GTS meeting 3 21 17

• With both solenoids at +2.0 Amps, the solenoid field direction is pointing downstream along the beam path. The field of the magnetized gun solenoid is pointing out of the photocathode into the downstream direction.

• 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 next week (March 27, 2017):

1. Monday, Tuesday and Wednesday: open in morning to install 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 250C hot gas through the water lines of the FCup to degas.
