We have accomplished evaluating the Wien HV, thus determining the reason for vacuum spikes and associated HVPS trips are due to vacuum degradation in the Wiens, induced by magnet coil temperature increase when set above 15 A.

Placing a fan near the H-Wien filter lowered the temperature resulting in stable Wien operation during a 24 hour long test with the magnet coil current set to 15.3 A and Wien electrodes to +/-19 kV required for 90 deg spin rotation.

To find the right impedance, we tried 1 MOhm, 1 kOhm, 500 Ohm, 250 Ohm, and 50 Ohm. We found that 500 Ohm gives the right size of signal (~1.00 V) and does not slow the rise time (e.g., when compared to 250 Ohm).
