论文摘要
本文提供了Beklemishev Diamagnetic Trap中血浆平衡的动力学描述，其中基于磁性漂移理论的传统方法不适用于，因为离子在基本非圆形轨道中移动，其直径的直径大约等于diamagnetic Bubble的直径。离子分布函数在无碰撞近似中发现，忽略了磁管电子电流。计算了磁场的径向轮廓，等离子密度，电流密度和压力张量的成分。发现磁管气泡中边界层的宽度从真空磁场计算得出的6至8 Larmor Radii不等。计算绝热的不变式，该磁矩代替了磁矩，该磁矩在Dimagnetic Bubble中并非保守。制定了绝对限制的标准，并且在绝热不变的情况下发现了血浆平衡，并且只有速度的离子满足绝对限制的标准。
The article provides a kinetic description of the plasma equilibrium in the Beklemishev diamagnetic trap, where the traditional approach based on the theory of magnetic drifts is not applicable, since the ions move in a substantially non-circular orbit, the diameter of which is approximately equal to the diameter of the diamagnetic bubble. The ion distribution function was found in the collisionless approximation, neglecting the diamagnetic electron current. The radial profile of the magnetic field, the plasma density, the current density, and the components of the pressure tensor are calculated. It was found that the width of the boundary layer in the diamagnetic bubble varies from 6 to 8 Larmor radii calculated by a vacuum magnetic field. An adiabatic invariant is calculated that replaces the magnetic moment, which is not conserved in the diamagnetic bubble. The criterion of absolute confinement is formulated and the plasma equilibrium is found for the case when the adiabatic invariant is not conserved and only ions whose velocity satisfies the criterion of absolute confinement are trapped.
