Digital Polychromator

 

General description Spectrum analyzing system for Thomson scattering (TS) signals registration and processing (hereinafter referred to as “system ”) is intended for laboratory plasma investigation by the Thomson scattering method in order to register local values of electrons temperature and density in plasma with detailed temporal and spatial resolution, as well as for recording, storing and processing the obtained data.
