Startup of an Electrodeless RF Discharge in a Toroidal System in Presence of a Low Magnetic Field for Hydrogen

Abstract

Breakdown threshold voltage of an electrode less toroidal discharge has been studied using H- type solenoid coil excited by a 13.56 MHz radio frequency power in absence and in presence of a pre ionizing condition with different pressures, aspect ratio, and axial magnetic field for hydrogen. The breakdown threshold depends on various filling parameters e.g. pre-ionising condition, aspect ratio and magnetic field.
