Abstract

The magnetoplasma interferometer with pulsed magnetic field source and its measurement accuracy are described. The total accuracy of concentration and mobility measurements free charge carriers depends on oscillations amplitudes and magnetic induction relative errors in general. Also it was determined that magnetoplasma beam spread is influenced on mobility accuracy and correction coefficients should be introduced to mobility formula. Magnetoplasma interferometer with pulsed magnetic field source up to 20T provides non-contact measurements of concentration in (1020 to 1024) m-3 range and mobility in (0,5 to 100) m² V-1s-1 range respectively. Relative error does not exceed 10 % for concentration and 20 % for mobility.
