GTS meeting 3 28 17

• Conditioned Gun at 300 kV with solenoid at 0 to 300 A, left to do it at: 325, 350, 375, and 400 A. Two currents, 350 and 400 A, we attempted before but we will repeat.

• Plan for this week (March 27, 2017):

1. Monday, Tuesday and Wednesday: open in morning to install second part of beamline but close in afternoon to run beam
2. Thursday and Friday open all day for beamline bake. Turn ON the extractor gauge in Gun HV Chamber. Use GN2 heater to send 250 C hot gas through the water lines of the FCup to degas.
3. Week of April 3rd: finish bake and instrument beamline

• What we are working on now:

1. Put a laser Newport powermeter at the exit window side of the gun using a RS232 for controls
2. Put cover around laser tables
3. Still trying to center the gun solenoid
4. Do we want to keep the anode biased at +280 V all times (and while running beam)?

• Emittance vs Gun HV: media:Emittance_GunHV_3468399.xlsx [1]

• These are the simulation tasks that we should try:

1. Simulate emittance vs Gun HV
2. Simulate beam rotation at: B=0 G (0 A), B=170 G (50 A), B=340 G (100 A), B=510 G (150 A), B=680 G (200 A), B=850 G (250 A), B=1020 G (300 A), B=1190 G (350 A), B=1360 G (400 A)
