摘要
为了测量惯性约束聚变实验中聚变反应的时间过程,提出了一种高时间分辨的聚变反应历程测量系统设计。该系统主要由闪烁体及鼻锥、光学成像系统和条纹相机系统三部分组成。用于能量分别为2.45MeV和14.03MeV的聚变中子测量时,系统的时间分辨分别优于55ps和40ps,对应的测量下限中子产额分别为1.5×109和4×108。
In order to accurately measure the history of fusion reaction for experimental study of inertial confinement fusion, we advance the design of a fusion reaction-history measurement system with high temporal resolution. The diagnostic system is composed of plastic scintillator and nose cone, an optical imaging system and the system of optic streak camera. Analyzing the capability of the system indicated that the instrument measured fusion reaction history at temporal resolution as low as 55ps and 40ps correspond to 2. 45MeV DD neutrons and 14. 03MeV DT neutrons. The instrument is able to measure the fusion reaction history at yields 1.5 ×10^9 DD neutrons, about 4×10^8 DT neutrons are required for a similar quality signal.
