描述了用大角度（１７８．２°）伴随α粒子方法测量绝对Ｄ－Ｔ 聚变中子产额及其校对实验。为此，设计和加工了一套三叉管校对靶室。α粒子探测器分别置于与Ｄ＋ 束成９０°、１３５°和１７８．２°的方向上。测量和比较了三个方向的α粒子谱和绝对中子产额。分析了实验误差来源。并对实验结果进行了讨论。
Describes the measurement of absolute D-T fusion neutron yield with a large angle (178.2 °) with the alpha particle method and its proofreading experiments. To this end, a trigeminal tube proofing target chamber was designed and fabricated. The alpha particle detectors are placed in directions of 90 °, 135 ° and 178.2 ° with the D + beam, respectively. The α-particle spectra and absolute neutron yields in three directions were measured and compared. The source of experimental error is analyzed. The experimental results are discussed.
