Thursday, August 23, 2012, 12:16 : TP1B at speed.

Thursday, August 23, 2012, 12:20 : TP1A timed out. Restarted.

Thursday, August 23, 2012, 12:20 : Turbos at speed. Vacuum at 2.5E-5

Thursday, August 23, 2012, 12:22: Vacuum at 2E-5

Friday, August 24, 2012, 08:26: Vacuum at 3.1E-7

The fuse for both roughing pumps blows when roughing the chamber. With the help from Edi: disconnect the exhaust port on the roughing pump for the first few hundred torrs of roughing. Reconnect and continue.

Seems the roughing pump RP1  pushes air towards the exhaust of RP2 which blows the fuse

 Friday, August 24, 2012, 08:28: Opened water lines. No response in vacuum. Stable at 3.1E-7

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:

Edi will replace TMSRP2 again as it became noisy since yesterday morning. Vacuum should not be affected by the work.

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
