The mass separation of chemical element mixtures is a relevant task for numerous applications in the nuclear power industry. One of the promising approaches to solve this problem is plasma mass separation. In a recent study, the efficiency of plasma mass separation in a configuration with a potential well and a homogeneous magnetic field was experimentally demonstrated. This article examines the possibility of increasing the distance between the deposition regions of charged particles with different masses by varying the profile of the electric field potential. Such correlation can be considered as the control in a system of active particles. A cylindrical coordinate system is used. The electric field is axially symmetrical, and the magnetic field is directed along the axis of the symmetry. The corresponding mathematical problem was solved in a general way. The criteria for increasing the distance between the deposition areas of the "light" and "heavy" components of the mixture have been formulated. A high sensitivity of particle trajectories to the electric field potential in the region of the pericentres of the trajectories of charged particles was detected. Recommendations for the practical implementation of the optimal spatial separation of ion fluxes are proposed.
化学元素混合物的质量分离是核电工业众多应用中的一项重要任务。解决这一问题的一种有前景的方法是等离子体质量分离。在最近的一项研究中，通过实验证明了在具有势阱和均匀磁场的配置中等离子体质量分离的效率。本文研究了通过改变电场势的分布来增加不同质量带电粒子沉积区域之间距离的可能性。这种相关性可被视为活性粒子系统中的控制。使用柱坐标系。电场是轴对称的，磁场沿对称轴方向。以一般方式解决了相应的数学问题。制定了增加混合物“轻”和“重”组分沉积区域之间距离的标准。检测到粒子轨迹在带电粒子轨迹近心点区域对电场势具有高灵敏度。提出了关于离子通量最佳空间分离实际实施的建议。
