СПЕКТРОМЕТРИЧЕСКАЯ ИОНИЗАЦИОННАЯ КАМЕРА

摘要

FIELD: recording ionizing radiation; metering alpha-particle energies. ^ SUBSTANCE: proposed spectrometric ionization chamber that enables measurement of spectrums of more than one alpha-particle sources including calibration source under similar conditions without intermediate charging of these sources into chamber and preparing the latter to operation has cathode made of similar flat rectangular sections symmetrically disposed relative to chamber axis which mount alpha-particle sources; these cathode sections are electrically insulated from each other and electric field of each cathode section fully covers ionization region produced by alpha-particle source mounted thereon. ^ EFFECT: enhanced measurement accuracy and productivity of ionization chamber. ^ 1 cl, 1 dwg
