A. I. Smolyakov, A. Sabo, P. Yushmanov, S. Putvinskii

摘要:

得到了近轴磁喷管中磁化等离子体的准中性加速问题的精确解。结果表明,具有局部极大值的非单调磁场是形成准中性加速势结构的必要条件。由于在音速点的正则性条件的约束而发生的加速势的全局性质被强调,并讨论了这种解决方案的性质的情况下,一般多方状态方程的电子。

英文摘要:

Exact solutions for quasineutral plasma acceleration of magnetized plasma in the paraxial magnetic nozzle are obtained. It is shown that the non-monotonic magnetic field with a local maximum of the magnetic field is a necessary condition for the formation of the quasineutral accelerating potential structure. A global nature of the accelerating potential that occurs as a result of the constraint due to the regularity condition at the sonic point is emphasized and properties of such solutions are discussed for the case of general polytropic equation of state for electrons.
