一种新的大体积球形正比计数管，最近开发的，用于中子测量。研究了纯N2气体用于热中子和快中子探测，为中子能谱研究提供了新的途径。中子通过N14（n，p）C14和N14（n，α）B 11反应被探测到.该探测器已通过Cf 252和Am 241− Be 9中子源的热中子和快中子探测测试。成功地测量了大气中子，从热到几MeV，与宇宙射线背景分离。文中还对球形正比计数器与现有中子计数器进行了比较。
A novel large volume spherical proportional counter, recently developed, is used for neutron measurements. The pure N 2 gas is studied for thermal and fast neutron detection, providing a new way for neutron spectroscopy. The neutrons are detected via the N 14 (n, p) C 14 and N 14 (n, α) B 11 reactions. The detector is tested for thermal and fast neutrons detection with Cf 252 and Am 241− Be 9 neutron sources. The atmospheric neutrons are successfully measured from thermal up to several MeV, well separated from the cosmic ray background. A comparison of the spherical proportional counter with the current available neutron counters is also presented.
