聚变反应时间历程的双峰结构测量
Measurement of two-peak structure in fusion reaction history
摘要
Abstract
The relationship of the roughness degree of ablation shell and the two peaks of fusion reaction rate was analyzed. We developed a system for fusion reaction history measurement with high temporal resolution, and applied this system to the SG-Ⅲ prototype for measuring fusion reaction rate. Fusion reaction rate history was measured for the first time with deuterium-tritium filled targets under neutron yields of about 1010. We anatomized possible influence factors during fusion reaction rate's measuring. The two peaks of reaction rate can be obtained from the simulation results, and have been confirmed with the experimental results. It is found that neutrons in our experiment are generated by the first peak which is called the shock peak. The simulation and experimental results can provide strong technical support for the research on fusion reaction rate in inertial confinement fusion.关键词
