Abstract

Low jitter, triggered spark gap switches are highly desirable components for a wide variety of High Power Microwave applications. In particular, this switch enables a wide range of new applications ranging from protection circuitry to high power transient arrays that are currently technically infeasible with the considerable jitter associated with high power switches. The device presently under advanced development is a novel triggering scheme using a ferroelectric ceramic as the electron source coupled with a high gas flow rate which allows reliable triggering at low trigger voltages, even at high repetition rates. The switch chamber is tailored to reduce field stresses and provide a low inductance current path with a very compact geometry. The high gas flow rate allows the replacement of the gas in the discharge region within the time scale necessary to sustain the required repetition rates of up to 1000 Hz.
