The accuracy of a novel Thomson scattering lidar approach for determination of the electron temperature in fusion plasmas is investigated by statistical Monte-Carlo modeling of the measurement process. The approach is based on the unambiguous temperature dependence of the ratio of the signal powers of two wide Thomson scattering spectral regions. It is shown that the accuracy of the novel approach is comparable with those of the center-of-mass wavelength approach we have developed recently and the commonly used fitting approach. Thus, such an approach would be advantageous by the possibility of using essentially simpler hardware consisting of only two receiving spectral channels. [ABSTRACT FROM AUTHOR] |
