Description
High-abundance stable isotopes of nickel possess broad applications and significant demand, which can be prepared using the electromagnetic separation method. The core equipment of an electromagnetic separator for isotope separation is the ion source. To improve the heating efficiency of the traditional Calutron ion source, an electromagnetically induced heating-type ion source is designed. The heating performance of the crucible depends on the configuration of the induction heating power supply and the process design of the inductor. Based on theoretical empirical formulas and electromagnetic field theory, a finite element simulation software, COMSOL Multiphysics, is used to establish a Calutron ion source model. By studying factors affecting heating efficiency.such as the current magnitude, number of turns, spacing of the energized coil, distance between the coil and the crucible, and frequency of the alternating current—electromagnetic-thermal multiphysics coupling simulations are conducted. This helps determine the parameter configuration of the induction heating system power supply. Finally, the inductor design is optimized through orthogonal experiments. The research results can provide practical engineering guidance for the design of electromagnetic induction heating systems in Calutron ion sources.
