Magnetically Insulated Opening Switch Research.

Abstract

We examine the feasibility of an opening switch concept based on magnetic insulation in a coaxial thermionic diode. It is found that the impedance ratio between 'closed' and 'open' states of the diode is marginal for efficient energy transfer via this type of switch. The open, or insulated state of the diode is characterized by current leakage across the magnetic field which is associated with the presence of plasma waves. Keywords included: Magnetic Insulation; Thermionic diode; Opening switch; Plasma waves.
