Generation and Improvement of the Gyrotron Electron Beam in a Biased Cusp Magnetic Field.
Abstract
Transition of an electron beam through a biased magnetic cusp field can result in higher perpendicular-to-parallel velocity ratio or lower momentum spread. Analytical relations for the transformation of velocity ratio and momentum spread across the magnetic cusp are derived on the assumption of adiabatic electron motion. A single particle trajectory code is developed to investigate the nonadiabatic electron behavior in two models of a biased cusp magnetic field. After intensive data analysis, some general conclusions are presented on the prospects of generation and improvement of the gyrotron electron beam in a biased cusp magnetic field. (Author)
