Abstract

This work is aimed at providing directions and suggestions for the design of the Vacuum Feedthroughs (VFTs) for Ion Cyclotron Heating (ICH) system in the Divertor Tokamak Test facility (DTT). To this scope we focused on electromagnetic (EM) numerical simulation of VFTs having different shapes. The analysis of the scattering parameters and the EM fields are merged with the investigation of the effect of the dielectric windows on the characteristic impedance of the radio frequency (RF) transmission line (TL). The results will be used to guide the designer in choosing the layout and shape of the VFTs and the related TLs.

数字地面电视ICH系统的射频建模与馈线设计

这项工作旨在为憩息器托卡马克试验设施（DTT）中离子回旋加速器加热（ICH）系统的真空馈入件（VFT）设计提供方向和建议。为此，我们重点对不同形状的 VFT 进行了电磁（EM）数值模拟。在分析散射参数和电磁场的同时，我们还研究了介质窗口对射频（RF）传输线（TL）特性阻抗的影响。研究结果将用于指导设计人员选择 VFT 和相关 TL 的布局和形状。
