Abstract

The analysis is based on the relations characterizing charged particles’ motion in the drift approximation (D. V. Sivukhin, in Reviews of Plasma Physics, Ed. by M. A. Leontovich (Consultants Bureau, New York, 1965), Vol. 1, p. 1; B. A. Trubnikov, Introduction toPlasma Theory (Mos. Inzh. Fiz. Inst., Moscow, 1968) [in Russian]). It is noted that the particles can be accelerated using the device proposed in the work (A. V. Timofeev, Sov. J. Plasma Phys. 4, 464 (1978)) for the inverse process of converting the particles’ chaotic motion energy into electric energy. The magnetic field of such a system is similar to that of the rectilinear current-carrying conductor. In the work (A. D. Beklemishev, Phys. Plasmas 22, 103506 (2015)), for particle acceleration, it was proposed to use the magnetic field, which is the superposition of the homogeneous field and the helical field with a varying period. In such a system, the charged particles’ acceleration can be considered to be the result of the Cherenkov resonance interaction of particles with the zero-frequency electric field. During the particles’ acceleration, the resonance conditions can be maintained due to the autophasing process, which is a consequence of the constancy of the corresponding adiabatic invariant (A. I. Neishtadt and A. V. Timofeev, Sov. Phys. JETP 66, 973 (1987)). To ensure these conditions, the helical field period should vary quite slowly along the system’s axis.

交叉场中带电粒子的加速度

摘要

该分析基于在漂移近似中表征带电粒子运动的关系（DV Sivukhin，MA Leontovich编辑的《等离子体物理评论》（纽约，咨询局，1965年），第1卷，第1页； BA。特鲁布尼科夫，《等离子体理论导论》（Mos。Inzh。Fiz。Inst。，莫斯科，1968年，[俄文]）。值得注意的是，所述颗粒可利用在工作（A. V.吉莫弗耶夫，SOV。J.等离子的PHY。所提出的设备来加速4为粒子的混沌运动能转换成电能的逆过程，464（1978））。这种系统的磁场类似于直线载流导体的磁场。在工作中（A. D. Beklemishev，物理等离子22，103506（2015）），建议使用磁场，该磁场是具有变化周期的均匀场和螺旋场的叠加。在这样的系统中，带电粒子的加速度可以被认为是粒子与零频电场的Cherenkov共振相互作用的结果。在粒子的加速度，则谐振条件可以保持，由于自动相位辨识过程，这是相应的绝热不变的恒定性的结果（AI Neishtadt和A. V.吉莫弗耶夫，SOV。物理学。JETP 66，973（1987））。为确保这些条件，螺旋场周期应沿系统轴缓慢变化。
