Knowledge of the energy spectrum of fast ions in magnetically confined fusion plasmas is important and fundamental for achieving fusion energy production. Collective Thomson scattering (CTS) of high-power electromagnetic radiation is one of the most promising diagnostic methods for measuring the energy spectrum of confined fast ions. A CTS diagnostic has been implemented on the TEXTOR tokamak for the study of fast ions. It uses a 400 kW, 110 GHz gyrotron source as the probe and a high-resolution heterodyne radiometer as the receiver. Details of the system are given in this article. First results from the diagnostic show that scattered radiation has been detected.
