     Ciao a tutti,

     checking the WFD data, I found that this tank had high Ndata during
     last runs (max. more than 11000 in run 19278, 5-6000 in the others).
     Using the scope, the signal looks very bright, unstable and it seems
     to have a double gain (with one of the gain at 2-3V).
     We decided to turn off this PMT starting from run 19290.

     A presto,

                                Nicola
