Still no beam... I called for a timetable but CCR is continuing diagnostics with no significant progress at identifying a problem. Without knowing the problem, there is no ability to foretell a time of repair... those are some deep thoughts for you.
Everything seems in order... I took 4 cosmic runs 8723, 25, 26, 27 each with 400k events set on l1trig. An l2trig cosmic is starting now. This is the proper l2trig from the proper settings file, so there is no need to change trigger settings.
Ligit has slowly went up from 1.35-1.5e-7 . If this continues, I told someone to call someone. It took ~6 hours for this rise, so I don't know if this is significant and I've been told many times that ligit fluctuates slightly and exact causes are not completely known. If there was a huge drop or rise, I would have been on the phone immediately.
No broken pipes occurred to test the HV broken pipe script... but a strange thing, and I doubt this is related... On a cosmics run, there was a loss of physics events but no clear message as to a cause. I reinitialized the crates and the right sector TOF crate was not being communicated with. Scalars were gone and still no physics events. The HV also displayed the Right TOF Crate as ON, when all others were off and being reinitialized... This resembles a broken pipe, but could have been a problem communicating with the database... I'm not sure. I rebooted the IOC and everything came back as is.
Have a great weekend
