A travelling wave resonant ring accelerator method and apparatus is disclosed which includes a generator of radio frequency source energy and a low dispersion accelerator waveguide interconnected by a microwave bridge network that combines said source energy and said accelerator remnant energy and directs said combined energy to the input of the accelerator waveguide under desired conditions with the bridge balanced. The method and apparatus simultaneously maintain (a) the optimum beam-wave phase relationship in the accelerator waveguide and (b) the correct electrical length of the resonant ring, regardless of wide variations in ambient temperature, by maintaining a balanced bridge condition by automatically adjusting the frequency of the source energy. Electromagnetic interference is avoided by incorporating a high power modulator high voltage switch in a compact coaxial transmission line to provide a contraflow circuit for high current pulses switched and transmitted between a pulse forming network and a pulse transformer. Also disclosed is a fluid-tight dual housing arrangement utilizing a high voltage coaxial connector assembly which includes multiple sliding contacts, between inner and outer conductors of matched individual coaxial transmission lines in each housing, to maintain stress-free electrical connections when large differential longitudinal movements take place between the housings and the accelerator equipment contained therein.
