Two minor chips in the main 60 kV insulators on the source tray was inspected today by Anders, Tom and Aurelia. The chips are small enough that
they should not be a problem. See photos for details. |

|
On maintenance day Tuesday, the roughing of the target station could not go below 1.5 Torr. A brief troubleshooting on Tuesday was unsuccessful in determining
the cause. Leak checking continued on Wednesday by David and Anders. A leak was finally found on the multi pin connector feedthrough due to the seal between
the connector and flange on top of the nylon insulator. Upon re-tightening the connector, the leak could be stopped and the module pumped down to allow |

|
The Source tray was inspected in the RH shop today by Anders, Friedhelm and Jens. The routing of the lines are satisfactory, however a design proposal
to remove the ground electrode line will be made. This design will have to ensure a proper connection from the electrode to ground (using the window cooling
lines). All other lines are OK at this point. Some fine adjustments are expected after brazing and soldering to maintain high voltage separation. Photos |
