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