Determination of Average Ion Temperature of the TVD Tokamak by a Simple Charge Exchange Analyzer Detector

Abstract

In this paper the average ion temperature of the TVD tokamak plasma is determined by a low cost charge exchange analyzer. When the neutral beam energy was equal to 3 keV, the stripping efficiency was 0.065. Estimated average ion temperatures for cold and hot regions of the plasma were 100 and 650 eV, respectively. Unlike the cold region of the plasma in which ion temperature was not related to the time, ion temperature in the hot region was maximum when the plasma current reached its maximum value.Keywords Tokamak Á Total detection efficiency Á Average ion temperature Á Flux of neutral atoms Á Hot and cold region of the plasma
