Objectives:
- Test drive the AIEC software
- Demonstrate that the CDC gain is stable
Strategy:
- Designate 2130V as the nominal HV for cosmics, to raise more hits above the noise, but keep 20V headroom for the AI.
- Tell the AI that the HVB current is constant at 9uA so that it can operate within the range of its trained data
- Use 1V steps and 1h runs
Needs:
- AIEC software to read epics and wait for a stable period before calculating the gain and setting the HV
- Method for scaling the HVB current to what it would be at the nominal HV before running the AI - will not be needed for cosmics but will be needed for CPP.
- Script to project dE/dx for 4-10 GeV tracks, fit it and calculate the gain factor
Questions:
- Do we need to force a B field in the reconstruction sw (wait for Simon to answer)
- Simon reported progress on straight track reconstruction
- Full DAQ or standalone DAQ?
- Ask Sergey for configuration with only CDC, BCAL, start counter, FDC.
- When are we doing this?
- Need to coordinate with Hall-D. Potentially Feb. 24 - Mar. 10?
