Abstract The super conducting stellarator Wendelstein 7-X (Bosch et al., 2017) started its first operational phase in October 2015 at the Max-Planck-Institute for Plasma Physics in Greifswald with the goal to verify that a stellarator magnetic confinement concept is a viable option for a fusion power plant, i.e. showing confinement comparable to tokamaks and running in steady state operation. Between 2015 and 2018 the first three experimental campaigns (operational phases) OP1.1, OP1.2a and OP1.2b of the W7-X stellarator have been successfully completed. Roughly 13 Months of operational time have been accumulated and have already shown the impressive capability and reliability of W7-X in achieving the physical and technical goals as set by the project. The working group Device Operation (DO) has implemented an organizational structure and workflow to ensure safe and reliable operation of the W7-X device. DO is responsible for planning and executing the commissioning and operation of the W7-X device. The operations plan is based on the physics planning which is a selection of individual physics proposals keeping in mind the technical limitations of W7-X. The operations plan is iterated between the lead physicists and device operation team (DOT). The “technischer Leiter vom Dienst” (TLvD or Engineer in Charge) plays a central role within the DOT in coordinating and supervising the technical operation of W7-X. To ensure safe and reliable operation of W7-X several procedures have been implemented and improved. This involves commissioning templates, checklists, procedures for e.g. plasma heating energy release, operation malfunction cards, logbooks, coordination meetings, duty-on-call and shift-planning. This paper will summarize the organizational aspects of W7-X technical operation as performed in the first three phases. It will also provide an outlook on the upcoming OP2 (actively cooled divertor) with the requirements for technical operation regarding commissioning and operation towards steady state plasma operation.

组织 Wendelstein 7-X 设备操作


摘要 超导仿星器 Wendelstein 7-X（Bosch 等人，2017）于 2015 年 10 月在格赖夫斯瓦尔德的马克斯普朗克等离子体物理研究所开始其第一个运行阶段，目的是验证仿星器磁约束概念是一个聚变发电厂的可行选择，即显示与托卡马克相当的约束并在稳态运行下运行。 2015年至2018年间，W7-X仿星器的前三个实验活动（运行阶段）OP1.1、OP1.2a和OP1.2b已成功完成。大约 13 个月的运行时间已经积累起来，已经展示了 W7-X 在实现项目设定的物理和技术目标方面令人印象深刻的能力和可靠性。设备操作 (DO) 工作组实施了组织结构和工作流程，以确保 W7-X 设备安全可靠的操作。 DO 负责规划和执行 W7-X 设备的调试和操作。操作计划基于物理规划，该规划是考虑到 W7-X 的技术限制而选择的各个物理建议。操作计划在首席物理学家和设备操作团队 (DOT) 之间进行迭代。 “technischer Leiter vom Dienst”（TLvD 或负责工程师）在 DOT 中发挥着核心作用，负责协调和监督 W7-X 的技术操作。为了确保 W7-X 安全可靠的运行，已经实施和改进了多项程序。这涉及调试模板、清单、程序等。等离子加热能量释放、操作故障卡、日志、协调会议、值班和轮班计划。 本文将总结前三个阶段执行的 W7-X 技术操作的组织方面。它还将对即将推出的 OP2（主动冷却偏滤器）进行展望，并提供有关稳态等离子体操作的调试和操作的技术操作要求。
