Title
Further Development Of Microwave Gamma-Ray Ion Chamber
Description
A microwave gamma-ray ion chamber has been developed that measures gamma radiation from 106 to 1010 ergs per gram-hour (carbon) in the presence of a neutron flux of 1010 neutrons per square cm per second. This report discusses the choice of materials, development of a unique vacuum system, and fabrication of chambers suitable for operation at temperatures to 500°C in a high neutron flux. Data are presented on the response of an ion chamber to various ratios of incident gamma, thermal neutron, and fast neutron fluxes.
