Configuration for Production Runs
Production data is taken with the following configuration. The configuration has to be selected on the RCM Run Config GUI when you start DAQ using rcm.sh (see descriptions at the DAQ page). Make sure that the following config parameters are set:
RUN: | EXPERT |
SETUP: | hd_all.tsg |
CONFIG: | FCAL_BCAL_PS_m9.conf (main production mode, used for the data production) or |
FCAL_BCAL_PS_m10.conf (debug mode, readout raw samples for FADCs 250 and 125) |
Trigger Types
1. GTP Triggers
Currently, the following main Global Trigger Processor (GTP) triggers are used for data production:
Trigger Type | Trigger Bit (starting from 1) |
---|---|
FCAL + 0.5 BCAL > 0.5 GeV | 1 |
BCAL > 1.1 GeV | 3 |
PS | 4 |
Trigger bits used in spring 2016 are can be found here.
2. TS Front Pannel Triggers
Several ancillary triggers run in parallel to the main production triggers. These triggers are distributed through the TS front pannel, and are used to monitor/study detector performance. The triggers are listed below:
FCAL LED | The pulser can be enabled using the FCAL css screen. FCAL team can also run an LED pulser script, which is currently not controlled through the css. |
BCAL LED | The pulser can be enabled using BCAL css screen. Usually the pulser script is enabled, which alternate upstream and downstream LEDs for various BCAL collumns. |
Random | The random trigger can be enabled from the PS css screen. |
Assignment of the TS FP trigger bits and typical trigger rates are shown in the table:
Trigger Type | Trigger Bit (starting from 1) | Typical rate |
---|---|---|
FCAL LED | 3 | > 10 Hz |
BCAL LED | 9, 10 (single or both bits can be seen, depending on the bcal LED script) | > 1 Hz |
Random | 12 | 50 Hz |
Note, all these FP trigger bits are enabled at the TS by default. If you don't see them in data or online using the trig_client monitor, check whether pulsers are enabled in the FCAL/BCAL/PS css screens (contact with the FCAL/BCAL detector representatives).
Trigger Monitor
Trigger rates produced by the detector (generated by the GTP) and also distributed from the TS front pannel can be monitored using trig_client program. To run the program:
- Login to the gluon machine under hdops and execute trig_client.
- If trig_client is already running, you will get the message on the xterm screen.
- To restart the client, kill the process and delete the logfile
- /home/hdops/CDAQ/config/hd_server/trig_client.log
An example of the trigger monitor screen, is shown below
