|
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. |
