We were taking runs for efficiency measurements with TOF R4-R7.
Two runs are completed : 2370 - about 30 k
2371 - about 50 k
The results are in the book.
We noted that TOF7 events go mainly into CC2 instead of CC1, as regular
TOF_EFF.C script requires.
Including CC2 into the script increases the number of events in TOF7 by at least
factor of 4-5.
Also, noted that regular script has good time limits for pads, but very loosy ones
for start counter (1-4000). That lives in some fraction of accidentals. Including
strict cuts for start counter time improves efficiency by about 2 %.
Measured efficiency is 93-95 % for TOF 4-6, and about 87-88% for TOF7.
The ADC spectra indicate that, most likely, this is NOT real inefficiency, but
rather geometrical and random coincidences factors (ADC peaks look far above the
threshold).
