TL;DR: In this article, the first in situ cleaning using radiofrequency (RF) plasma was conducted in EAST tokamak with a mock-up plate of ITER edge Thomson Scattering (ETS) with five inserted mirrors.
Journal ArticleDOI

TL;DR: The ITER core charge exchange recombination spectroscopy (core CXRS) diagnostic system as discussed by the authors is designed to provide experimental access to various measurement quantities in the core plasma such as ion densities, temperatures and velocities.
Journal ArticleDOI
Development of design options for the port plug components of the ITER core CXRS diagnostic
Yu. Krasikov,T. Baross,Wolfgang Biel,Andrey Litnovsky,N. C. Hawkes,G. Kiss,J.F.F. Klinkhamer,J.F. Koning,A. Krimmer,Olaf Neubauer,Anatoly Panin +10 more
TL;DR: In this article, the authors present component concepts developed for the ITER core charge exchange recombination spectroscopy (cCXRS) based on the reference design option, which includes an outer shell, carrying a blanket shield module and a shielding cassette.
Journal ArticleDOI
Passive protection of the ITER diagnostic mirrors
TL;DR: In this article, a conservative engineering model of the impurity deposition on the diagnostic mirrors is proposed to analyze numerically the effect of protecting structures (ducts) with and without baffles in the conditions of the ITER main chamber.
Journal ArticleDOI
In situ measurements of the spectral reflectance of metallic mirrors at the Hα line in a low density Ar-H plasma.
S. Dickheuer,Oleksandr Marchuk,Christian Brandt,A. Pospieszczyk,A. Goriaev,Mykola Ialovega,B. Göths,Yuri Krasikov,A. Krimmer,Philippe Mertens,Arkadi Kreter +10 more
TL;DR: A new technique based on the ratio of the red- and blue-shifted emission signals of the reflected hydrogen atoms which enables the in situ measurement of the spectral reflectance of metallic mirrors in low-density Ar-H or Ar-D plasmas is proposed.
