Target oven is coated with TaC. The oven is wrapped with 3 Ta-heat shields.
The chamber is currently being pumped down. Vac @ high 10e-5 Torr. Heater will be turned on once the pressure is gone down to low 10e-6. |

A new target boat was sprayed with TaC coating and let dry, the coating appeared slightly bubbly once dried [see attached photos].
The target boat was wrapped with 3-layers of Ta-heat shield. |

After upgrading IOC for CXML program, experienced some issues; therefore, switched to same software as EVAP2.

According to Jonathan Aoki, the electricians will be servicing another MCC which will result in loss of cooling water for about 8 hours starting at 16:00
March 30. We shouldn't be running the evaporator or any condensers at that time. |

| It's the NON-ACTIVE water that will go off. The evaporator is on sity water, so it will be OK. |

|
The evaporator ion gauge filament burnt out on May 11, 2011. A target was in the evaporator at that time and was about to being the sintering process.
The gauge had two filaments, so vacuum group helped to switch to the second filament. The evaporator was vented on May 17, 2011, and a new ion gauge
with two filaments was installed. The gauge was tested and it's working fine. |

Due to the differences in the use of the graphite foils in past SiC targets (C-grv foil from Alpha Aesar) and the newly prepared SiC#27 (C-grv
foil from Ceramaterial), the out-gassing period for SiC#27 took over 6 days compared to 3 days for the vacuum to come down (see https://elog.triumf.ca/TIS/Evaporator_1/47). |
