Leak found on the Ne supply line. 1E-4 - 1E-5 range. Replaced fittings. Had to use one brass piece. Leak rate 6E-9 (probably due to Ne response). No response to He.
Leak rate around low E-8 with regulation valve open.
When closing the HV rack, an air supply leak developed on the manifold for the valves. Shut off air supply. Valves still operational, but requires opening up air supply to actuate.

With the help of Rick, the leak was fixed.
The vacuum pump for the gas lines was removed for repairing the leaking hose. |
