Abstract
In this paper the form of the saturation curve is investigated theoretically and experimentally. It is shown that saturation curves taken under different conditions on a parallel plate ionization chamber are transformed into a single general curve when plotted in terms of a dimensionless product of the several variables. The experimental work utilized an ionization chamber with thin foil electrodes. A coin-shaped region between the foils was ionized by a beam of fast electrons. Dose rates up to 100 000 e.s.u./cm3 × sec could be attained. It is shown that very high ionization intensities can be measured in a parallel plate chamber, provided the spacing of the plates is small.
