The purpose of the experiment is familiarization with the construction and operation of compensated boron-lined ionization chambers, which are frequently used as nuclear instrumentation detectors. Basic principle of chamber compensation are explained and demonstrated practically in a mixed neutron and gamma radiation field. Measurements of compensated ionization chamber response linearity are performed at different degrees of compensation.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
