Spill signal issue after night run
(Posted on behalf of Mengqing)
After a continuous run of aida TLU for one day and one night, using its TLU Spill function all the time, I found the Spill signal had some kind of glitch:
- normally with the TLU Spill configuration I have running at DESY, one will get 0.24kHz of TLU trigger Freq., see the attached screenshot;
- however, I noticed, after a long continuous run, this Freq. becomes much higher (); and even when TLU has not yet 'Start' from EUDAQ, our kpix system immediately starts to collect data as if it gets the TLU Spill.*
- unfortunately, I have not yet tried if KPiX still sees the Emin/TLU Spill even if TLU producer was terminated and not Init.
I figured out how to (may be by chance it was working) revive the TLU once it behaves weird for the Spill signal. It looks like if I changed to Internal trigger and switch off the shutter mode, and start a run, stop it, then reconfigure with normal PMT input and shutter mode, it works then normal. I am not sure if this will help.
