number of electrons in 1 second

[math] 50ps \times 100A \times 120Hz \times \frac{1\cdot e^-}{1.6\cdot 10^{-19}C} = 0.375 \cdot 10^{13} \frac{e^-}{sec} [/math]

number of gammas in 1 second

[math]10^{-3} \frac{\gamma /MeV}{e^-/r.l.} \times 2 \cdot 10^{-4} r.l. \times 44 MeV \times 0.375 \cdot 10^{12} \frac{e^-}{sec}=0.3 \cdot 10^{7} \frac{\gamma}{sec}[/math]
