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.

 Wednesday, November 14, 2018, 17:53: When opening the Neon valve, the vacuum reached ~1e-5 T and the test stand tripped. Ion source off, high voltage and some of the optics as well. Leaving the test stand as is.

In the last mass scan, I add up the highest peaks above 1e-9A  and the values was roughly 7e-8A. Switching the gain to 94uA in FCO shows 8.32e-8 A. This seems a better reading than before.
