Description
Shot noise, intrinsic to electron beams, is the cause of statistical fluctuations in
radiation generated by quasi-Cherenkov generators operating in stationary and non-stationary regimes. Radiated power and instability time growth are
the main output parameters
characterizing the dynamics of electron beam interacting
via the radiation field.
Shot-noise related fluctuations of radiated power and instability time growth impose appreciable
limitations on the possibility of coherent summation of
electromagnetic oscillations from several quasi-Cherenkov generators operating in microwave and terahertz ranges [1,2]. The optimal conditions minimizing the spread of the main output parameters have been found
for stationary and non-stationary regimes of quasi-Cherenkov generator operation.
