摘要

欧洲聚变项目（EUROfusion）内的欧洲 DEMO（EU-DEMO）反应堆研究旨在开发聚变发电厂概念。大型托卡马克装置需要辅助加热功率，现阶段由电子回旋加速器（EC）加热系统提供，预计功率可达 130 兆瓦，用于加热不同区域的等离子体、抑制不稳定性以及支持升压和降压阶段的可能性。该系统目前的概念设计基于 2 兆瓦同轴腔陀螺仪源、使用环形波纹波导和准光疏散多波束传输线的传输线以及位于赤道端口的镜面天线。为了创建一个模块化系统，这些光源被分成 "群"，其功率在准光学传输线中合并，直至托卡马克建筑，在那里它们被分割并作为单波导进行传输。在发射器中，它们在发射镜上再次组合在一起，以节省育种毯的开孔空间。目前的欧共体加热系统具有一定的灵活性，能够适应不断变化的设计准则。本文介绍了该系统的开发情况。

Conceptual Design of a Modular EC Heating System for EU-DEMO

The European DEMO (EU-DEMO) reactor studies within EUROfusion aim to develop a fusion power plant concept. The large tokamak device needs an auxiliary heating power which, at the present stage, is provided by the Electron Cyclotron (EC) heating system with up to 130 MW foreseen to reach different regions of plasma for heating, suppression of instabilities and the possibility to support ramp-up and ramp-down phases. The present conceptual design of the system is based on 2-MW coaxial-cavity gyrotron sources, a transmission line using both circular corrugated waveguides and quasi-optical evacuated multi-beam transmission lines, and mirror antennas located in the Equatorial Port. In order to create a modular system, the sources are grouped in “clusters”, whose powers are combined in the quasi-optical transmission line, up to the tokamak building, where they are split and routed as single waveguides. In the launcher, they are combined together again on the launching mirrors, to save space for the apertures in the Breeding Blanket. The present EC heating system has a certain flexibility to adapt to changing design guidelines. The development status of the system is presented.
