|
TCS:MP1 was tripping of intermittently yesterday. It was found by Dave Morris that the current sensor was not set correctly causing the pump on status
to flicker at times. Dave adjusted the settings yesterday. The system should be operational and is currently running normally. |

|
Chad and Anders inspected the test target in the hot cell today. The lid had been previously removed.
The EE looked to have performed well.
A piece of Ta foil was found inside the heat shield. It is not clear if this
has been there during operation or if it entered the heat shield while in the hot cell. The foil has markings which indicate that it has seen heat.

The target was inspected by Chad and Anders. Photos are available on DocuShare.
It was noticed that the target tube heater terminals had lifted up from the insulator on the target assembly as seen in this Photo.
This has later been detemined to be from the assembly, where additional clearance was required and achieved by installing |

Today 57 kV reached, but observed sparking on the resistors of the new HV cable. The cable will be removed to take out the resistors, before reinstalling
it. |

|
Chad and Anders inspected the Source Tray today using the camera in the hot cell. A dark spot was observed on one of the four insulators separating the
Extraction Electrode from the Ground Electrode. This could potentially influence the high leakage current. Some discolored areas were also observed in
the Service Tray, but these was present when the module was built. See attachment for details. |
