number of [math]\ e^-/sec\ [/math] on radiator

[math] 50ps \times 50A \times 300Hz \times \frac{1\cdot e^-}{1.6\cdot 10^{-19}C} = 0.75 \cdot 10^{13} \frac{e^-}{sec}[/math]

number of [math]\ \gamma 's/sec\ [/math] after radiator

[math]10^{-3} \frac{\gamma 's}{(e^-\ MeV\ 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]
