Abstract

The Frascati Tokamak Upgrade (FTU) Thomson scattering system is used to measure electron temperature and density spatial profiles along the vertical torus diameter. The Nd:YLF laser source delivers a burst of 10 pulses at a wavelength of 1053 nm. The scattered light is analysed by compact 5-channel interference filter chromators, and the absolute calibration for the electron density measurements is carried out by Raman scattering on hydrogen and deuterium. Scattering data with the interferometer for the density measurement is in agreement with ECE data for the electron temperature.
