Abstract
A neutron detector comprises a gas-filled dielectric shell, preferably a glass balloon, having opposite electrodes. An electric field is established whereby ionizing particles may be detected via ionization and current flow in the gas, using a pulse height analyzer or other conventional means. The dielectric shell preferably has low gas permeability and a bulk resistivity in the range of 108 to 1017 Ω-m, and is preferably in the millimeter to centimeter size range. Multiple balloons may be arranged in parallel or may be individually addressable by the detector electronics.
