keyword=BB deadtime fluctuationsWatching datamon, the deadtime is normally 3% at 10 uA, but I
see some huge excursions (fig 1). The time I captured this
corresponded to the time marked "deadtime" in fig 2.
The top plot shows beam current and the bottom plot shows
the accepted rate (L1A). If L1A drops while beam is stable
it is due to deadtime.
This is related to the other halogs on this topic.
