The spatial profile of neutral hydrogen temperatures in Aditya-U tokamak plasma has been estimated from the spatial profile of the Hα spectral emissions measured using a high-resolution multi-track spectrometer. having a spectral resolution of 0. 023 nm at a 50 μm entrance slit width. The neutral temperature estimation from the Doppler broadened spectral line was carried out... https://www.kingarte.com/product-category/cutlerykitchen-barflatware-knives-2/
