heal.abstract	We present a new parallel code for electron gun, beam tunnel and collector simulation. It is a three-dimensional, electrostatic, self-consistent electron trajectory code. For a conventional gyrotron, the code can be used to study effects associated with deviations from cylindrical symmetry, such as those produced by non-uniform electron emission from the cathode, misalignments between the mechanical and the magnetic axes, etc. In addition, it can handle fully three-dimensional geometries (with dependencies on the polar angle), such as can be found in the case of a sheet beam for a quasi-optical gyrotron. The code has already been used in order to study the effects associated with azimuthally non-uniform emission from the cathode of the coaxial gyrotron assembly of FZK; we present the results of the simulations. © 2005 American Institute of Physics.	en
