用1个六参量实验测量了252Cf自发裂变碎片坐标系中子能谱参数(中子谱平均能量和中子谱温度)与裂变碎片之间的关联。两个裂变碎片的能量分别由半导体探测器的脉冲幅度和碎片的飞行时间确定。碎片飞行时间的起始和停止信号分别由半导体探测器和平行板雪崩计数器给出。中子飞行时? A six-parameter experiment was used to measure the correlation between neutron spectrum parameters (mean energy of neutron spectrum and neutron spectrum temperature) and fission fragments in 252Cf spontaneous fission fragment coordinate system. The energy of the two fission fragments is determined by the pulse amplitude of the semiconductor detector and the flight time of the fragments, respectively. Fragment time of flight start and stop signals are given by semiconductor detectors and parallel plate avalanche counters, respectively. Neutron flying?
