Simulation of magnetic field profile in 2.45 GHz microwave ion sources

عنوان دوره: اولین دوره بین المللی و بیست و هشتمین دوره ملی (1400)
In this paper, the required magnetic field produced by solenoids is simulated for microwave ion sources in COMSOL software. As these sources are categorized in two type of electron cyclotron resonance ion source and microwave discharge ion source, three main parameters such as number of coils, current and coils distance are important to investigate and achieve the field profile. Also, the required magnetic profile is optimized for ECR ion source by increasing the number of solenoid to three. The powered current for simple magnetic mirror field in ECRIS, optimized ECRIS and MDIS are 95, 170 and 90 ampere and the distance for mirror length are achieved as 16, 16.5 and 20 cm, respectively.
