FTU collective scattering diagnostics : Scattering geometries, expected performances, antenna decoupling and detection requirements
Collective Thomson Scattering (CTS) has been identified as a useful tool to measure the velocity distribution function of plasma ions. The present report contains a proposal for an experimental programme on the CTS for FTU where a 140 GHz gyrotron is used as main radiation source. The following areas are examined: (i) the concrete problems of the geometries of interest and feasible on FTU; (ii) the signal to noise ratio obtainable for these geometries; (iii) the required decoupling of the collecting and receiving antennae and the detection system.
