Abstract
Small signal gain calculations on a travelling-wave gyrotron amplifier (gyro-TWA) show that for a low density uni-velocity beam, for which space charge forces can be neglected, moderate band widths, between 5% and 20%, can be attained at the expense of basic electronic efficiency. Interaction between the beam and the first four TEon modes of the circular cylindrical waveguide interaction region is considered and, for nil four cases, it is shown that at a given beam voltage mid current level an optimum bandwidth condition exists which is principally governed by the transverse-to-axial velocity ratio of the electrons in the uni-velocity gyrating beam.
