One of the alternative ‘dry’ methods for spent nuclear fuel (SNF) reprocessing is the plasma mass separation technique. This letter describes the first experiments that demonstrate the fundamental feasibility of a plasma mass separation approach in crossed electric and magnetic fields in collisionless mode. The Ag + Pb mixture was used to simulate the heavy (>235 u) and light (<150 u) components of the SNF. The Ag + Pb mixture was transformed into a plasma jet and ejected along the magnetic field. The action of the electric field caused the deposition of mixture components on the substrate in the form of localized spots. The estimated separation factor was of 35.

乏核燃料（SNF）后处理的另一种“干”方法是等离子体质量分离技术。这封信描述了第一批实验，这些实验证明了在无碰撞模式下在交叉电场和磁场中使用等离子体质量分离方法的基本可行性。Ag + Pb混合物用于模拟SNF的重组分（> 235 u）和轻组分（<150 u）。Ag + Pb混合物转变成等离子流，并沿磁场喷射。电场的作用导致混合成分以局部斑点的形式沉积在基板上。估计的分离因子为35。
