Impedance measured on TGHT and TBHT (~2.5 mOhm and ~2.0 mOhm). Readback on TBHT gives an impedance of ~2.5 mOhm. This is higher than the previous test. Local current on TBHT shows 60A more than the readback at 300A.  The vacuum did not come down as low as usual, which likely means there is a leak.

The Cu-tubing for cooling the Turbo pumps broke off during disassembly. New ferrules could not be located on site and may have to be ordered.

The system will be left under roughing vacuum over the weekend.

Wednesday, January 29, 2014

Cooling for Turbo pumps reconnected.

CuLCW will be shut off tomorrow. Valved off water supply to MB1 and TSG to minimize air into the system. Turbos are off.

• 2x spacers ITD0468 1/8" THK installed to shift the wire scanner screen closer to the wire scanner. (ITD0469 1/16" THK spacers not used).
• Emittance Rig installed. Manually actuated from out -> in -> out position. No interference observed.
• Replaced two insulators on wire scanner screens that broke in the installation process. New insulators kindly donated from ISIS.

The performance of the roughing pump has gradually gone down. Notably after the system has been vented. See attached screenshot from the archiver.

NOTE:

TBHT Power Supply is 600A. EPICS thinks it is 500. Multiply current setting with 1.2 for actual current to the tube.

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.
