Objectives:
- Test drive the AIEC software
- Demonstrate that the CDC gain is stable
Schedule:
- 2022-02-25 Fri. - Test fully automated CDC HV control
- 2022-03-01 Tue. - Start system
- 2022-03-07 Tue. - Change configuration (left/right -> top/bottom)
- 2022-03-14 Mon. - End test
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
- Starting new run every hour for 2 weeks may not be feasible. Devise scheme to break up long runs?
Needs:
- AIEC software to read epics and wait for a stable period before calculating the gain and setting the HV
- What determines "stable"?
- Who?
- 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.
- Is this something that could be tested during cosmics run? (yes=implement, no=defer)
- Script to project dE/dx for 4-10 GeV tracks, fit it and calculate the gain factor
- Is this for needed for cosmics? (monitoring?)
Code to set whole quadrants to same value(cdc_tool.py)
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 (email to David and Naomi Feb. 24th)
Full DAQ or standalone DAQ?- Ask Sergey for configuration with only CDC, BCAL
When are we doing this?- March 1-14, 2022
