Abstract

A detail parametric study of space charge effect related to coaxial insert of 2 MW, 140 GHz coaxial gyrotron is discussed in this manuscript. Corrugation is done in the coaxial insert to minimize the Ohmic wall loading. The geometry of corrugated coaxial insert seriously affects the space charge effect in a gyrotron. Space charge effect is very critical especially for multi-megawatt high frequency gyrotrons. Considering all these facts,a detail parametric study of coaxial insert is performed for 140 GHz coaxial gyrotron in this article

Keywords: Coaxial; space charge effect; coaxial insert
