Abstract Fusion energy research has in the past 40 years focused primarily on tokamak concept, but recent advances plasma theory and computational power have led to renewed interest stellarators. The largest most sophisticated stellarator world, Wendelstein 7-X (W7-X), just started operation, with aim show that earlier weaknesses of this concept been addressed successfully, intrinsic advantages persist, also at parameters approaching those a future fusion plant. Here we first physics...
The next step in the Wendelstein stellarator line is large superconducting device 7-X, currently under construction Greifswald, Germany. Steady-state operation an intrinsic feature of stellarators, and one key element 7-X mission to demonstrate steady-state plasma conditions relevant for a fusion power plant. device, on hand, requires implementation special technologies, giving rise technical challenges during design, fabrication assembly such device. On other also physics development at...
Wendelstein 7-X was built for the research on steady state operation of stellarators. This sets high requirements control and data acquisition (CoDaC) system, with archive database as one its main components. W7-X Archive is storage all operational scientific data. It stores raw well processed provides a single wide range components types. The WEB API unified access to by using web service technologies. based REST architecture style, HTTP application protocol: represented signal resource,...
Wendelstein 7-X is intended to demonstrate steady state high performance plasma operation and explore the physics basis of Helias reactor concept. From there, W7-X CoDaC concepts aim for stabilization at favorite points largely or even fully documented experiments achieving efficiently scientific results. Several are being employed that not common fusion research so far. The control system based on segments consisting parameters transition conditions other segments. data acquisition aims...
The Wendelstein 7-X steady state plasma control and data acquisition system has been successfully commissioned well established to investigate the startup run first complex physics programs during initial operation phase of W7-X. main components W7-X a set operational diagnostics have integrated into CoDaC system. various different requests from experimenters could be satisfied using tools interfaces − demonstrating their qualification for continuous operation. This paper summarizes workflow...
Wendelstein 7-X (W7-X) is a superconducting stellarator having undergone the first experimental campaign after its construction. It capable of steady state magnetic field operation. After an upgrade to cope with permanent heat loads several Megawatts, W7-X will be able run discharges, too. The control system demonstrated support all types experiments compatible operation, i.e. short plasma discharges and sequences arbitrary time intervals. contribution describes basic concepts system....
