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.
Downgrading status
This can all be done on the signoff page. For any given system there can be multiple responsible groups so you'll need to decide if all groups will have their signoff downgraded or just a subset. The group signoffs in a particular subsystem are ordered left to right so choose the group at which downgrades should begin and all groups to their right will be cascaded down. For Hall D, select the "mechanical group,"which is usually the first one (left-most) and all other groups will be downgraded also. After selecting the group/subsystem combination, use the 'Downgrade options' on the bottom right to select the downgrade action requested for a given status.
Tips: Use the blue arrow button on the top of the signoff table to select an entire column of signoffs. You may find using the "Start with Category" checkbox found in the top right corner of the signoff screen makes navigating the component tree easier for the downgrading task, especially if you decide "Checked" is not downgraded far enough and you need to change your group selection without losing your subsystem selection.
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.
