|
Between feedthroughs F (magnet coil) and B (tube heater negative), I found a jumper with two resistors that has been burned up. I am not sure when this
happened, but it would be good to review the overall setup of the service cap wiring in the new year.
The cable connected to feedthrough Q where the multipin sits also looks burned. |

The system was vented to make clearance on the waterlines as a very small continuous discharge was observed.
The inspection revealed some marks on the HS water line (sideview photo). From the the bottom and from real close (zoom and backview photo) the
marks are quite noticeable with shinny copper in the middle and dark circles around. |

There was a previous DI CU-LCW pump trip as per the above elog. The CU-LCW pump was configured this morning. The water pressure is set to
80 PSI as per the MCR. Any further can overload & trip the pump. |

Determined on Friday April 16th that the water leak was on the coil negative circuit. This was determined by circulating water through once circuit at
the time. Only HF and GE tested (not Extraction Electrode). |

After not being able to get beam through the emittance meter. I diagnosed that the plates was not biased (reason yet unknow).

parameters. |

Problem: Some devices turn off unexpectedly and sometimes without any obvious trigger. In the past, the only time this was an issue
was during mass scans. Now with the automation of measurements, this is a major problem as it prevents longer parameter scans.
Thursday, August 05, 2021, 08:00: Kevin setup the CANBUS snooper by hooking it up on the magnet card loop port. |

Hence, I came on-site to see if there was an issue with the hardware. Nothing obvious.
Last night there were some sparks that might have cause some issue. |
