Fast Ion Collective Thomson Scattering Diagnostic for ITER - Progress of Design

摘要: In the era of high power and burning plasma fusion experiments with significant populations fast particles, diagnosis ion dynamics becomes an important topic. ITER, ions due to ICRH NBI, as well born alphas will carry a fraction free energy plasma. This may affect instabilities transport in A key candidate for diagnosing confined ITER is technique collective Thomson scattering (CTS). CTS system probing frequency 60 GHz has been proposed ITER. Based on diagnostic experience from particularly TEXTOR ASDEX Upgrade, work now progressing towards final design The biggest challenge HFS receiver located restricted space behind blanket modules. Calculations series mock‐up measurements have brought four mirror quasi‐optical solution. development present be presented.
