Abstract

A Multichannel Thomson Scattering apparatus is under development for the measurement of the spatial profile of electron temperature and density in the ETA-BETA II Reverse Field Pinch experiment. According to the approach first adopted in TFR, a set of different spectrometers will be used for the measurements at the various spatial positions, and the temperature and density will be deduced by measuring the power scattered in two different, suitably chosen, spectral bands. Each spectrometer uses a plane holographic grating and a F/2.4 achromatic doublet in a Littrow mounting and has a throughput of 2x10 RU-2 cm**2 sr. Four photomultipliers are fitted in each spectrometer so that one instrument can be used for simultaneous measurements at two spatial positions.
