Comments
(*) Runs #3602, #3603, #3604 (and corresponding HRS R runs) are
high-deadtime test runs with twice lower beam current (5 uA)
and ps6=1 instead of ps6=2 (and 10 uA) as in run #3600.
(@) Terminated dummy target runs #3608 / #21882 at 0.5M counts
in HRSL which had ~ 300 Hz of T6. Runs #3609 / #21883 with
the LD2 target have roughly the same rate of T6, so keeping
in mind the factor 6 in Aluminum thickness, we should be OK
(S/N of about 10:1) if we get ~ 1.0M events with LD2.
