It was discovered that one of the insulators that supported the target module broke apart (see Attachment#1). This might be caused by the
heat from the target legs that reflected back from the base to the insulators. The burnt marks are the evidence. |

|
Tuesday, August 14, 2012, 15:01
The Cu-heatshield insulators are broken due to prolong heating time during the target processes (see attachment#1).
The insulators are replaced with the MM800 type (see attachment #2). |

The insulator that holds the terminals was broken when a target container was installed. The insulator had seen so much heat shine from the
Cu heat-shield gaps, see attachment. Tightening the bolts on the target container might further put more force on the insulator and eventually broke |

Rick replaced the backing pump hose from 1.5" to 2.0" for better flow. And the HEPA filter was checked - it looks OK.

It was found that after the last process, Evap#2 has broken insulators - the cylinder insulator that supports the target centre legs and the block
insulator that supports the terminals. |
