keyword=T8 the culprit of all problems
We think T8 caused all problems. The prescale factor ps8 was 100
(we see this in event type 120, the readback of TS), but most of
the events are T8, as if there was some massive multiple pulsing
on this signal.
We saw it in the hall too, did a run with large rate. Brad unplugged
T8 and the deadtime became normal. Then plugged in T8 again and
it is now normal. As if a flakey cable but we don't see it. Plan
to run like this and if it recurs, unplug T8 at TS.
