Characteristics of orotron oscillation and amplification. 2: Linear bunching theory
Abstract
A linear theory of bunching in the orotron is derived in which the electron beam evolves in time via the Boltzmann equation. The theory is used to derive the power radiated by an electron beam subjected to a general longitudinal electric field. It is then specialized to the case of the orotron, in which the electric field is quasiperiodic. The starting current, I sub s, and the electronic tuning transconductance, df/dV, are calculated from the theory. These results are evaluated for the planned Harry Diamond Laboratories orotron experiment at 75 gigahertz and are found to be I sub s = 34.5 milliamperes and df/dV = 0.31 megahertz/volt.
