Did HV conditioning up to TSG:BIAS=30kV, TSH=EE=-600V

Turned off the HV for Kazuya to check the connection/output of the TSG:TGHT Xantrex power supply.

Tested the power supplies and locked up the HV cage.

Turned on the HV: 30kV.

Tomorrow we'll start up the heaters: 580A for the target and 280-300A for the tube.

Friedhelm checked the voltage across R4 from ISK4563D-rev2.pdf. It shows 50 kOhms with the power supplies off and everything connected according to the drawing. With the Anode PS On and set at 20V, we could see the same readback on EPICS and on the meter.

Then started the heater ramping: auto ramp 2A/min.

We'd be watching the vacuum carefully during this process. Also the setup is such that:

- the target and tube heaters are only incremented if the vacuum is less than 5e-6Torr

- and if the vacuum exceeds 2e-5Torr the last increment of the target and tube heater is backed off.

Pierre asked for the 2e-5Torr limit to be changed to 8e-6Torr.

Anders asked to stop the heating at 500A to take a temperature measurement.

Raising the target heater from 500A to 580A.

Did a mass scan at TGHT=580A & TBHT=280A:  Plotdump-local-clean.txt Aug29 12 19-53-16.txt

Did another mass scan at 280A for the ionizer:

Ramping up the TBHT from 280A -> 290A

And from 290A -> 300A:

Started the cooldown.

Turned off the HV and the optics in the first section. Couldn't turn off the optics in the second section: left a message for Evgeniy.

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.

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.
