  • 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:
  1. Commission harps
  2. Map beam emittance vs spot location and laser size
  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
