Resumen
In this work we show results of measurements of the electron density ne and temperature Te by using small-angle Thomson scattering in a theta-pinch plasma. The method of measurement and analysis developed here is based on integration of only two ranges of the scattering profile. This method simplifies the experimental set up, because it needs only two detectors for simultaneous determination of ne and Te, instead of the commonly 5-7 detectors used in 90° experiments. The results obtained for low-angle scattering are compared with the measurements at 90° using single pass and multipass under the same plasma conditions. 256 01/02/15 437 441 Berni, L.A., Campos, D.O., Machida, M., Moshkalyov, S.A., Lebedev, S.V., Molecular Rayleigh scattering as calibration method for Thomson scattering experiments (1996) Brazilian Journal of Physics, 26 (4), p. 755 Campos, D.O., Machida, M., Berni, L.A., Moshkalyov, S.A., Lebedev, S.V., The feasibility study of a low-angle Thomson scattering for determination of plasma electron density and temperature (1995) 3o, Encontro Brasileiro de Física dos Plasmas - Fifth Brazilian Plasma Astrophysics Workshop, , Águas de Lindóida, SP, 4-6 December 1995 Campos, D.O., Machida, M., Berni, L.A., Kantor, M., Moshkalyov, S.A., Lebedev, S.V., Experimental study of conventional and multipass Thomson scattering diagnostics (1996) Japanese Journal of Applied Physics, 35 (12 A), p. 6273 Campos, D.O., Machida, M., Berni, L.A., Kantor, M., Moshkalyov, S.A., Lebedev, S.V., The application of a multipass system for Thomson scattering diagnostics in magnetically confined plasmas (1996) Brazilian Journal of Physics, 26 (4), p. 742 Sheffield, J., (1975) Plasma Scattering of Electromagnetic Radiation, , Academic Press, New York
