- Measured QE ~ 3.5% with -100 V Gun bias. Was about 0.4% with -1 kV bias. This is to be compared to QE ~ 3.9% in Prep Chamber with -280 V bias before moving the photocathode to Gun.
- Gun vacuum improved when opening the gate valve to beamline
- Beam to F-Cup
- Plan to complete the second part of beamline in two weeks. We will have one-week down in about 2 weeks to install the second DP can, solenoid, ion precipitator and the BNNT diagnostic station.
