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. |

|
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. |
