摘要：Micro neutron detectors include relatively small pockets of gas including aneutron reactive material. During use, under a voltage bias in a neutron environment,neutron interactions in the neutron reactive material are seen to occur. Ultimately,
electron-ion pairs form and positive ions drift to a cathode and electrons to the anode.The motion of charges then produces an induced current that is sensed and measurable,thereby indicating the presence of neutrons. Preferred pocket volumes range from a fewcubic microns to about 1200 mm; neutron reactive materials include fissionable, fertile orfissile material (or combinations), such as U, U, U, Th, Pu, B, Li and LiF; gasses include oneor more of argon, P-10, He, BF, BF, CO, Xe, CH, CH, CH, CF, CH, dimethyl ether, CHand CH.Arrangements include two- and three-piece sections, arrays (including or not triadscapable of performing multiple detecting functions) and/or capillary channels.
