Abstract
A tunable frequency pulse generator capable of providing high energy pulses having an in-line construction includes an annularly shaped spark gap and a movable insulator support which includes a conductive sleeve that varies the resonant frequency of the generator. The input voltage is connected to the resonant element through a central aperture provided in the spark gap rings for high efficiency operation.
Claims5
A tunable radio frequency generator for providing high energy pulses comprising in combination:
- a. an elongated resonant cavity having an open end and an essentially closed end;
- b. insulator means for varying the resonant frequency of said generator, said means adapted to movably cooperate with said cavity open end to vary the distance between said open end and said closed end and having an inwardly extending portion, said inwardly extending portion being movable along the longitudinal axis of said cavity and including support means;
- c. an elongated resonant element centrally disposed within said resonant cavity, one end thereof being slidably received by the support means of said insulator means for changing its effective length, said resonant element being provided with input receiving means at its other end proximate the longitudinal axis thereof;
- d. switching means disposed on said other end of said resonant element and connected to said closed end of said resonant cavity;
- and
- e. input terminal means adapted to be coupled to a source of pulsed DC voltage and including an electrically conductive means for providing a conductive path to said resonant element input receiving means.
