THE PRELIMINARY APPROACH OF A MODELICA-BASED SINGLE-PARTICLE ACCELERATOR SIMULATOR

抄録

This work uses the Modelica language to simulate a tandem accelerator with only one single particle based on parameters from the 2×1.7 MV tandem accelerator (under construction) at Harbin Engineering University, which is expected to provide heavy negative ions like Cu-, Fe-, Ni-, etc. for research in the nuclear material field. The work focuses on the beam optics system of the accelerator including accelerating tubes, magnets and lens components and establishes simplified models of these components in the open-source platform OpenModelica. The system is capable to simulate the trajectory of a single particle at low speeds moving in the tandem accelerator by assembling all the components into a complete system in a visualized layout. By manipulating parameters, different kinds of particles can be simulated. It proves that the calculation results of the simulator are quantitively comparable with the results from assessed code used for the accelerator evaluation and can be used to simulate the accelerator for different purposes.
