Looking at the pulse height distributions in the Michigan chambers, generally
the median pulse height is at or above what it was last summer with one notable
exception - chamber 112 has a median pulse height of 57, about half of what I
would like to see.
Chambers 105-108 have improved greatly as a result of the higher voltage.
efficiency...
run 1056 run 1071
105 89.1% 96.3%
106 74.6% 92.2%
107 60.8% 94.2%
108 68.0% 93.9%
As has been true in the past, inefficiencies occur in pockets in the chambers
which have overall low efficiency. In order of decreasing severity, I find the
following bad areas:
Chamber wires
124 48-112
123 64-96
115 64-80
101 48-64
... etc.
