    keyword=QuasiElastic Detection per Beam Current

    Here are some calculations I did looking at the quasielastic detection for different beam currents. These include 1, 7, 8, and 9uA runs. The cuts are listed below the tables. The first plot includes cuts on the neutron arm. In this one, my guess is we may not be looking at the right clusters or we may be triggering on background putting the real particle out of time, which may explain the decrease.

    Looking at just BigBite variables in the second plot we see a slow increase, which may be due to reconstructing on background and being unable to throw them out without the use of other apparatuses, but still remains relatively flat.

    Once dead time is taken into account, we don't seem to be losing anything at 8uA as opposed to 7uA, though it appears we do lose a bit going to 9uA.
