Title: Effect of a non-Maxwellian electron distribution on the ion charge state and the accuracy of impurity diagnostics in a plasma with ohmic heating

Abstract

Calculations are reported which demonstrate the importance of taking into account the deviation from a Maxwellian electron distribution in impurity diagnostics in tokamaks. At the field levels in existing tokamaks, the ion charge distribution shifts toward higher charges. A different ion may become the ''most representative'' ion.
