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. |

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. |

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. |

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. |

Rick mentioned to me that the evaporator is ready for the next steps of the commissioning process.
In the chamber only the target leg heaters have current by-pass clamps on them.
The ionizer tube heaters do not have them because these lines do not have the same configuration as the others. The current by-pass clamps will
