  • Electron density and temperature radial profiles in the peripheral plasma of Tore Supra using a laser blow-off lithium and fluorine atomic beam

Abstract

A laser blow-off atomic beam has been used on the Tore Supra (TS) tokamak to measure the electron density, n(e), and temperature, T(e), profiles in the plasma periphery. Although the diagnostic set-up is far from ideal, the n(e) profiles (from lithium injection) agree with those measured by the other diagnostics. TS being an all-carbon tokamak, we have attempted to measure T(e) by injecting fluorine. The resulting T(e) profiles are systematically higher (by a factor of 2) than those measured by a reciprocating Langmuir probe, presumably because of the poor knowledge of the fluorine relevant atomic rates.
