In January Controls will install a new firewall for ISAC Test Stand. Until then ISAC Test Stand can be used, but it may require an IOC reboot once in while.

Started both ISACT and SOURCES Archivers.

Did a local IOC reboot to cure to white-out. The test stand is now operational.

Rick and John installed the ITE-TM4-SiC#27-HP-SIS-May2012 in the Test Stand. Pumping down.

Did the HV conditioning up to 30kV and started to ramp up the heaters to 580A and 230A.

Today: did a mass scan at 580A on TGHT and 230A on TBHT at 30kV. Found some A/q units discrepancies on the mass scan page. It may be a hall probe problem:  under investigations.

Uploaded the testing file on Docushare: http://documents.triumf.ca/docushare/dsweb/View/Collection-8539/Document-56575

Started the cool down.

Did the HV conditioning.

Heaters conditioning in progress.

The Hall probe is not working: couldn't pass 35.5 units (readback) or 50.16 units (setpoint) at field -3710G.

Tried to turn ON/OFF magnet PS and to reboot Canbus, but nothing worked. Still waiting for E-Fault 6031 to be resolved.

Started cool-down.

Just a quick check at the Test Stand:

1. The system operational (  white out not present ) with TSH:TBHT heating in progress.

2. Started the Archivers: for Source and Optics.

3. Removed bypass on TSH:SV5 since it's not necessary anymore.

4. Currently: TSH:TBHT=107A

Restarted the PC at the Test Stand.

Restarted the Archivers; currently pumping down the separator area.

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.

When turned ON it was not going higher than 3.6A (EPICS/front panel). Kazuya checked the connections at the back and also the EPICS/PLC/PS input/output signals. He compared these values with the similar once of the TSH:TBHT PS (which is also a Xantrex PS 10-600). E-Fault 6275

It turned out to be the connections on the top of the ion source box: the target heater was not connected and the power supply was not seeing the load. Tomorrow we'll check all the top connections, with the corresponding power supplies.

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.

Also TMS:RP2 is very noisy. Talked to Edi D. from vacuum group. He would work on it this afternoon. E-Fault#6282

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.
