Anders Mjos | ITE | Repair | TM4 | SiC#34 | HV 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. |

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. |
