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.

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.

An insulated  9-pin D-sub connector was installed on the service cap in port Q (as labeled in ISK4523). The connector mating to the target assembly was placed in the upper slot on the source tray.
