- Remaining tasks before shutdown:
- Slit-Viewer emittance measurement: Slit1 and Viewer3 with focus lens
- Measure lifetime with a larger laser size (~rms=0.5 mm)
- Measure lifetime for: 0 A, 50 A, 100 A, 150 A, 200 A, 300 A, 400 A (Gun HV=300 kV, I=3.0 mA) - Done - [1]
- Lifetime vs biased anode
- Why is photocathode lifetime limited (100 - 300 C)?
- Laser heating and QE decay
- Laser size too small?
