Design criteria of the bolometer diagnostic for steady-state operation of the W7-X stellarator.
D. Zhang,R. Burhenn,R. Koenig,L. Giannone,P. A. Grodzki,Bernhard Klein,K. Grosser,J. Baldzuhn,K. Ewert,V. Erckmann,M. Hirsch,H. P. Laqua,J. W. Oosterbeek +12 more
TL;DR: An overview of the technical problems encountered during the design work and the solutions to individual problems to meet the special requirements in W7-X, e.g., component thermal protection, detector offset thermal drift suppression, as well as a microwave shielding technique are given.
Journal ArticleDOI
Engineering design for the magnetic diagnostics of Wendelstein 7-X
M. Endler,B. Brucker,V. Bykov,A. Cardella,A. Carls,F. Dobmeier,A. Dudek,Joris Fellinger,J. Geiger,K. Grosser,Olaf Grulke,D. A. Hartmann,Dag Hathiramani,K. Höchel,Martin Köppen,R. Laube,Ulrich Neuner,X.B. Peng,Kian Rahbarnia,K. Rummel,T. Sieber,Stefan Thiel,A. Vorköper,A. Werner,T. Windisch,M. Y. Ye +25 more
TL;DR: The Wendelstein 7-X (W7-X) stellarator as discussed by the authors was designed as a pick-up coil to measure the toroidal plasma current, saddle coils to measure Pfirsch-Schluter currents, and segmented Rogowski coils (poloidal magnetic field probes) to add information on the distribution of the plasma current density.
Journal ArticleDOI
Microwave stray radiation: Measures for steady state diagnostics at Wendelstein 7-X
Dag Hathiramani,Roland Binder,R. Brakel,Torsten Broszat,Bertram Brucker,Antonino Cardella,M. Endler,K. Grosser,M. Hirsch,Heinrich P. Laqua,Stefan Thiel +10 more
TL;DR: In this paper, the main heating system of W7-X will be a 10MW, 140 GHz ECRH, and it is expected that the non-absorbed energy will be up to 1 MW.
Journal ArticleDOI
Startup impurity diagnostics in Wendelstein 7-X stellarator in the first operational phase

TL;DR: In this article, a set of plasma diagnostics is foreseen to obtain key experimental quantities for the neoclassical transport modeling as ion temperature profile, density gradients and impurity concentration.
Journal ArticleDOI
