       Hi all,

             during run 19710 (lasted ~4hrs), 4B10-1 started giving
             a high TOHM trigger rate. Looking at the signal with the
             scope, it was flasher. I turned it off at the end of run
             19711 that was stopped by italian technicians in order
             to replace a broken QTP module.
             The replacement of this PMT will take place within tomorrow.
             

                                   Nicola
