Using a one-dimensional kinetic model the dependence of the collector floating potential was predicted as a function of the hot to cool electron density and temperature ratio. To our knowledge we were the first group to include three different electron populations into such a model. The Poisson equation was solved numerically and axial profiles of the moments of the particle distribution function were predicted. All the results of the model and of the numerical solutions are in excellent agreement with the results of the PIC computer simulations.

Removal of hydrogenated carbon deposits in fusion reactors by treatment with plasma represents a promising method. Since the relevant literature does not report about possible modification of stainless steel due to interaction with aggressive plasma, we reported about results of original experiments that show important changes of recombination coefficient due to plasma treatment.
