Linear Thyratron.
Abstract
A linear configuration thyratron was investigated experimentally and theoretically. Advantages of this configuration are lower inductance and the capability of increasing current capability by increasing the length of the device without increasing current density or inductance. The experimental device used a 10-cm-long dispenser type cathode a baffled grid and an auxiliary grid. Several modifications were made improving vacuum quality, voltage-standoff or switching speed. The discharge volume could be analyzed using several viewing ports. Using the auxiliary grid, the discharge ignited uniformly over the whole length of the device, proving the linear concept. The distribution of the electron density was measured time resolved using Hook spectroscopy. The data were in good agreement with a numerical code using a spatial grid and time resolved solutions of the Poisson equation. The electrons were represented with normalized spatial densities (macro-electrons) and their motion calculated using Monte Carlo techniques and the appropriate elastic and inelastic collision cross sections.
