- Beamline bake is completed
- New bialkali antimonide photocathode was activated (full area) with QE ~4.8%
- Gain switched diode laser at 1064 nm is ready for installation this week (1064 nm, 50 ps Gaussian pulses, efficiency > 30%, 1.5W output, 1497/8=187.125 MHz)
- Planned measurements:
- Commission harps
- Map beam emittance vs spot location and laser size
- Measure beam magnetization (beam sizes and rotation angle) versus solenoid field from photocathode center and for two laser sizes
- Measure lifetime at 5 mA with RF laser and solenoid magnet off/on
