Abstract

The free electron laser (FEL) is driven by electron beams with energies ranging from hundreds of kilovolt to hundreds of megavolt. Therefore the efficiency of FEL strongly depends on the beam quality. In this paper we examined the relation between applied voltage and magnetic field at the magnetically insulated cylindrical cold cathode for the high quality electron beam by the numerical analysis. As a result, we knew that the beam widening strongly depended on applied magnetic field and voltage.
