Entry  Tuesday, September 20, 2016, 10:32, Travis Cave, South Hot-Cell, Standard Operation, TM4, UC#17, module moved 

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

Entry  Tuesday, September 20, 2016, 11:41, David Wang, ITE, Standard Operation, TM4, , 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.

Entry  Thursday, September 22, 2016, 13:04, David Wang, South Hot-Cell, Standard Operation, TM4, , SHC, TM4 leak check on HS line. 

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.

Entry  Friday, September 23, 2016, 07:49, David Wang, Conditioning Station, Standard Operation, TM4, , TM4 has been moved and connected at TCS 

All TCS and TM4 turbo-pumps were started yesterday. Overnight pumping down is good so far.

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.

Entry  Tuesday, September 27, 2016, 07:30, David Wang, Conditioning Station, Standard Operation, TM4, , TM4 has been disconnected at TCS 

TCS water system and vacuum system are turned  off this morning. The TCS and TM4 are vented.

Entry  Tuesday, September 27, 2016, 09:13, Travis Cave, ITE, Standard Operation, TM4, SiC#34, module moved 

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

Entry  Wednesday, September 28, 2016, 13:43, David Wang, ITE, Standard Operation, TM4, , 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.

Entry  Tuesday, October 04, 2016, 09:18, David Wang, ITE, Standard Operation, TM4, , 5 Shielding blocks have been transferred from ITW to ITE. 

The ITE is configured to take proton beam.

Entry  Thursday, October 20, 2016, 14:17, Anders Mjos, ITE, Repair, TM4, SiC#34, HV enclosure inspection SiC#34_Dose_Map_Target_Pit.pdfSiC#34_Dose_Measurements.xlsx

 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.

Entry  Tuesday, November 01, 2016, 14:53, David Wang, ITE, Standard Operation, TM4, , 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.

Entry  Tuesday, November 01, 2016, 14:54, David Wang, ITE, Standard Operation, TM4, , 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.

Entry  Tuesday, November 01, 2016, 14:58, David Wang, South Hot-Cell, Standard Operation, TM4, , 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.
