The COMPASS tokamak, originally from Culham laboratory, UKAEA, has been reinstalled at at Institute of Plasma Physics, Prague. Many innovations will be done and new diagnostics have to be constructed. Electron temperature Te and density ne as as key parameters of fusion plasma will be measured directly by the newly designed high spatial resolution incoherent Thomson scattering (TS) system. Several construction options of TS are considered. In this paper these options are discussed from a point of view of data analysis and estimation of background radiation.

Tokamak COMPASS byl z laboratoří v Culhamu, Velká Británie přeinstalován v Ústavu fyziky plazmatu v Praze. Mezi nově projektovanými diagnostikami plazmatu pro tokamak COMPASS je i metoda nekoherentního Thomsonova rozptylu pro přímé měření elektronové teploty a hustoty v plazmatu. Několik možností konstrukce této diagnostiky je v článku diskutováno z hlediska analýzy dat a odhadnuté velikosti záření pozadí z plazmatu.
