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.

The sheet metal panel covering the NHC/SHC feedthrough port was removed today using a slide-hammer to pull out the concrete anchors (this oversized panel would have interfered with the NHC partition wall).  50cpm was found on the inside of the panel, 100cpm on the NHC side lip of the feedthrough, and 350cpm on the face of the shielding bricks in the feedthrough.  Various dimensional measurements of the feedthrough were taken which will be added to the partition wall Solidworks model (IRH1609).  The panel was bagged for disposal and a temporary 20"x20" panel was put over the feedthrough and secured with duct tape.  A permanent panel with anchored supports that is compatible with the NHC partition wall will be designed and installed at a later date.  A swipe of the NHC walls and floor picked up 30cpm after completion of the job.

After blue insulators replacement, TM3 service cap are leak checked. LD base leak rate 0.0xe-9 atm.cc/sec. I sprayed lots helium on all blue insulator seals. No leak has been found. Double checked them again, and got same result. All other seals on top of TM3 also have been checked. They are leak free. OVEN, TUBE, MSP, COIL, and EE water lines are pressurized with 70 psi helium for 3minutes each. They are good also.
