A 2 Cavity Klystrom has the following parameters: $V_{0}=1000 \mathrm{~V}, R_{0}=30 \mathrm{k} \Omega$, $I_{0}=20 \mathrm{~mA}, f=2 \mathrm{GHz}, d=1 \mathrm{~mm}, L=4 \mathrm{~cm}, R_{s h}=30 \mathrm{k} \Omega$. (a) Find the input gap voltage to give maximum voltage $V$ ?
Explanation
The input gap voltage is half of the cathode voltage to give maximum voltage gain in a Klystron amplifier.
