Coaxial lower hybrid plasma source

Abstract

We report the development of a coaxial radio frequency plasma source capable of producing pulsed plasmas of moderately high density (10(13)-10(14) cm(-3)). This device may be useful either as a general purpose laboratory plasma source or as an auxilliary source for a variety of fusion applications, such as providing target plasmas for mirror machines or producing cold plasma blankets to help isolate the hot plasma core of a toroidal plasma from the walls.
