- Cu-gaskets used for leak checking target had a leak rate of about 10-8 10-9 atm cc/sec. Replaced with silver plated SS gaskets and no leak detected above 10-11 atm cc/sec.
- The target can not hold high voltage when it is sitting on the jig. The insulator on the jig have reduced resistance over time (less than 1 G Ohm). All high voltage tests passed when target is tested not sitting on the jig.
- Target is now in the test stand and pumping down.

After the test-stand, the extraction electrode showed some electric arcing mark, but no solid deposits were found. (see attachment#1: EE_after_teststand.jpg)
See attachment for the target specification. |
