Title:
中性子比例計数管のためのクエンチガスとしての三フッ化ホウ素
Document Type and Number:
Japanese Patent JP7373035
Kind Code:
B2
Abstract:
A neutron proportional counter (100) is provided. The proportional counter includes a chamber (102) and a gas mixture (110). The chamber (102) includes an anode (104) and a cathode (106). The gas mixture is contained within the chamber and includes at least one neutron sensitive fill gas (112) and a quench gas (114) including BF3. In certain embodiments, the neutron sensitive fill gas can be configured for detection of thermal neutrons (e.g., He-3), fast neutrons (e.g., He-4, H2), or both (e.g., UF6).
