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.

Friday, August 02, 2024, 16:33  data at test number = 7462 can be further visualized using the shared jupyter notebook code.  data taken at anode voltage 260V was disrupted due to a spark derailing a number of optics elements in the beamline. they were soon corrected, but this data was missed.

 Friday, August 02, 2024, 16:34   -   mass scan with  180V 70A      (Argon ON) ---- doesn't seem to be recording background noise well. ie the common background recording artifact is present. records constant numbers instead of numbers in range (1e-13,5e-12). often appears in mass scan image at slants 

Friday, August 02, 2024, 17:07    -   mass scan rerun after switching off argon and pumping down the lines. however, only run from mass 49 down, as the signal above was completely blank

Wednesday, July 01, 2020, 11:50: FC6=6.89e-12A. IG1=2.76e-6T.

FC6 has dropped 60% and the vacuum 15% with the respect to the last set of measurements.

Maybe the mass is not Ar+ but K? Or the decrease in pressure has this large correlation to FC6 magnitude.

Wednesday, July 01, 2020, 12:41: Coil sweep up and down completed.

Wednesday, July 01, 2020, 13:15: Coil sweep completed.

Wednesday, July 01, 2020, 13:22: FC6 and IG1 increasing. Probably due to the coil still at 90A. reducing coil current.

Leaving the cathode hot to continue test tomorrow morning.

Saturday, November 03, 2018, 18:01: Coil sweep from 0-80 A for AV=75,100 completed. Efficiencies of 0.56 % and 0.77% respectively.

Sunday, November 04, 2018, 09:01 : Anode current increased from 56 to around 95 mA overnight under the same conditions. This could indicate a cleaner surface on the cathode and hence a better emission or, the anode cathode distance is reducing fue to the thermal expansion.

Cooling down manually  TBHT to 300 A @ 2A per min.
