Maico entered the hot cell and re-strung the skipped cable back onto the pulleys this morning. Manipulator is now operational.

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.

Ta#49 has been removed from the south hot cell and placed in the storage vault. It is in pail 146 and in spot 6A.

TM#2 has been moved from the south hot cell to the south west silo.

Argon venting is started

TM2 was disconnected at ITW. 3 water circuits in ITW gave been looped to keep 75 GPM water flow to ITW. HS line was purged at HS. RPG got the water sample.

TM#2 with Ta#49 has been moved from the west target station to the south hot cell.

The ITE is configured to take proton beam.

Weekly update TH schedule for beam schedule 131. See attachments 1,2

A steel plate  is covered on TCS. TCS roughing pump  is started now. The TCS will be pumping down during mini-shut down.

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

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

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

The spent UC#17 has been moved from the south hot cell to the spent target vault. See the attached pdf for details.

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 bundle of electrical checks, first one is the Iglis that failed, the second is the everything passed at the hot cell and the third is a the conditioning station under vacuum.

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

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.
