Study of an electromagnetic field induced in a cylindrical cavity by ionizing radiation
Abstract
The present work is concerned with describing the phenomena induced in a cylindrical cavity exposed to a high-energy photon flux. On the basis of simplifying assumptions on the excitation current, air conductivity, and cavity wall, one- and two-dimensional models are developed for the electromagnetic field generated in the cavity; the effectiveness of each model is stressed. The study revealed the influence of cavity geometrical dimensions and of air on the variations of the field intensity during photon excitation. A method is described for experimental measurement of the magnetic field, which has made it possible to verify partially the validity of the results obtained and to show the effectiveness of this method in detecting ionizing radiation.
