Below are some general steps describing the trigger commissioning with the photon beam.
Phase 1: Photon-beam Commissioning
- PS stand alone trigger (2 - 3 days)
(done)
- - trigger with PSC
- - read out PS and PSC
- - trigger distribution through GTP. Use PSC self trigger if problems with GTP
Phase 2: Photon Beam in the Hall
- Tune FCAL trigger (2 - 3 days) (done)
- - trigger based on the global energy sum
- - read out FCAL only, raw mode for fadc250
- - adjust trigger parameters, tune timing
- - study rates for various trigger thresholds
- Add CDC, FDC, BCAL, ST, TOF (TAGM/TAGH) to the read out (4 - 5 days)
- - tune timing, adjust trigger prescalings
- Take some data for detector calibration
- - production runs during nights if the system is robust
- - run with high-energy thresholds
- - low-energy thresholds for CDC/FDC calibration
- Tune BCAL trigger (2 - 3 days)
- - trigger based on the global energy sum
- - alternate FCAL production runs with the BCAL trigger tuning
- Production runs with BCAL (FCAL & BCAL) triggers
- Tune TOF/ST triggers (4 - 5 days)
- Take additional calibration data for CDC/FDC
- Integrate & tune TAGM/TAGH to the trigger (low priority) (4 - 5 days)
- - note, TAGM/TAGH could be read out using other trigger types
- - take data with TAGM/TAGH and the PS for the tagging efficiency study and calibration
Note, commissioning may require significantly more time depending
on the system performance.
