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