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 start tuning trigger parameters
- 4 TI boards were populated with 4 additional transceivers and can be used as master-TIs handling the clock and trigger distribution for up to 6 crates
- One extra transceiver was added to 4 TI boards. They can be used as a master-TI for small sub-systems (like the microscope, SC, PS)
- 2. Final Detector installation
- Use the global trigger distribution (the global trigger and the trigger distribution crates)
- Up to 4 sub-systems can run in parallel sharing the TS (TS partitioning).
- Calibrate DAQ (readout windows, pedestals, thresholds, etc.) and trigger parameters (offsets, threshold, etc.)
- 3. Detector Calibration with the Beam
Phase I (Initial Installation)
BCAL
Can run up to 6 crates with the master TI
- Pulser for pedestals calibration
- Can be generated by the master TI
- 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.
- LED 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
FCAL
Can run up to 6 crates with the master TI
- Pulser for pedestals calibration
- Cosmics
- Energy summed in the crates (CTP). Energy threshold set at SSP.
- The trigger is sent from the SSP front pannel to the master TI.
- LED Pulser
- The same as for the BCAL
CDC
Can run up to 6 crates with the master TI
- External trigger from paddle scintillators
- Use as input to the master TI
FDC
Can run up to 6 crates with the master TI
- External trigger from the paddle scintillators
- Use as input to the master TI
TOF
One master TI to read out two crates
- Pulser for pedestal calibration
- Cosmics (?)
SC
- Pulser for pedestal calibration
- Cosmics
- Hit bit pattern trigger on the CTP
- Algorithm is being implemented.
