Occupancy T0 Counters

•The occupancy of the T0 counters, especially T0N, depends very much on the trigger conditions.

•Expectations based on UA5 data:

•

•T0N: <N> = 0.56 (P(N=0) = 57%)

•

•T0P: <N> = 0.41 (P(N=0) = 66%)

•

•The data show that the occupancy for T0P is higher than the occupancy of T0N. Is this due to a much higher background in T0P?
