L1 trigger commissioning plans for the spring 2016 run
- PS trigger
- - PS trigger efficiency studies (using TAGM/TAGH, FCAL & BCAL triggers)
- - Threshold scans
- FCAL & BCAL main production trigger
- - threshold scans for individual FCAL and BCAL triggers (study trigger time dependence on thresholds, rates)
- - collect data samples using the FCAL and BCAL individual triggers
- - introduce individual thresholds for BCAL and FCAL energies for the FCAL & BCAL trigger
- - tune timing offsets between BCAL and FCAL (rate scans)
- - trigger rate studies. Adjust energy thresholds. Take data for different thresholds and different luminosity
- Implement TS FP triggers
- - BCAL LED
- - FCAL LED
- - PS LED
- Implement multiple triggers (initial implementation)
- - combine PS, FCAL & BCAL, FCAL, and BCAL triggers
- (note FCAL and BCAL triggers may be taken out from the production trigger later on).
- - add TS periodic pulser
- - add TS FP triggers
- - combine PS, FCAL & BCAL, FCAL, and BCAL triggers
- TAC trigger
- - implement TAC stand alone trigger
- - implement configuration with the PS and TAC triggers. Read out TAGH/TAGM crates
- Implement triggers for efficiency studies (have to decide what would be the best rigger for this, besides the minimum bias)
- Implement TAGH/TAGM triggers
- - combine TAGH/TAGM with other trigger types
- Trigger for FDC alignment (ST / TOF + FCAL )
- Trigger for FCAL MIPs calibration ( ST & TOF )
- Improve BCAL & FCAL triggers at low FCAL energies (use coincidences between FCAL and ST/TOF)
- PS trigger (TAGM bias voltage calibration, TAGH, PS voltage scans, efficiency studies). Run TRD in parallel, if no problems.
- - test/debug trigger (2 - 3 hours).
- - production (1 - 2 night shifts)
- run conditions depend on the accelerator performance (200 nA electron current, 10^-4 radiator, 10^-3 converter + Be converter, TBD)
- Trigger for FDC alignment (ST/TOF + FCAL)
- Trigger for FCAL MIPs calibration (ST & TOF)
- - test/debug trigger (3 - 4 hours, CDC/FDC switched off)
- - production at low luminosity with the FDC switched on (1 - 2 night shifts for both the FDC alignmnent and FCAL MIP triggers)
- Debug FCAL/BCAL trigger
- - trigger studies (3 - 4 hours)
- - take data with the BCAL/FCAL trigger, FCAL/BCAL thresholds will be tuned, chambers can be switched on depending on run conditions (1 - 2 night shifts).
- - test trigger performance at high rate. Take data with 'nominal' trigger thresholds.
- Trigger generated by TAGM/TAGH
- - trigger studies (3 - 4 hours)
- - combine TAGH/TAGM with other trigger types.
- - take data with the total absorption counter, 2x10-5 radiator, a few nA current (TBD) (2 - 3 hours)
- Special trigger requests from sub-detectors
