| − | The main installation and trigger activities can be organized into the three main phases:
| + | [[Trigger Installation Activities | Trigger Installation Activities]] |
| | | | |
| − | : '''1. Initial installation phase, where only a few crates with electronics are installed and connected to the sub-detector.''' | + | [https://halldweb1.jlab.org/level-1/algorithm/trigger_types.pdf Trigger Types (draft)] |
| − | :* 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, ...) and trigger parameters (offsets, threshold, etc)
| + | |
| − | : '''3. Detector Calibration with the Beam'''

| + | |
| − | | + | |
| − | 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
