The thermonuclear hot-spot

J.P. Somon1972年被引用 7Nuclear FusionIF 3出版社

The expansion of a spherical hot-spot within an infinite D-T medium is examined and the production of thermonuclear energy is calculated through the numerical solution of the plasma-fluid equations in a number of cases. Two kinds of hot-spots are considered in which the ions are initially either hot (ionic H-S) or cold (electronic H-S). The conditions for a positive energy balance and the ignition of a thermonuclear reaction wave are derived. At solid-state density a pulsed fusion reactor requires an energy of 103–104 MJ. Extensions are made to plane and cylindrical H-S and the expansion of a spherical H-S in vacuum. The thermonuclear output is not improved by progressive H-S heating or a decrease in thermal conductivity in a transverse magnetic field.

無限のD-T媒質内における球状ホットスポットの膨張を検討し、いくつかのケースについてプラズマ流体方程式の数値解を通して熱核エネルギーの生成を計算する。イオンが最初に高温(イオン性H-S)または低温(電子性H-S)のいずれかである2種類のホットスポットを考察する。正のエネルギーバランスと熱核反応波の点火の条件を導出する。固体密度では、パルス核融合炉は10³〜10⁴ MJのエネルギーを必要とする。平面および円筒形のH-S、ならびに真空中での球状H-Sの膨張への拡張を行う。熱核出力は、進行性のH-S加熱または横磁場における熱伝導率の低下によって改善されることはない。
