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 |

The HP-SIS SiC target was made on Nov 03, 2010. The target consists of 405 discs, 18.5cm in length. It was sintered in the Evaporator#1.
This target is going into Evap#2 for re-conditioning. It is currently being pumped down. |
