Spark gaps for grid-cathode protection of pulsed travelling-wave tubes

Show affiliations


The development of a high-speed spark gap for grid-cathode protection of pulsed travelling wave tubes is described. Protection requirements are discussed, together with the interaction of the gap with the associated circuitry. From this it is possible to define the required characteristics of the protection gap. A description is given of how the physical mechanisms of gas discharges are utilised to obtain the desired characteristics.
