Friday, September 23, 2011, 16:3: The connection on the 9-pin connector for FEBIAD targets showed burn marks from the previous FEBIAD tests. Corresponding
mark was found on the connector on the target side. Because of this the upper and lower 9-pin connectors were swapped to have a clean connector for the
next FEBIAD target. |

|
While testing SiC#26 a leak was discovered on the water line to the heat shield. The leak was in the right joint (see attachment). The heat
shield water lines were removed from the test stand and repaired in the Machine Shop.
Kapton was added to the FEBIAD coil line to prevent
it from shorting to the target heater line (see attachment).

The insulator for the tube heater was observed to be glowing with a blue shine when the target was on high voltage. The insulator was glowing
on the side closest to the 9-pin connector. See attached photo. |

When the target was removed from the test stand it was discovered that the custom designed insulator stand-off (ITD0400 made from Mycroy 1100)
had swollen and become discoloured in the area exposed to "heat shine" from the target oven. See attached pdf for photos of the insulators.
The heat shield lid was opened up and the target temporarily removed to replace the two insulators that had failed. These were replaced with the |

A chip of insulator material was detected below the lower target insulator stand-off (attachment - left picture). The chip may come from the tube
heater insulator above (attachment - right picture). The chip will be further investigated when the target is removed. |

During the mass scan today it was discovered, that the mass calibration was off. Further investigation showed, that the Hall probe readings are a factor
of 1.31 lower than during previous measurements. A fault report has been issued to controls. |
