Návrh nového optického systému pro měření viditelného záření plazmatu na tokamaku COMPASS

Abstract

The paper outlines main parameters and characteristics of the currently designed multichannel optical system for visible plasma radiation measurements on the COMPASS tokamak. It based on registration of visible light in large observation angle (~70-80º) for 35 lines of sights by means of detectors (photodiode or photomultiplier array) and spectrometer. System has resolution about 1cm in vertical direction. The aim of the introduced system is to get information about parameters of tokamak plasma (impurity content and their distribution) and fast processes, which take place in it
