The main installation and trigger activities can be organized into the three main phases:

  1. Initial installation phase, where only a few crates with electronics are installed and connected to the sub-detector.
  • Run stand alone DAC for each sub-detector. Start calibration of fadc pedestals, implementing calibration triggers and tuning trigger parameters
  1. Final Detector installation
  2. Detector Calibration with the Beam


BCAL

  • Cosmics
Generated by CTP in each crate. Possibility to generate the trigger for each BCAL module.
ID of the 'fired' module is sent to the SSP along with the energy sum.
The trigger is sent from the SSP front pannel to the master TI.
Algorithm is being implemented into the CTP.
  • Pulser
Initiated by 2 CAEN 1495 board (24 TTL outputs)
LED pattern programmed through EPICS
LVDS output is used as an external trigger for the master TI
