Front Panel Trigger Summary Table
The 4 Front Panel triggers listed here were included in the production configuration for the full Spring 2018 Run Period.
| 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 |
|---|---|---|
| CDC time window delay | 41482 | Move hits closer to the beginning of the time window to reduce "shadowing" of signal hits |
| CDC readout changed to mode 3 | 41502 | Switch to reading out pulse integral and peak (readout mode 3) for the CDC. Before this only the high resolution peak was in the readout. |
