Analytical modeling and experimental testing of pressure effects in small cavities coupled to circuitry

Photo-emission currents and their associated electromagnetic fields are generated when photons irradiate any system. When gas-filled cavities are irradiated, photo-ionization and collisional ionization of the gas can produce a background plasma which significantly alters the electromagnetic response within the cavity.^1–3 Previous studies have concentrated on conditions within an irradiated cavity; in this paper we consider the modifications of circuit response caused by x-ray energy photons incident upon a small gas-filled cavity which is an element of an electrical circuit. Such a configuration is present in various practical devices.
