tried to start the pump from another power outlet with Edi. No luck. Pump will be replaced tomorrow.

 Pump replaced by vacuum group

Did the HV conditioning up to 30kV.

Started the heaters conditioning:

for TSH:TGHT up to 580A

for TSH:TBHT up to 230A

The source was used yesterday for operator training.

Today, I found the source off: the ISAC PLC Status was stopped. Kazuya re-started the PLC. I will re-start the source.

Checked with ISAC Ops this morning and they are not available for FEBIAD training. Turned off the source until next week.

Turned the source back ON. Heaters are ramping up.

On Monday October 1, the HP-FEBIAD source was turned ON again, to complete the operator training. The last session was yesterday and for the time being the ISAC operators can play with the source when time allows, and from the ISAC Control room. For this purpose the source will be kept on this week and also over the week-end.

turbo pumps in source section and all ion gauges off all optics and heaters tripped. Reason unknown.

 Checked the Archiver and the striptool: TSG:TP1A & TP1B tripped on Oct. 10, at 7:53am. Both pumps showed timeout, but the AC breakers were not tripped. Also, checked with MCR: they were no power bumps or cooling water problems around that time. 

Discussed it with Kazuya Negishi from Controls: there were no PLC problems. Kazuya and I would monitor the trips.

Did the HV conditioning for the TiC#3 up to 30kV.

Heaters ramp up in progress.

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

Mass scan file: plotdump-local-clean.txt Nov2 12 13-15-59.txt

The scan was taken at TGHT=573A (read from the PS panel) .

The TBHT = 230A

Started the cooldown for SiC#3.
