Topics for discussion

1. Overview main features of the GlueX subdetectors which are planned be integrated into the Level-1 trigger:
   • Tagger microscope counters
   • Start Counter
   • FCAL
   • BCAL
   • TOF

   Discuss:

   1. feasibility of usage and their role in the Level-1 algorithm,
   2. rates induced by electromagnetic and hadronic interactions,
   3. signal responses: pulse shapes and signal propagation timing

      (feedback is needed from the prototypes test: BCAL, TOF)

   4. signal thresholds,
   5. cabling.

1. Overview the trigger algorithm.

1. 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:
  1. F1ADC (modes, FPGA resources...)
  2. Signal Distribution (SD)
  3. Trigger Interface (TI)
  4. Crate Trigger Processor (CTP)
  5. Results from the 2 crates test stand

• Specifications (design) of the board prototypes:
  1. Sub-System processor (SSP)
  2. Trigger Distribution (TD)
  3. Trigger Supervisor (TS)
  4. Global Trigger Processor (GTP)

5. Monitoring of the hardware performance

  - Online monitors ( scalers )
  - algorithm/hardware test using inputs from MC simulation
