No leak detected on either He-detector (connected directly to Service Cap) or on RGA. See attached screen shots.
A vacuum increase (air only on RGA) was seen when de-pressurizing circuit I. |

Wednesday, January 07, 2015, 09:31, Anders Mjos, Conditioning Station, Development, TM2, , High Voltage Conditioning
|
No Source Tray installed. Loop on cooling circuit D. All other circuits blanked off.
Voltages stated below are set point voltages. These corresponds reasonably well with the local read backs on the power supplies. The read back
voltages in EPICS are somewhat lower. |

|
See e-log entry for ITE for details. The copper bars have not been removed. They
can be used for testing the new power supplies.
Local measurement was done by Ray with a voltmeter. The voltmeter was consistent with EPICS readback and local readback on the power supplies. |

|
Tuesday, April 28, 2015, 11:09, Anders Mjos, ITW, Maintenance, , , Resistance measured of TGHT and TBHT lines to ITW
|
The new TBHT and TGHT power supplies were brough up to high current; 350 A and 420 A respectively. The TGHT power supply was limited by PLC to 420 A.
The resistance calculated for both the TBHT and TGHT copper lines from the electrical services room to the ITW pit was 1.35 mOhm. See attached spreadsheet
for details. |
