It was discovered this morning that the Evaporator #2 chiller was leaking water from the bottom (see attachment 1). A puddle of water was
formed and eventually found its way down to the Hotcell. |

The evaporator was used for the processing the NiO target for 8 days and it was discovered today that there was a puddle of water underneath the
chiller. |

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 |

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 source of the poor vacuum in the backing line seems to be related to a dirty filter. We will try to find a replacement filter next week.
The problem seem to have started September 17th, when backing preassure CG1A went from 40 mTorr to 130 mTorr. CG1B remained around 30 mTorr. |
