Magnetic Filter-Enhanced Plasma Systems for Sustainable Manufacturing and Quantum Device Engineering

Transverse magnetic filters (TMFs), originally developed for caesium-free fusion ion sources, provide an effective means of controlling electron energy distributions in plasma-assisted manufacturing. This work develops a computational magnetokinetic modelling framework that connects magnetic-field topology to energy utilisation, defect suppression, and process performance across semiconductor, catalytic, and quantum-device applications. Through analytical modelling and Monte Carlo calibration, the framework predicts improvements in energy efficiency and reductions in defect density for representative plasma systems, together with potential energy savings in industrial-scale reactors. The results indicate that a unified magnetokinetic description can capture common transport behaviour across multiple domains while identifying important domain-specific considerations. The proposed framework offers a reproducible computational methodology for analysing magnetic-field-assisted plasma control and is intended to guide future experimental validation.
