Abstract

The FCI (field charge interaction) code is a 2-1/2-d particle-in-cell simulation program dedicated to analyzing and designing high power klystron amplifiers. The code simulates the electron beam motion with cylindrical symmetry by taking into account the space-charge fields, RF-cavity and external focusing magnetic fields. The cavity voltages and the output power are determined by solving the circuit equations self-consistently. Taking the six-cavity, 1.1-MW Phillips YK 1303 klystron as an example, the power of the FCI code is demonstrated. The code´s working area is restricted to the RF-section of a klystron. Examples of simulations compared with measured data are presented.<>
