Abstract:
This paper presents an experimental demonstration to determine electron temperature (Te) with unknown spectral sensitivity (transmissivity) in a Thomson scattering system. In this method, a double-pass scattering configuration is used and the scattered lights from each pass (with different scattering angles) are measured separately. Te can be determined from the ratio of the signal intensities without knowing a real chromatic dependence in the sensitivity. Note that the wavelength range for each spectral channel must be known. This method was applied to the TST-2 Thomson scattering system. As a result, Te measured from the ratio (Te,r) and Te measured from a standard method (Te,s) showed a good agreement with 〈|Te,r − Te,s|/Te,s〉 = 7.3%.
