在欧盟发电厂概念研究中，卡尔斯鲁厄研究中心对用于演示的氦冷偏滤器概念进行了广泛的研究，目标是证明至少在10 MW/m2热通量下的性能。工作涵盖不同的领域，从概念设计到分析，材料和制造问题到实验。与此同时，氦冷却模块式偏滤器概念与射流冷却（HEMJ）已被提出作为参考设计。与埃夫雷莫夫研究所合作，对偏滤器元件进行了制造和高热通量测试，以进行设计验证和原理验证。本文重点研究了钨合金和Eurofer钢支撑结构材料实体模型的制造工艺。对2006年和2007年的高热流密度试验结果进行了总结和讨论。
A helium-cooled divertor concept for DEMO has been investigated extensively at the Forschungszentrum Karlsruhe under the EU power plant conceptual study, the goal being to demonstrate performance under heat flux of 10MW/m2at least. Work covers different areas ranging from conceptual design to analysis, materials and fabrication issues to experiments. Meanwhile, the He-cooled modular divertor concept with jet cooling (HEMJ) has been proposed as reference design. In cooperation with the Efremov Institute, manufacture and high heat flux testing of divertor elements was performed for design verification and proof-of-principle. This paper focuses on the technological study of the fabrication of mock-ups from W/W alloy and Eurofer steel supporting structure material. The high heat flux test results of 2006 and 2007 are summarised and discussed.
