The ETMX oplev returning beam is well centered on the qpd. We lost this signal 2 days ago. I will check on the qpd.
ETMX sus damping restored

As reported a couple days ago, the ETMX IO chassis has no timing signal. This is why we there is no QPD signal and why we turned off the ETMX watchdog. In fact, I believe that there is probably nothing coming out of the ETMX suspension controller at all.
I'm working on getting the timing board replaced. Hopefully today. |
