GTS meeting 11 06 17

• Beamline bake

• New bialkali antimonide photocathode was activated (full area) with QE ~4.8%.

• Gain switched diode laser at 1064 nm will be ready for installation next week (1064 nm, 50-70 ps Gaussian pulses, efficiency > 30%, 500 mW output, 400 MHz).

• Planned measurements:

1. Measure beam magnetization (beam sizes and rotation angle) versus solenoid field from photocathode center and for two laser sizes
2. Map beam emittance vs spot location
3. Measure lifetime at 5 mA with RF laser and solenoid magnet off/on
