Divertor interferometer diagnostic for ITER
In the harsh environment of the divertor region in ITER, plasmas spanning a huge density range from 1019 to 1022 m−3 are anticipated making measurement of the electron density particularly challenging. For any reasonable wavelength choice, the total phase measured by a conventional two-color interferometer system is always 2 and therefore subject to fringe counting errors. This problem can be r...
متن کاملExploitation of Avalanche Photodiodes for Thomson Scattering Diagnostics in Tokamaks
The COMPASS tokamak, originally from UKAEA, Culham laboratory, U.K., will be reinstalled at Institute of Plasma Physics, Prague. The scientific programme is focused mainly on the investigation of the edge plasma region with high temperature and density gradients called pedestal. Many innovations will be done and new diagnostics have to be constructed. One of the key diagnostics is an incoherent...
متن کاملDesign of Filters for COMPASS Thomson Scattering Diagnostics
Reinstalled tokamak COMPASS, originally from Culham Science Centre, is now operating at the Institute of Plasma Physics, Prague and many new optical diagnostics are being developed [Sestak et al, 2009]. For measurement of electron temperature and density profiles, high resolution incoherent Thomson scattering spectroscopy based on Nd:YAG laser and avalanche photodiodes is under development now....
متن کاملUpgrade of the infrared camera diagnostics for the JET ITER-like wall divertor.
For the new ITER-like wall at JET, two new infrared diagnostics (KL9B, KL3B) have been installed. These diagnostics can operate between 3.5 and 5 μm and up to sampling frequencies of ∼20 kHz. KL9B and KL3B image the horizontal and vertical tiles of the divertor. The divertor tiles are tungsten coated carbon fiber composite except the central tile ...
متن کاملDesign study of the divertor Thomson scattering system for JT-60SA
Feasibility study of the divertor Thomson scattering measurement system for JT-60SA is carried out. A case study of different optical configurations reveals that both laser transmission optics and collection optical system are to be embedded in the lower narrow port plug. From the perspective of the laser induced damage threshold, the size and the material for the laser transmission mirror are ...
