COMMENT ON Investigate IPM5C11A Heater
No further regulation issues have been noted. However, it was found that there are some comm issues. It was decided while hall D reconfigures to use their installations including IPM5C11A to try and iron out the lack of alarm propagation. We will be powering the units off and on and potentially disconnecting their comm cables. As such some alarms are to be expected. Prior to any changes Mcc will be notified and coordinated with.
North Linac Level faults, 1L18 and 1L20
The superconducting level measurements for 1L18 and 1L20 froze and stopped reading correctly.
1L18 froze at 1449 on 4-23
1L20 froze at 0736 on 4-25
Power cycling the AMI-1700 level monitor units restored functionality. 1L18 had in fact emptied to 33%, while 1L20 had overfilled to ~96%.
Our investigation into this continues.
