TRANSIENT RESPONSE OF CERTAIN ION CHAMBER TO SHORT RADIATION PULSES,
Abstract
A procedure for uncoupling the charge transport and electric field equations under certain re strictions of no recombination, and dose rate limitation, in a parallel plate ion chamber is given. A solution to the first uncoupled trans port equation for a flat-topped ionization pulse, not neglecting diffusion, is obtained by finding the appropriate Green's function, and the sub sequent current densities and external circuit current are derived. The usual assumption of neglecting diffusion is shown to be valid for most cases involving ion transport by an examina tion of the general form of the external chamber current. Variations of the external circuit current with the radiation pulse width, and ratio of negative to positive ion mobilities are given. An attempt to ''fit'' an observed record is discussed. (Author)
