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.

All TPS optics, with the exception of TPS:Q4 cannot be turned off. E-Fault#6395 for Controls.

Same for the TSG optics: CB1, VCB1 and CBC.

Talked to Evgeniy and Kazuya. Optics are OFF now.

Venting the Test Stand.

TiC#3 will be ready to be removed in few minutes. 

Please note: water is still ON.

Target looks OK. The right leg was a bit much out of center and will be adjusted in the lab.

The torque required to loosen the bolts were measured (from left to right):

Target legs: 48 and 30 in lbs

Tube htr: 25, 30 and 25 in lbs

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.
