Timing and spills¶
Running the Spill Server¶
On a DAQ machine, set up the software:
setup_online -z 1 --opt
and then run the script to start the spill server:
./home/novadaq/testRel_TBOps_20180821/DAQOperationsTools/script/startBeamSpillBackBoneTB.sh
(this is for a specific Ops release).
This starts the NssApp on the TDU and the Spill Forwarder on the test-trigger machine.
Logs are placed in
/daqlogs/NovaSpillServer/NssTDUApp/
TDU Spill numbering¶
The various spill types the TDUs see are listed below.
1: BNB (evt 0x41b) - Beamline trigger 4: AccelOneHztclk (evt 0x18f) 7: SuperCycle (evt 0x100) 10: TBSpill (evt 0x139) - Full 4.2s spill
IRM Outputs¶
The TCLK outputs for each of our IRM channels (2-26-2019) are as follows:- 0: $00 (RESET)
- 1: $8F (1Hz)
- 2: $30 (switchyard reset for long spill extraction)
- 3: $36 (switchyard post-beam)
- 4: $31 (switchyard reset for extracted beam)
- 5: Software triggered
- 6: $00+delay (END READOUT)
- 7: $00+delay (END READOUT)
