| Quote: | Small turbo #2 is the forepump of the maglev.
It failed last night, shut down the maglev and interlock closed V1
Ifo pressure is 20 mTorr now. The Yarm was still locked at 8am this morning.
The PSL beam to MC was blocked just before the output periscope.
The psl mechanial shutter did not work from epic screen. |
The PSL mechanical shutter actually did trip last night, greatly confusing me and Rana. Not realizing that the software vacuum interlock had tripped, we manually re-opened the shutter. I'll modify the relevant MEDM screens to indicate when the EPICS interlock trips. |
