Abstract

We present a new parallel code for gyrotron beam tunnel simulation. It is a three dimensional, electrostatic, self-consistent and trajectory code. For a conventional gyrotron it can be used to study the effects associated with deviations from cylindrical symmetry, such as those produced by non-uniform electron emission from the cathode, mis-alignments between the mechanical and the magnetic axes, etc. In addition, it can handle fully three-dimensional geometries (with dependence on the polar angle), as in the case of a sheet beam for quasi-optical gyrotron.
