摘要
本文介绍了ICRF加热的等离子体聚变反应率的计算,并对有关的<σV>-(rf)表达式作了修正。计算结果表明,ICRF等离子体的高能尾部能使反应率增加,有助于把等离子体加热到点火,节省所需要的加热功率。但<σV>_(rf)只在低温、低密度区域增加显著,<σV>_(rf)/<σV>_m随等离子体温度增加而减小,当T=10keV时<σV>_(rf)/<σV>_m大约等于3,当T=20keV时<σV>_(rf)/<σV>_m大约等于1。
A calculation of fusioa reaction rate for the ICRF heated plasma is presented in this paper. The formula for <σV> in the paper presented by Harvery is modified. The reactivity enchancement produced by the high energy tail is examined. This enchancement will help to heat plasma to ignition aad to save auxiliary power required, significant enchancement of the reaction rate is in the range of lower temperature and lower density. The ratio <σV>/<σV>ecreases as the plasma temperature increases. It is about 3 for T=10 keV and about 1 for T=20 keV.
