keyword=DVCSMux configurationIt seems that DVCSMux configuration has some problems when running at this kinematics. TDCs of blocks closest to the beam are very noisy. We still see the coincidence peak, but a high pile-up is present at the end of the ARS window. It would seem that the trigger window is larger than before and we get too much noise.
Dead time for this configuration was 9.2% and counting rates 50Hz (to be compared with 15% and 25Hz respectively for the regular DVCS configuration).
Before fixing the problem with this configuration and given the fact that the dead time reduction is not that big, we will keep running with the regular DVCS configuration tonight.
