Configuration for Production Runs
Production data is taken with the following configuration, which has to be selected at the RCM Run Config GUI:
RUN: | EXPERT |
SETUP: | hd_all.tsg |
CONFIG: | FCAL_BCAL_PS_m9.conf (main production mode) or |
FCAL_BCAL_PS_m10.conf (debug mode, readout raw samples for FADCs 250 and 125) |
Trigger Types
1. GTP Triggers
Currently, there are following main (GTP) triggers used in 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 listed in
2. TS Front Pannel Triggers
Several ancllary triggers, which are used to monitr/study detector performance run in parallel to the main production triggers. These 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. |
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 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 |
