The LP-SIS RFQ target container was previously coated with TaC and sintered up to ~1500C (TGHT @ 600A, TBHT @ 300A).
The container is loaded with 325 discs of SiC, a total of 10.9cm in length. |

This is to test the newly developed RFQ target to be commissioned this year. The purpose of this test is to see how well the RFQ components
can sustain the high temperature. One thermocouple is connected inside the target and the other is connect outside of the Cu heat-shield. RGA |

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 |
