摘要:

基于原子质量分离大量混合物质的能力对于具有高社会影响的各种新兴应用来说似乎是理想的。满足这一目标的一种可能性在于利用旋转等离子体中的质量差效应。除了传统的离心分离之外,旋转等离子体原则上提供了基于质量分离元素的其他方法。单离子轨道表明,均匀磁化等离子体柱中的离子径向质量分离可以通过在柱上施加定制的电势分布或通过在柱内驱动旋转磁场来实现。此外,磁压力和离心效应可以以非均匀几何形状组合,以基于沿着场线的质量分离离子。这些分离方案的实际应用取决于在等离子体柱内产生期望的电场和磁场配置的能力。

英文摘要:

The ability to separate large volumes of mixed species based on atomic mass appears desirable for a variety of emerging applications with high societal impact. One possibility to meet this objective consists in leveraging mass differential effects in rotating plasmas. Beyond conventional centrifugation, rotating plasmas offer in principle additional ways to separate elements based on mass. Single ion orbits show that ion radial mass separation in a uniform magnetized plasma column can be achieved by applying a tailored electric potential profile across the column, or by driving a rotating magnetic field within the column. Furthermore, magnetic pressure and centrifugal effects can be combined in a non-uniform geometry to separate ions based on mass along the field lines. Practical application of these separation schemes hinges on the ability to produce the desirable electric and magnetic field configuration within the plasma column.
