The main installation and trigger activities can be organized into the three main phases:
- 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 a muster-TI 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 the master-TI for small sub-systems (like the microscope, SC, PS)
- Final Detector installation
- Detector Calibration with the Beam
Phase I
BCAL
Can run up to 6 crates with 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 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
| Detector | Trigger Types | Descriptions | Start Date |
