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.

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.

Purged the gas lines, turned on the HV and started the heaters for CLT FEBIAD: TGHT up to 580A and TBHT up to 230A.

Started March 31, 2014:

- did the HV conditioning up to 30kV.

April 1, 2014:

- started the Heaters Conditioning. 

Heaters Conditioning finished.

The Power Supplies front panel:

TGHT: 5.56V and 580A

TBHT: 2.23V and 227A

April 2, 2014:

- did a mass scan. NOTE: data is shifted by 10-15%.

plotdump-local-clean.txt_Apr2_14_16-33-19.txt

After the scan finished I found the Test Stand EPICS screens whited-out. Decided with Friedhelm to leave it as it was for the night and to contact Controls next day to reboot it without tripping the heaters and the HV.

April 3, 2014:

Found everything recovered. Except: “SOURCES ARCH IS RUNNING” was red. So, I restarted it. Jane Richards and Friedhelm didn’t do any IOC reboot. Also found that the data from yesterday’s scan was saved (see the previous scan).

Did another mass scan:  plotdump-local-clean.txt_Apr3_14_10-18-13.txt

NOTE: data is shifted by 10-15%.

Cooling down .

HV and Heaters Conditioning had finished. The target was cooled down and it's ready for the on-line installation.

As per Friedhelm the conditioning settings are:

TGHT 580A

TBHT 290A

COIL 80A

ANODE 200V

Ramped up completed:

TGHT 580A/5.683V

TBHT 242A/2.295V (EPICS settings) and 289A/2.29V at the PS

COIL 80A

Current on the Anode = 13.431mA

HV and Heaters Conditioning for SiC#30 was completed Friday, May 23, 2014. The target was cooled down and it's ready for the on-line installation.

The pump failed to pump down below 2 Torr. on Friday 15th E-fault 8680 submitted. Vacuum group will replace the pump today

Edi Dalla Valle from vacuum group replaced the roughing pump TSG:RP1 in the morning. However, the pumping curve showed a leak: see attachment. It was suspected the VCR water line connection between the lid and the base of the target Heat Shield. After venting the chamber found the VCR connection between the lid and the base forgotten finger tight. Tighten it with wrenches and restarted pumping.

 Turned ON the water for the heat shield cooling circuit. Put a lockout padlock on the transformer breaker since Controls work still seems to be underway.

Turned ON the TGHT and ramping it up at a rate of 1A/30sec. Currently it's at 108A.

Temperature measurements in progress for Ta46clone HP-SIS target, wrapped with 3 Ta foil heat-shields . Stopped for today at 360A for the TGHT and TBHT kept OFF.

 Temperature measurements in progress for Ta46clone HP-SIS target, wrapped with 3 Ta foil heat-shields. currently at 496A and the window is OK.

 Temperature measurements ended on Thursday, January 21, followed by cool down over night.

 Pumping down: TS loaded with a LP-SIS container for spectrometer test. 

Started heating up the target container: up to 300A.

Last week: the LP container was heated up to TGHT 580A and TBHT 230A, and cooled down before the weekend. 

Pumping again (LP container in) for one more check. Last check was completed on July 26: up to 400A. 

Vented the chamber today (July 27). 

Did another test over the weekend. Currently the PSs are off and the chamber under vacuum. 

 22:55 Cooldown completed to remove the voltage wires from inside the vacuum box. 

Wednesday, September 14, 2011, 15:39: Vacuum at 1.3e-5 torr 

Thursday, September 15, 2011, 08:59: Vacuum at 2.9e-7 torr. Water flowing and vacuum stable.
