keyword=He3 elastic countsThis is from 200.000 events of run #3112.
We are getting about 500 elastic counts (see magnified image)
in this chunk of data, i.e. about 10.000 elastic per full run
which has 4.0M events and takes 1/2 hr at 10uA beam current.
So we intend to stay here for about 5 hours to accumulate
100.000 elastic counts or 0.3% error on the asymmetry
(which is approx 3%).
