There are three basic geometries for multigap thyratrons at the present time, and these are reviewed in terms of the constraints imposed by Paschen's Law. Practical examples of each of the three geometries are given and those thyratron characteristics which are a direct result of the choice of geometry are discussed. Performance data are presented for a two-gap thyratron, the CX 1725, and for two four-gap thyratrons, the CX2024 and the CX2025. The basic characteristics of multigap thyratron commutation are briefly discussed, and evidence in support of a simple model is presented. Finally, the results of a recent comparison between the reverse current conduction charactersitics of a hollow anode multigap thyratron and a double-ended multigap thyratron are presented.
