Announcements
- Yi will be leaving at the end of January. Hall D group needs to learn the slow controls subsystem that Yi has developed. Dave and Brian are looking into the PXI system for the solenoid.
Gas system
- Dave will be working on the gas system controls. Namely he will implement the communications between PLC and the Brooks controllers to be able to set the most parameters in the controller downstairs from PLC. We would like to be able to change the flow or to completely shut off the valves in the MFC in the hall from the hall.
- Dave also suggested to have a NC solenoid valve for each FDC package so that we do not need to rely on the serial controls. It was pointed out that this is something that may trigger a review, the FDC group needs to make decisions on that.
Remote reset of CAENs
- Dave have plans for redoing the remote reset for CAENs without using 5V output modules that currently kill the HV from CAEN each time PLC is rebooted.
- May require additional purchases of PLC equipment, Hovanes will ask Eugene about POA.
Warm magnet power supplies
- The procedures for TAG5C and SWEEP magnet ramping require approching the desired setpoint from above after staying near the saturation point for a while.
- During the fall run we had incidents for both PS and tagger where the magnet currents were not raised to the maximum values before putting them at the nominal setpoint.
- Accelerator magnet approach the desired setpoints from below, so the existing software does not accommodate TAG5C and SWEEP, but probably can be modified to execute our simple loop.
- Hovanes will talk to Gary about making such changes.
