TI - Electromagnetic Simulation of "plasma-shaped" Plasma Chamber for Innovative ECRIS J2 - Proc. of ECRIS2020, East Lansing, MI, USA, 28-30 September 2020 CY - East Lansing, MI, USA T2 - International Workshop on ECR Ion Sources T3 - 24 LA - english AB - The plasma chamber and injection system design play a fundamental role in ECRISs with the aim to obtain an optimized electromagnetic field configuration able to generate and sustain a plasma with a high energy content. In this work we present the numerical study and the design of an unconventionally-shaped cavity resonator* that possesses some key advantages with respect to the standard cylindrical cavities, usually adopted in ion sources setups. The cavity geometry, whose design has been completed on January 2020, has been inspired by the typical star-shaped ECR plasma, determined by the magnetic field structure. The chamber has been designed by using the commercial softwares CST and COMSOL, with the aim to maximize the on-axis electric field. Moreover, a radically innovative microwaves injection system, consisting in side-coupled slotted waveguides, has been implemented, allowing a better power coupling and a more symmetric power distribution inside the cavity with respect to the standard rectangular waveguides. This new ’plasma-shaped oriented’ design could relevantly improve the performances of the ECRISs while making more compact the overall setup.
