1) When opening FC0 a spike occurs in the vacuum on IG6 & IG1 (though not as bad). This spike trips off the optics, and if left unchecked, will trip off the TGHT / TBHT / Sources.

2) RGA is also unresponsive

3) Leak rates also noted in the Ar gas bottle for the FEBIAD source. Previous trips had occurred in the most recent FEBIAD tests.

Optics tripped during FC0 removal. Vacuum spikes also detected on IG1 & IG6. No response on RGA.

The small leak in SV5 allows the lines to 'pump down into the mTorr range, however upon opening the line to the pump, the line pressure increases.

Tuesday, November 20, 2018, 10:44: Opened valve to the small pump. Small vacuum spike noticed on IG1 up to 5.02e-07T after reopening line to the small pump. Convectron gauge spiked to 3.25 Torr from 18.6 mTorr.

Tuesday, November 13, 2018, 16:44: The anode drain current has increased 17mA since 11:23 am, however FC0 is still decreasing. I will keep monitoring to see if the behaviour of the anode drain current continues once FC0 has stabilized. If the anode drain current keeps increasing maybe we will observe the same failure from the previous FEBIAD.

FM

Wednesday, November 14, 2018, 11:02 FC0 is stable but the anode drain current is still increasing and now is at 85 mA. It started at ~52mA. From the strip tool it seems to be a 2-hour period where the anode drain current is stable.
