Abstract
A fission chamber neutron detector which is both gamma and alpha compensated. The alpha compensation is provided by inclusion of a low neutron cross section, alpha particle emissive isotope within the gamma compensation portion of the fission chamber.
Claims4
A fission chamber neutron detector comprising, a neutron sensitive volume which volume includes a high neutron cross section fissionable material and a predetermined gas fill with at least two electrical signal electrodes within the neutron sensitive volume, and a gamma and alpha signal compensation volume which volume includes a low neutron cross section alpha particle emissive isotope and a predetermined gas fill, with at least two compensation electrical signal electrodes within the compensation volume, whereby the respective volume output signals are combinable to give a resultant gamma and alpha compensated signal.
