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.

使用済み核燃料(SNF)の再処理における代替的な「乾式」法の一つに、プラズマ質量分離技術がある。本レターは、無衝突モードにおける直交電磁場中のプラズマ質量分離アプローチの基本的な実現可能性を実証する最初の実験について述べるものである。Ag + Pb 混合物は、SNF の重い成分(>235 u)と軽い成分(<150 u)を模擬するために使用された。Ag + Pb 混合物はプラズマジェットに変換され、磁場に沿って放出された。電場の作用により、混合物の成分は基板上に局所的なスポットとして堆積した。推定された分離係数は 35 であった。
