Hi guys,
yesterday we found out the counter 4B08 seemed to have a double gain peak on
side 0 and for this reason today we turned it off to open it but actually,
after having unplugged the splitter box, we tested both pmt's and we noticed
that the signals were fine.
In fact, when we connected back the splitter box the problem desappeared and the
counter has been turned on after few hours.
A presto,
Massimo.
