摘要:

ITER ICRF系统相对于现代设备上现有系统的复杂性将有所增加,DEMO也是如此。积累的经验对设计ICRF系统的DEMO有很大的帮助。本文介绍了演示ICRF天线和一些相关部件的预概念设计的现状。虽然在许多方面与ITER系统非常相似,但在某些设计解决方案中,我们不得不采取替代路线,以便能够适应DEMO特定。关键点之一是所需ICRF加热性能所需的环形天线范围,通过将天线分成两半并进行适当安装来实现。迄今为止最大的ICRF天线在RAPLICASOL和相关的挑战建模。计算结果以TOPICA为基准。最新模型的分析结果和展望未来的步骤。

英文摘要:

The ITER ICRF system will gain in complexity relative to the existing systems on modern devices, and the same will hold true for DEMO. The accumulated experience can help greatly in designing an ICRF system for DEMO. In this paper the current status of the pre-conceptual design of the DEMO ICRF antenna and some related components is presented. While many aspects strongly resemble the ITER system, in some design solutions we had to take an alternative route to be able to adapt to DEMO specific. One of the key points is the toroidal antenna extent needed for the requested ICRF heating performance, achieved by splitting the antenna in halves, with appropriate installation. Modelling of the so far largest ICRF antenna in RAPLICASOL and associated challenges are presented. Calculation are benchmarked with TOPICA. Results of the analysis of the latest model and an outlook for future steps are given.
