Abstract

The 2D axisymmetric code DAPHNE has been developed for the design of the magnetron injection guns used in gyrotrons. It is based on the domain decomposition technique and the finite element method to solve the Poisson equation in 2D cylindrical (z,r) geometry. This phase of the calculations is carried out entirely by the existing modules of the ASTRID programming environment. The particle trajectories are then determined by using the standard particle in cell (PIC) scheme. Several aspects of the numerical model used in DAPHNE are detailed.
