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.

Carla, Fernando, Matt K.

Friday, May 31, 2019, 12:33  Using Brad's tuning values we see a nice peak at the first set of wire scanners on the y axis but nothing on the x axis. Using CB2, went from 200V to 900V in steps of 100V and saw nothing on the x axis. This seems to indicate x axis scanner is broken. Proceeding without x axis readout. Also tried with CB1 steerers, same effect.

Wednesday, June 19, 2019, 07:10: IV4 Closed.

Wednesday, June 19, 2019, 07:12: Gas lines & Sources / power off.

Wednesday, June 19, 2019, 07:15: RGA off.

Wednesday, June 19, 2019, 07:16: IG1 & Turbo pumps off.

Wednesday, June 19, 2019, 08:35: Purging / venting.

Inserted a used (heating) LP-FEBIAD target with a basic heat shield assembly with no end plate foil on the window side to observe heating. The P2N Coil / TGHT connections were added.

Test whether the TS connections are affecting the P2N heating or if it's the P2N target itself.

-Heat the TGHT only, observe, then ramp down.

-Heat Coil only, observe, then ramp down.

-Heat TGHT w/ Coil, observe, then ramp down.

Note* Heating should be even across the target. Elog & take pictures.

NO HV ALLOWED!!!!
