Checklist maintenance
Hall D is using the accelerator-developed system of checklists, commonly referred to as the hot checkout (HCO). The system is driven by a web-based interface with many features that can be discovered interactively. However, there are a few infrequent actions that require specific instructions. Note that some of these require special permissions, not generally granted.
Routine operation
Instructions for shift personnel are available in the Barrel Calorimeter instructions for shift personnel.
Saving and Comparing Save/Restore Files
Specific voltage settings can be saved (from electronics to file) or restored (from file to electronics). This is done via the "Save/Restore" button on the top right of the GUI. The files are automatically saved with the date/time to /gluex/data/burt/voltages/BCAL_BIAS/. We have renamed the files incorporating the date/time temperature and 10 times the overvoltage (to avoid an additional "." in the name). A soft link is created in that directory to point to the nominal file for the current run. The voltages from different files can be compared using the script compare_snap_voltages.C which is located in /gluex/Subsystems/BCAL/scripts.
Chiller Operation
The chiller temperature should be set to 2 degC less than the desired SiPM temperature. The chillers are normally in 'remote' mode. (You can still change the temperature manually). To change the 'set' temperature, use the up/down arrows on the front key pad to the desired temperature. The values are in deg F. Wait for the 'readback' temperature to settle to the 'set' value, as it may overshoot at first. At startup it may be necessary to pull the reset (green) switch forward that is accessed through the hole on the side of the chiller closest to the front.
Expert personnel
The individuals responsible from Hall D for checking that the checklists are prepared to be filled for a given run period are shown in following table. Additional experts on the software itself from accelerator are listed in case issues come up with their implementation.
