Ciao a tutti,
During Runs 20169,20170,20171 we had 8 boxes death on PRASE (6B01..6B08).
The problem was related to a PHRASE MIXER module (MIXER CAEN 16 CH MOD. C291).
In order to power cycle this crate (PHRASE SM6 CRATE B) I stopped RUN 20171,
then during run 20172 I checked the rates for these boxes with the histogram
presenter.
Ciao, Roberto.
