TM#4 has been moved from the east target station to the south hot cell

  1356   Tuesday, September 20, 2016, 11:41 David WangITEStandard OperationTM4 TM4 has been disconnected in ITE.

TM4 has been disconnected in ITE. No water line purge on HS and 3 water circuits are looped after disconnection. The HALCW system resistivity is stable before and after this disconnection.

Chad and I leak checked the TM4 HS line after new target installation. base leak rate:0.0Xe-9 atm.cc/sec.  No response on LD during the leak check. The line is leak free so far. It will be helium pressurized at TCS  late.

Conditioning by ISAC operations

Saturday, September 24, 2016, 11:15: RGA on for heater conditioning. (kept off during HV conditioning)


Sunday, September 25, 2016, 07:44: TGHT and TBHT voltage jumps during heater ramping. Likely contact between target and heat shield. Contacted ISAC operations and asked to abort ramping at current values. TGHT/TBHT 500 /270 A


Monday, September 26, 2016, 08:22: ISAC operations resuming ramping to 550 A. Corrected TGHT voltage at ISAC TS was ~6.2 V at 580 A. Expected voltage at TCS would then be 6.2 + (3.4+2.9)E-3*580 = 9.9 V. Limit set at 9.5 V.

Monday, September 26, 2016, 09:09: Increased TGHT voltage limit to 9.6 V to allow it to reach 550 A.

Monday, September 26, 2016, 10:17: Voltage limit increased to 10.2 V which allowed the current to go to 575 A


Tuesday, September 27, 2016, 08:08: Conditioning complete. Ran at 575 / 270 A and 47 kV for about 1 hour. Conditioned cold to 49 kV.

TM#4 with SiC #34 has been moved to the east target station.

  1365   Wednesday, September 28, 2016, 13:43 David WangITEStandard OperationTM4 TM4 has been connected at ITE

All ITE turbo pumps have been started since yesterday afternoon. The ITE and TM4 pumping down is good so far.

  1368   Tuesday, October 04, 2016, 09:18 David WangITEStandard OperationTM4 5 Shielding blocks have been transferred from ITW to ITE.

The ITE is configured to take proton beam.

  1374   Thursday, October 20, 2016, 14:17 Anders MjosITERepairTM4SiC#34HV enclosure inspection

 The HV enclosure and module connections were inspected by David and Anders on Wednesday 19th in an attempt to find any HV problems causing the high leakage current. One cable was cable tied to a copper conductor in the chase. Some small pieces of loose material were removed. No obvious problems could be detected.

  1385   Tuesday, November 01, 2016, 14:53 David WangITEStandard OperationTM4 TM4 was disconnected at ITE

TM4 was disconnected at ITE this morning. It was moved to SHC  after. No alpha alarm issue has been happened during and after move. The ventilation pumping down procedure on ITE was fulfilled during the move.

TM4 was disconnected at ITE this morning. It was moved to SHC  after. No alpha alarm issue has been happened during and after move. The ventilation pumping down procedure on ITE was fulfilled during the move.

  1387   Tuesday, November 01, 2016, 14:58 David WangSouth Hot-CellStandard OperationTM4 SHC, TM4 leak check on HS line.

Chad and I did a leak check on TM4 HS line with new Ta target installed. Base leak rate 0.0xE-9 atm.cc/sec. base pressure 0.0XE-4.   splayed 2 helium to each VCR joints and did 10 seconds helium flush. No response on LD during the test. The HS line is leak free so far. It will be helium pressurized at TCS later.
