Abstract

Abstract

Fusion reaction bang time is an important parameter for measuring compression during the implosion in inertial confinement fusion experiment. A system for fusion reaction bang time measurement with high temporal resolution was developed at the SG-Ⅲ prototype. Through the introduction of timing fiducial, the fusion reaction bang time for different CH ablation layer thickness was obtained. For the first time, fusion reaction bang time was measured for deuterium-tritium (DT) filled targets. The results indicate that the fusion reaction bang time is 0.7~1.0 ns after laser pulses, and increasing the thickness of CH or the pressure of DT gas leads to delay of the fusion reaction bang time.
