FP Input | FP Bit |

FCAL LED | 3 |
BCAL LED Upstream | 9 |
BCAL LED Downstream | 10 |
Random pulser | 12 |
Monitoring Configuration File Changes
The configuration files (e.g. FCAL_BCAL_PS_m9.conf) are stored in RCDB for each run, and contain all the relevant configuration variables. This link: Configuration File Changes: Spring 2018 provides a list of when the standard production configuration file changed (according to RCDB), and the difference with the previous configuration file. The specific run numbers for various trigger changes in the table above are derived from these configuration files.
Summary of Configuration Changes
Parameter Changed | Run Start | Comment |
---|---|---|
DSC2_COM | 40941 | TAGM discriminator threshold modified |
FADC250_W_WIDTH and FADC250_READ_THR | 41041 | TPOL readout window widened and threshold raised |
FADC250_USER_VER | 41066 | Modification to FCAL ring masking in L1 trigger |
TRIG_TYPE | 41090 | Remove FCAL-BCAL-ST trigger to the standard trigger mix |
FADC250_W_WIDTH and FADC250_READ_THR | 41099 | TPOL readout window lowered and threshold lowered (revert change in 41041) |
TRIG_TYPE | 41102 | Add FCAL-BCAL-ST trigger to the standard trigger mix |
FADC125_COM_VER | 41202 | Update CDC thresholds (Naomi) |
FADC125_W_OFFSET | 41482 | Move hits 160 ns closer to the beginning of the time window to reduce "shadowing" of signal hits |
FADC125_W_WIDTH | 41507 | Shorten CDC readout window 200 -> 174 samples (208 ns shorter). |
FADC125_MODE | 41508 | Switch to reading out CDC pulse integral and peak (mode 3) for the CDC. Before this only the high resolution peak was in the readout (mode 5). |
