摘　　要：建立了直径为30 cm,厚度为5 cm,10 cm,15 cm,20 cm,25 cm二维铝饼装置,利用φ50.8 mm×50.8 mm的BC501液体闪烁探测器开展了不同厚度铝饼的D-T中子穿透能谱实验研究和源中子谱实验研究,获得了不同厚度铝装置的源中子直穿量和穿透率。实验表明穿透率随装置厚度的变化比直穿量要缓,对影响实验测量的因素进行了分析,结果表明这种不一致是由于源中子小角散射引起的。Two-dimension aluminum assembly was established.Their diameters are all 30 cm.The thicknesses are 5 cm,10 cm,15 cm,20 cm and 25 cm,respectively. The energy spectra of penetrative neutron for D -T source were measured for five different thickness assemblies,as well as the neutron energy spectrum of the source.The uncollided neutron and the penetration ratio were obtained. The experiment shows that the penetration radio slowly changed to the uncollided neutron.The factors of experimental measurement influence...
