Description

This work investigates the feasibility of generating electron cyclotron resonance in an ion source by replacing the conventional solenoid-produced axial magnetic field with the axial magnetic field of a selected resonant cavity mode. The study focuses on the electromagnetic design of the cavity, the formation of the required axial field distribution, and its capability to establish resonance and confine charged particles in the discharge region. Field characteristics of the cavity mode are analyzed and compared with those of the traditional solenoid scheme in terms of magnetic field profile, resonance condition, and confinement potential. Preliminary results indicate that the cavity-based approach can provide an axial magnetic field suitable for electron cyclotron resonance and offers a promising alternative for compact plasma source design. This study provides a basis for further optimization of cavity configuration and experimental validation in high performance ion sources.
