Ciao a tutti,
a black-out lasted ~ 35 min (at 9:20 AM) occurred today. Our
batteries went completely down but, fortunately, we shut-down
the detector before. Note that some electrical power interruption
were scheduled (and occurred) for these days but with a max. duration
of 60 sec. (!!!).
After usual procedures and debugging, we restarted the full detector
at 1:50 PM, starting from run 20127. Thanks to God, no corpses
were produced today.
In agreement with the italian shiftworkers and technicians (that need
some additional works on the streamer electronics), we
decided to postpone the maintenance/calibration day to the next
Wednesday (22-Nov-2000).
Let us know if you agree.
A presto,
Nicola
