Abstract

A simple formula for plasma frequency reduction factor for a solid cylindrical electron beam in a metallictunnel has been developed by means of a 3-D curve fitting to the standard results of Branch and Mihran withaccuracy > 1.7 per cent, over the parametric regime of normalised beam-radius and beam-filling factor applicablefor linear-beam microwave tubes.  An artificial neural network algorithm was used for the curve-fitting followingthe approach of universal approximation.  The formula is simple and amenable to easy computation, even usinga scientific calculator.
