【摘要】 本文介绍一台用于3.3×10¹²n/s强流中子发生器14MeV中子产额绝对测量的45°偏转半导体符合望远镜。在源强2×10¹⁰—3×10¹²n/s范围内与²³⁸裂变室进行了比对测量,在4.5％的误差内两种方法给出一致的结果。更多还原

【Abstract】 In this paper is introduced a 45°-deflection semiconductor coincidence telescope for neutron yield absolute measurement in a 3.3×1012n/s neutron generator. For neutron yields of 2×1910-3 ×1012n/s, the intercomparison measurements have been made with a 238U fission chamber and the two methods gave identical results within an error of 4.5%.更多还原
