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.

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.

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.

TL;DR: The CXRS (charge-eXchange Recombination Spectroscopy) diagnostic for the core plasma of ITER will be designed to provide observation of the dedicated diagnostic beam (DNB) over a wide radial range, roughly from a normalised radius r/a = 07 to close to the plasma axis as discussed by the authors.
Diagnostic mirror concept development for use in the complex environment of a fusion reactor
A. Krimmer,Hans-Josef Allelein,U. Samm,Lorenz Singheiser +3 more
- 01 Jan 2017
TL;DR: The fusion reactor mirror design considerations given in the principal design discussion can be used as a basis for other diagnostic systems as well, and basic suitability was shown and critical topics were identified where additional work is necessary.
