Radiation losses in a dense high-temperature hydrogen plasma containing impurities

Yu.I. Galushkin, V.I. Kogan1971年被引用 6Nuclear FusionIF 3出版社

The authors calculate the radiation intensity of a hydrogen plasma containing small amounts of impurity in the form of bare nuclei and hydrogen-, helium-, lithium- and beryllium-like ions with a nuclear charge Z in the range 5 ≤ Z ≤ 18. They consider electron concentrations of 1016 ≤ ne ≤ 1020 cm−3 and electron temperatures of 0.05 ⩽ kT/Z2 Ry ⩽ 3 (Ry = 13.6eV), which are typical of the radiating zone of the plasma focus. The results show, among other things, that the radiation from the impurities may substantially limit the life-time of the high-temperature zone in the plasma focus.

著者らは、水素プラズマ中に微量の不純物として存在する裸の原子核および水素様、ヘリウム様、リチウム様、ベリリウム様イオン(核電荷Zは5 ≤ Z ≤ 18の範囲)からの放射強度を計算する。電子濃度は1016 ≤ ne ≤ 1020 cm−3、電子温度は0.05 ⩽ kT/Z2 Ry ⩽ 3(Ry = 13.6 eV)を考慮しており、これらはプラズマフォーカスの放射帯に典型的な値である。結果は、とりわけ、不純物からの放射がプラズマフォーカスにおける高温帯の寿命を大幅に制限し得ることを示している。
