During target removal on Wednesday October 12th, the left target heater conductor bolt (ITD0058) could not be removed. The bolt was found to be stuck in the threads (keensert) of the TGHT conductor block (ITA0583). In the process of attempting to remove the bolt, the conductor insulator (ITD0054) cracked (ref assy ITD0052). To allow increased torque to be applied and support the conductor block, a clamping jig (ITD0612) was designed and fabricated. The jig was assembled and it's function tested on the ISAC Test Stand on Friday 14th. On Monday 17th the bolt could be removed using the clamping jig and a socket wrench with an extended handle.

The threads on the removed bolt was damaged. A new set of bolts were therefore prepared and a tap was run through the keensert to restore the threads. The threads in the conductor block was tested and found to be OK using a new bolt.

The spent target could now be removed. Unfortunately the right manipulator failed during installation of a new conductor insulator, which forced the repair of the insulator and installation of the new target (SiC#35) to be postponed until the manipulator can be repaired.

Broken cable has been replaced however a cable has hopped some pulleys inside. After two hours in cell the job was stopped with cables still off pulleys. Alternate tooling will have to be made and the job will continue Monday.

 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.
