| 摘 要： | 聚变反应速率是表征惯性约束聚变热核反应的重要参数，为测量聚变反应速率，研制了一套由闪烁体及鼻锥部分、光学系统和条纹相机组成的测量系统。在神光Ⅲ原型装置上利用新研制的聚变反应速率测量系统进行了聚变反应速率测量。在DT中子产额约为1010条件下,首次获得了聚变反应速率随时间的变化过程。对影响聚变反应速率测量的相关因素进行详细分析后表明,系统的时间分辨力优于30 ps。

| Abstract: | Fusion reaction rate is an important parameter for measuring compression during the implosion in inertial confinement fusion experiment. We have developed a system for fusion reaction history measurement with high temporal resolution. The system is composed of plastic scintillator and nose cone, optical system and streak camera. We have applied this system on the SG-Ⅲ prototype for fusion reaction rate measuring. For the first time, fusion reaction rate history have been measured for deuterium-tritium filled targets with netrons yields about 1010. We have anatomized possible influence factor during fusion reaction rate measuring. It indicates that the instrument measures fusion reaction bang time at temporal resolutions as low as 30 ps. |
