Abstract

Since the first plasma operation in 2015, the superconducting fusion experiment Wendelstein 7-X has successfully completed four experiment campaigns (OP1.1, OP1.2a, OP1.2b, and OP2.1). The machine maintenance phase was completed at the end of January 2024, followed by the commissioning of W7-X. The start of the scientific plasma operation phase OP2.2 is planned for September 2024. The trigger-time-event (TTE) system is used by the central control systems, the technical components, and the diagnostics of W7-X for their time synchronization, for processing events, and for generating and receiving trigger signals. These use cases make it necessary to adapt the TTE system to the changing requirements of users. After an introduction to the functions and structure of the TTE system, this contribution describes the current expansion status of the TTE system and the planned modifications and expansion of the hardware and software of the TTE system. Finally, the current status of the planned work on the TTE system for the upcoming W7-X operational phase OP2.2 is presented. The contribution ends with a summary.

W7-X 试验触发-时间-事件系统的新发展

自2015年首次等离子体运行以来，超导聚变实验Wendelstein 7-X已经成功完成了四个实验运动（OP1.1、OP1.2a、OP1.2b和OP2.1）。机器维护阶段在2024年1月底完成，随后是W7-X的调试。科学等离子体操作阶段OP2.2计划于2024年9月开始。触发-时间-事件（TTE）系统由中央控制系统、技术组件和W7-X的诊断系统用于时间同步、处理事件以及生成和接收触发信号。这些用例使得有必要使TTE系统适应不断变化的用户需求。在介绍TTE系统的功能和结构之后，本文描述了TTE系统的当前扩展状态以及TTE系统硬件和软件的计划修改和扩展。最后，介绍了即将到来的W7-X作战阶段OP2.2的TTE系统计划工作的现状。文章以摘要结尾。

期刊介绍： The IEEE Transactions on Nuclear Science is a publication of the IEEE Nuclear and Plasma Sciences Society. It is viewed as the primary source of technical information in many of the areas it covers. As judged by JCR impact factor, TNS consistently ranks in the top five journals in the category of Nuclear Science & Technology. It has one of the higher immediacy indices, indicating that the information it publishes is viewed as timely, and has a relatively long citation half-life, indicating that the published information also is viewed as valuable for a number of years. The IEEE Transactions on Nuclear Science is published bimonthly. Its scope includes all aspects of the theory and application of nuclear science and engineering. It focuses on instrumentation for the detection and measurement of ionizing radiation; particle accelerators and their controls; nuclear medicine and its application; effects of radiation on materials, components, and systems; reactor instrumentation and controls; and measurement of radiation in space.
