Abstract
The effective plasma charge Zeff (proportional to plasma impurity ratio) is of prime importance for controlled fusion by magnetic confinement because it is involved for plasma ignition. From bremsstrahlung radiation theory in the visible part of the spectrum it is shown how effective charge in the plasma is deduced. A validity criterion is established from experiments (radiation at {lambda} = 5235 A) to obtain Zeff profile and error estimation. This profile allows the calculation of resistivity profiles from different theories which are compared to a magnetohydrodynamic code. Calculation time is reduced by a fast analysis method from global parameters given time evolution of Zeff. This last measurement is essentially used for interpretation of experimental results of the Tore Supra physical program.
