They are all now properly set and verified proper compression using the Swagelock gage. Please transport the panel out to the gas shed. I think it should be put it inside. The DSG folks will then make some temporary connections to do the flow tests on it. They should pipe the exhaust out of the shed or have the overhead door full open while testing and remove all temporary tubing before closing the overhead door.

Once he receives the gauge, we will check the panel and tighten the necessary connections. After the panel is checked, the panel will be moved over to the Hall B Gas Shed for the full-scale flow test. DSG will need assistance from Hall B Engineering to move the panel as we do not have the transportation equipment necessary. Before the full-scale flow test, George will generate a diagram showing the panel connected to the nitrogen supply line.

This moisture transducer is on RICH and is not part of the RICH pressure transducer. It is separate from the nitrogen panel upgrade. Installation of the moisture transducer would not take long. The plan is to get all parts ready, remove the existing gas line, and quickly install the moisture transducer to limit the chances moisture enters RICH. This sensor will be read by RICH's N2 cRIO and will only be monitored; no interlocks will be on the sensor.
