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.
