== 1. Overview main features of the GlueX subdetectors
which are planned be integrated to the Level-1 trigger: ==
- Tagger microscope counters - Start Counter - FCAL - BCAL - TOF
Discuss:
- feasibility of usage, their role in the Level-1 algorithm, - rates induced by electromagnetic and hadronic interactions, - signal responses: pulse shapes and signal propagation timing (feedback is needed from the prototypes test: BCAL, TOF) - signal thresholds, - cabling.
2. Overview the trigger algorithm.
3. Trigger types.
- global self-triggered types (physics, cosmics, random, calibration ...), external triggers (calibration), and sub-detector standalone triggers
Feedback is needed from sub-detector and calibration groups.
4. Overview trigger electronics:
Performance of board prototypes:
- F1ADC (modes, FPGA resources...) - Signal Distribution (SD) - Trigger Interface (TI) - Crate Trigger Processor (CTP) - Results from the 2 crates test stand
Specifications (design) of the board prototypes:
- Sub-System processor (SSP) - Trigger Distribution (TD) - Trigger Supervisor (TS) - Global Trigger Processor (GTP)
5. Monitoring of the hardware performance
- Online monitors ( scalers ) - algorithm/hardware test using inputs from MC simulation
