I still did not understand this from my previous threads, what is the way to determine the instantaneous voltage across the cavity plates at any given moment, in a klystron I suppose the voltage would be proportional to the arriving electron bunch density which would determine the overall bunch charge strength? I suppose there are additional complexities due to the constant DC component of the passing bunched electron beam?
Does the voltage that forms between the cavity plates which also determines the E field strength in the cavity is proportional to the amplitude/voltage of the cavity input sine amplitude?
I am reading this PDF, on page 7 it talks about cavity shunt impedance,

So a given size cavity has given impedance and the only way to increase the E field strength in the cavity is to increase the voltage/amplitude of the cavity input waveform?
I am asking this because I am curious whether one can get a strong E field in the cavity by powering it from a low impedance, low voltage but very high current source at it's resonant frequency so that the generator and cavity resonant frequency match?
In theory at resonance the cavity impedance should be very low ? allowing for a low voltage high current waveform to create a strong E field within the cavity?
