摘要:

介绍了气动磁镜实验装置(ALIANCE-T)的离子回旋共振加热(ICRH)系统天线的初步设计方案。目的是进一步提高等离子体参数和约束;采用了有限元分析软件COMSOL计算磁场分布,并据此确定ICRH慢波加热天线的共振频率和发射位置;通过HFSS天线仿真得到天线本身的阻抗,并结合数值计算得到等离子体的阻抗,从而设计相应的匹配电路。ICRH天线初步设计将为ALIANCE-T辅助加热提供合理的方案建议。

Abstract:

The preliminary design scheme of ion cyclotron resonance heating (ICRH) system antenna of the gas dynamic trap experimental device ALIANCE-T (Axisymmetric Linear Advanced Neutron Source-Test) is introduced. The purpose is to improve the plasma parameters and confinement. The finite element analysis software COMSOL is used to calculate the magnetic field distribution, which determines the resonant frequency and emission position of the ICRH slow wave heating antenna. The HFSS antenna simulation is used to obtain the impedance of the antenna and calculate the plasma impedance to design a corresponding matching circuit. This preliminary design of the ICRH antenna will provide reasonable scheme suggestions for auxiliary heating system of ALIANCE-T.
