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.

This original scientific paper published in a top quality specialized scientific journal presents the rsults of our studies of the potential formation in front of an electron emitting electrode immersed in a two-electron temperature plasma. Such electron distrobutions are characteristical for edge plasmas of fusion devices. We presented the application of two methods that we have developed ourselves for the determination of the correct Bohm criterion for given plasma parameters.

We developed a one-dimensional fluid model, which we then used for the anlysis of the potential formation in front of an electron emitting electrode immersed in a plasma that contains a mono-energetic electron beam with an isotropic velocity distribution. Our model explains triple floating potentials of electron emitting electrodes, which were observed experimentally, but so far the explanation has been only qualitative. Our model offers a quantitative explanation taking into account space charge effects of emitted electrons.

This original scientific paper was published in a top quality journal specialized in surface and coatings. Results of systematic research on removal of hydrogenated carbon from deposits formed in advanced fusion reactors with divertors made from tungsten and CFC composite are presented. The experiment was performed at European solar centre Font Romeu. These results clearly show the applicability of our original technology for removal of deposits in future fusion reactor ITER.
