- General/CREX analysis
- Beam through the chicane. Looked good.
- There were laser-on drifts due to beam motion in the chicane.
- Ops want us to use the Moller lock during production. This would require changing the lock. We're happy with any solution that locks to the Compton table BPMs.
- Some snail have very good data: good separation, small error, good chi2. Some have double peaking in the pedestal.
- Use snapshot pedestal to correct accumulators? Code doesn't exist, would need to be developed.
- TODO Make plot of pedestal as function of time from snapshots.
- Discussion about reading out tube voltage and current or DAQ temperature.
- Electron detector
- Adaptor boards have not been tested yet so the reaming boards haven't been populated with resistors. It will take about 1-2 weeks to stuff the boards and another 2 weeks to ship them once the correct resistor has been verified.
