Trigger Commissioning

Trigger Commissioning Plan

Phase 1: Photon-beam Commissioning

• PS stand alone trigger (2 - 3 days)

- trigger with PSC

- read out PS and PSC

- trigger distribution through GTP. Use PCS self trigger if problems with GTP

Phase 2: Photon Beam in the Hall

• Tune FCAL trigger (2 - 3 days)

- trigger using global energy

- 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) (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
