Two thermocouples were inserted through the left side of the copper heat shield, see attachment #1. One thermocouple is attached to the target
tube with a Ta-wire, and the other is attached to the back block. |

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. |
