2D simulation of hydrodynamic instability in ICF stagnation phase

A. Sunahara, H. Takabe, K. Mima1999年Fusion Engineering and DesignIF 1.7出版社

AbstractIn the stagnation phase of inertial confinement fusion, hydrodynamic instabilities prevent fuel heating, and fusion neutron yield is reduced. We calculated the neutron yield, fuel temperature, and the energy transport in the stagnation phase. The measured neutron yield of the implosion experiment carried out at this institute (ILE) is compared with the calculated value. The trend of calculation values agrees with that of the experiment.
