Description
Summary:	Abstract. This thesis presents the results of a study developed in a sub‐millimeter spark‐gap. For developing the study, a coaxial pulse generator with an internal spark‐gap was constructed. The design and construction processes and theoretical design parameters of the coaxial generator are presented and discussed. In the design and experimental processes, electrostatic‐, electromagnetic‐ and transmission line‐simulations were carried out, which are described here. Laboratory tests for different gases at different pressure‐distance conditions were carried out, and based on these results some important gas discharge parameters were calculated, evaluated and discussed. The experimental results obtained in the present research work were compared and validated with some of most accepted theoretical and empirical models. Additionally, some models based on the classical ones were proposed in this work and validated by means of simulations and laboratory tests. In this thesis work, a simplified transmission line model of a pulse generator, including its spark‐gap, is also proposed and validated. Based on this model, a generator for a specific application was design, constructed and tested, as it is described in the last part of this thesis.
