Hand calculation on electron rate

At full current on Faraday cup 1 we have 1201 nVs/ADC channel.

[math]\frac{1201~nVs}{50 \Omega} = 24~nAs = 24~nC[/math]

charge rate under 300 Reprate: [math]300 \times 24~nAs = 7200~nC = 7.2 \frac{\mu C }{ s}[/math]


[math] \frac{7.2 \times 10^{-6}\frac{ C }{ s}} {1.6 \times 10^{-19} C} = 4.5 \times 10^{13}[/math]
