Abstract

The detection system designed for the proof-of-principle collective Thomson scattering (CTS) experiments using a 140 GHz gyrotron as a source of probing radiation has been discussed. The system is aimed at ion temperature measurements in a moderate size fusion installations W7-AS stellarator (Garching, Germany) and FTU tokamak (Frascati, Italy) as a first step in CTS experiments using gyrotrons with the prospects of its further upgrading for alpha-particle diagnostics. It is capable of ion temperature measurements for a wide range of plasma parameters (H plasma, D plasma, density range from a few times 10¹³ cm^-3 to 2×10¹⁴ cm^-3, ion temperatures from few hundred eV to a few keV) in various scattering geometries with the scattering angles from 60° to 180°
