keyword=scaler BB T2 rates on Sunday and today are about the sameBrad asked me to check out why the deadtime for BB changed before
LHRS polarity change. Is this due to beam quality? The rater pattern seems pretty good for the last run (before Moller started, see previous entry).
I did a quick check of scaler rate:
run 1927 on Sunday, with 10.17 uA, T2=1818.5 Hz.
run 1955 today, with 11.85 uA, T2=2109.9 Hz.
They are the same. No change.
So seems the deadtime probably is not due to beam quality.
