利用掺杂层研究磁化靶中的能斯特效应
Nernst effects study using dopant layer on magnetized target
摘要
Abstract
The two-layer magnetized liner target offers an alternative approach to magnetized target fusion implosions by incorporating high atomic number(Z)materials in the innermost layer to mitigate magnetic flux losses caused by Nernst effects and reduce ignition requirements.However,the inclusion of high-Z materials may lead to increased radiation losses due to mixing.This preliminary research on magnetized liner inertial fusion(MagLIF)utilizes germanium(Ge)doped with CH as a high-Z substitute in the liner to isolate the effects of magnetic Nernst advection and mixing.Compared to one-layer targets,the two-layer configuration demonstrates significant increases in temperature and magnetic flux,resulting in a 154%improvement in fusion yield.Different concentrations of CH dopant are introduced into the inner layer of Ge,and the effects of CH concentrations on fusion yield are analyzed.The study shows that using low concentration CH-doped Ge as inner layer of liner can enhance fusion yield.关键词
