# FC analysis using ADC channel current distribution

For each ADC channel:

For distribution over all beam pulses:

# FC analysis using pulse by pulse ADC channel mean value distribution

For each beam pulse:

For distribution over all beam pulses:

Here is:

1. ADC# = bridge#

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

Some examples of ADC mean value distribution. Here are:

1. x axis: ADC mean value for one pulse

2. y axis: number of pulse w/ that ADC mean value

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).
