托卡马克中ICRH天线的优化设计

摘要

The coupling of the ICRF antenna to the plasma in tokamak is studied by using a plasma slab model and a three-dimensional antenna model. The simulation results show that under the same conditions, the antenna of symmetric current distribution and a long feeder may have more effective power coupling than the antenna of antisymmetric current distribution and a short feeder.%采用等离子体平板模型和三维天线模型数值模拟了托卡马克中 ICRH 天线与等离子体的耦合过程,模拟结果表明在其它实验条件相同的条件下,与反对称电流和馈线端长度短的天线相比,对称电流分布和馈线端长度长的发射天线可获得更有效的功率耦合.
