For each beam pulse:

For distribution over all beam pulses (assuming it's Gaussian):

Here is:

1. ADC# = bridge#

2. Pulse# = ReadOut# = Entry# = Event#

Below is the plot of the charge in Faraday cup (pC) as a function of magnet current (vertical axis, A) (basically magnetic field) and ADC (horizontal axis).
