| 摘 要： | 长中子计数器是在一定的中子能量范围内，中子探测器效率恒定，不随中子能量变化的一种中子探测装置。本工作的长中子计数器为Hanson结构。采用含氢正比计数器与半导体望远镜法，用静电加速器中子源分别为220 keV、500 keV、1.000 MeV、1.403 MeV、3.270 MeV、4.000 MeV与5.000 MeV单能中子束，对本单位制作的BNIF-1长中子计数器进行了刻度。刻度结果表明，在220 keV～5.000 MeV区间，中子探测器效率为2.8810×10-4（1±4.8%）。

| Abstract: | The long neutron counter is a kind of neutron detection instrument, which detector efficiency is a constant in some determined range of neutron energy, and is not changed in accordance with neutron energy. The current long neutron counter is designed based on Hanson structure and produced by China Beijing Nuclear Instrument Factory. With Hydrogen-contained proportional counter tube and semiconductor telescope methods, the current long neutron counter has been calibrated with electrostatic accelerator neutron source: 220 keV、500 keV、1.000 MeV、1.403 MeV、3.270 MeV、4.000 and 5.000 MeV single energy neutron beams. The calibration gives results of detector efficiency: 2.881 0×10-4（1±4.8%） in energy range from 220 keV to 5 000 MeV. |
