Minutes
Present:
- FIU: Werner Boeglin, Mahmoud Kamel
- JLab: Mark Ito (chair), Eric Pooser, Simon Taylor
Collaboration Meeting
FIU will make the presentation. They will need 30 minutes. It will be some combination of Eric and Mahmoud.
We had a brief discussion of ideas for an online calibration. Werner pointed out that the thing we need to know earlier rather than later are the various thresholds of the detector.
Detector Status
Stable. The start counter is in the bore and ready to take data.
Calibration
Work continues on refining time-walk corrections and propagation delay corrections.
- Time Walk. Eric is exploring using the pulse maximum rather than pulse integral as the input to the time-walk correction function.
- Propagation Delay. Using the Fall data to measure the delays has been difficult. FIU will try to use the test bench data obtained during construction as a basis for a correction scheme.
Next Meeting
We agreed to meet again in a week.
