The wiring on the top of the test stand was burned, see entry 737.

Probable cause of this is as follows:

Coil lines are connected by a wire to HV common, the 9-pin feedthrough etc to maintain same voltage on all the insulator tops. This is also directly connected to the extraction electrode spark gap. When this sparks, it momentarily changes the potential in that line (normally HV common) which then can make this path the best route for current from the coil to return to ground.

See attached diagram.

Best solution to this problem is to disconnect the high current section from the low current section, and attach each separately to HV common.

Other possible improvements to wiring:

1. Remove jumpers between positive coil lines (and neg. coil lines) since these feethroughs are physically connected by the copper pipe.

2. Add a resistor to the jumper between coil - and TBHT - since this will eliminate all possibility of current flowing between the two.

3. Add a resistor in line where the high current section is connected to HV common to avoid possibility of current going through jumpers.

Attached is a recent list of Ta targets with their extracted ions peaks.

 When the target was removed from the test stand it was discovered that the custom designed insulator stand-off (ITD0400 made from Mycroy 1100) had swollen and become discoloured in the area exposed to "heat shine" from the target oven. See attached pdf for photos of the insulators.

The heat shield lid was opened up and the target temporarily removed to replace the two insulators that had failed. These were replaced with the commercially available glazed steatite stand-offs. The target had some marks from the insulators which was cleaned with acetone and methanol.

After replacing the insulators, the target assembly was assembled, leak checked and a new electrical check was performed.
