Thursday, March 01, 2012, 14:35
Both the IEVAP2:TBHT and IEVAP2:TGHT maximum current setpoints on the vacuum page (see page: /edl/ievap2_vacuum1.edl) are wrong.
For IEVAP2:TGHT, the maximum current setpoint should be 1500A (see page: /edl/ievap2tghtcp.edl), not 1000A. |

The Evaporator #2 backing pump (IEVAP2:BP1) muffler has not connected to the exhaust duct.
See attachment#1 as to where the muffler should be connected to the exhaust ducting system. |

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. |

The tube heater power supply current readback and setpoint are not matching. Ray Dube checked the power supply and confirmed that it is faulty.
He will replace a functional p/s tomorrow. |

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 |
