A large (water?) leak opened up with target close to max temperature. Water lines were pressurized in an attempt to identify the leaky line. The test yesterday were not conclusive and was repeated this morning with no He response. The vacuum did not improve over night.

With the leak detector pumping on the left coil line, a large leak could be confirmed at the soldering site.

NOTE: COIL PS is a 100 A supply, thus actual COIL current is 0.5x COIL set point.

Changed the FEBIAD connector blocks to have copper tubes exit below the block. Extended ANODE wire to allow it to be wrapped around Cu-tubes and keep it further away from the GE lines.

 Friday, April 6, 2018, afternoon: Due to inconsistencies on EPICS, Carla and I Change the Anode power supply to local in order to monitor the leakage current with a multimeter.

Monday, April 9, 2018, afternoon: TBHT@350A and TGHT@550A 

PS went current limited at AnodeBias=300V and show 3A on the PS Screen, the multimeter read the same.

Ramp down to 0 V 0A on PS. PS shows 0.01V

PS goes to limited current even at 2V.

Tuesday, April 10, 2018, 09:10: Problem persists even at lower TBHG (330A). 

The output cable was removed and the power power supply seemed to behave better. This could mean that there is a short inside the unit, in the past the anode cable had melted into the cup.

Planning to ramp down the TBHT and see if the behaviour remains. If it does, I would ask to remove the unit for inspection.

Tuesday, April 10, 2018, 09:32 : Ramping down TBHTH to 250A

Tuesday, April 10, 2018, 13:07 : Same behaviour. Cooling procedure started to see if the issue is still present, anf if it does remove unit for inspection

Adjusting Emittance parameter for more precise scan

Wednesday, July 11, 2018, 15:37 Cathode is still "cold" , at 325A and 250V the anode current is 15 mA. The way to obtained more current and to have better emittances readings is to increase the tbht current

Wednesday, July 11, 2018, 15:39 TBHT=325, TBHT RB =339.1A, TBHT PS=330A. Increasing TBHT to 335A. Where TBHT RB is the read back value. TBHT PS is the value display on the Power Supply

Wednesday, July 11, 2018, 15:46 tbht=335, tbht rb=349.7, tbht ps=341. With this the anode current is 24.42 at anode voltage=250V. *THIS WILL BE THE MAXIMUM VALUE"

Wednesday, July 11, 2018, 17:15 Mass Scan measurement seem to not vary with anode voltage

Wednesday, July 11, 2018, 17:45 Coil to 60 A to let out gass a bit more overnight. Vacuum ok at 9.6e-7

Thursday, July 12, 2018, 07:25: Power outage. (07/11/2018 @ 21:53 approx) The test stand was completely knocked out. Power & pumps were all shut down.
