Glass-panel lithium-6 neutron detector

摘要: A thermal neutron detector includes a planar housing having two glass panels spaced apart by gas-tight seal defining detection chamber. Lithium foils adhered to inner surfaces of the panel emit alpha particles and tritons in response incident neutrons, an inert gas is ionized generate drift electrons. array wires from lithium extends outside Electronic bias applies field voltage between establish electric attract electrons provide large cause electron multiplication. Detection circuitry detects signals generated positive ions away interprets electrical as incidence neutrons on detector.
