2, 5 and 8 had 100 ms Quenches back in Sept.  That is an indication of a 
multipactor.   They should be pulsed processed.

I don't know why cavity 1 is turned down so low.

I will check recent data for electronic quenches in 1L05 1 and 8 and 100 
ms quenches everywhere else in 1L05 later this afternoon.

If you are processing 1 or 8 and the adjacent vacuum valve closes due to 
an outburst you should stop doing that cavity so that you lower the risk 
of the valve shedding particles.
