Agenda
Laser
- Cavity noise characteristics study
JLab VtoF and scaler appears to broaden the cavity power width significantly (comparing with fADC measurement of the same signal.)
If this latest width holds out then the new cavity width will be a negligible contribution to the photon detector width.
Photon Detector
- LED linearity system
- Detector
- Cooling system update
Electron Detector
- Source tests

DAQ
- BPM/V2F issue
Attendance
On site: Mark, Don, Wouter, Amrendra, Arthur, Vardan Off site: Jeff, Kent
Minutes
Laser
- After much discussion
Photon Detector
- Have data with snapshots over the LED pulse. Data taken with varying LED intensity and the phototube so first linearity data now available.
- Detector cooling results looking good at 14 degrees C. Actual data to follow.
