Types of Primary Electrons Sources for Terahertz Cold-Cathode Magnetron 'Firing'

摘要

@@ In this communication we have examined the primary electron sources for initiating the pulsed terahertz cold-secondary electron emission cathode SWMs. The capability of these sources emitting and injecting the required start up current is evaluated. The causes for an initiation delay and other factors associated with setting the steady oscillation mode at different side cathode currents are elucidated. Pulsed equal-cavity anode-block and thermionic-cathode magnetrons operating in the non-π-mode, i.e.the surface wave magnetrons (SWM) were designed and later studied over a frequency range of 35 to 375 GHz at A.Ya.
