The decision to build ITER in Europe, at Cadarache, as a joint enterprise of all major partners in international fusion research opens a new era for fusion and is expected to focus a strong world-wide effort towards ITER and ITER-related R&D in fusion physics and technology.ITER, the unique Next Step device in magnetic fusion, aims at demonstrating the scientific and technological feasibility of fusion. A solid basis exists for constructing ITER and physics scenarios, diagnostics and technologies are being developed for the desired operational features and performance.The ITER project will be the central priority of the European and international fusion programmes. It will be put in the context of a broader approach of supporting R&D and preparations of the following step, DEMO. A vigorous European accompanying programme must comprise support to ITER and DEMO oriented activities, in particular fusion reactor technologies, the investigation of concept improvements and the corroboration of the theoretical foundations of magnetic confinement and of relevant technologies. The domestic programme will have a crucial role for securing the human potential needed for ITER and for ensuring a leading position in the competitive developments for ITER and the further development of commercial fusion energy. 相似文献

为保障ITER极向场(PF)电源系统的高实时性控制需求,根据其设备体积大、分布分散等特点,选取了支持多种设备连接拓扑的实时工业以太网现场总线EtherCAT作为ITER PF电源现场层监控系统的数据通讯协议。为研究ITER极向场电源现场层监控系统的实时性,分析了数据帧在几种适合ITER PF整流器单元现场层信号采集与控制的现场总线设备网络拓扑中的传输延时,通过搭建测试平台验证了方案设计的可行性与正确性。在满足控制系统高实时性要求的同时,经对比找出了较为适合的设备网络拓扑来设计ITER PF电源现场层监控系统,也为ITER PF电源的其他子控制系统的拓扑优化提供了借鉴。 相似文献

Hall sensors offer an attractive true non-inductive method of magnetic field measurements for fusion reactors. Their use for steady state magnetic diagnostics of ITER is presently limited by their questionable radiation and thermal stability. Issues of stable and reliable operation in ITER like radiation and thermal environment are addressed by the contribution. Recently, novel Hall sensors, compatible with temperatures up to 200°C, were developed and their radiation stability was tested at LVR-15 experimental fission reactor. Overview of the experimental set-up on LVR-15 reactor is given. Degradation of the sensor’s sensitivity by several tens of percents was observed after neutron irradiation by the total neutron fluence of 2 × 1017 n/cm2 in LVR-15. This level of neutron fluence is comparable to that expected to occur over the whole ITER life time for a sensor location just outside the ITER vessel. The in-situ recalibration techniques are expected to handle the observed degree of Hall sensors performance degradation in ITER environment. 相似文献
