Opis:
The report describes some of the results obtained in an experimental study of the impact of a powerful plasma stream and a fast ion beam generated in a PF-1000 device on different materials perspective for the use in radiation loaded parts of pulsed plasma installations. Investigations were done during and after the interaction processes. It is shown that in case of irradiation of samples only by high power flux density plasma streams the effect of detachment still preserved. At the same time a low power flux density high-energy ion beam plays an important role in the process of saturation of the irradiated material by hydrogen.

Opis:
The results of experimental investigations of powerful hydrogen plasma jets and fast ion beams interaction with various materials (austenitic chromium-manganese steels, pure vanadium, tungsten, graphite, copper, and their alloys: Cu-4 mass% Ni and Cu-10 mass% Ga) are presented. The materials were placed on the discharge axis of the PF-1000 device and irradiated with fluxes of fast ions (of energy in the range from tens keV up to several MeV) and with plasma streams (of power flux density q~(108 109) W/cm2). It was found that the fast ions and plasma streams caused different damages to the aforementioned materials. A diverse character of the damages to the individual investigated material was revealed. Some peculiarities of the process as well as the correlation between the surface density of the "macroscopic" structural defects (blisters and craters) and the fluence of the fast ions implanted in the specimen are discussed.

Opis:
A review of the results received in the course of fulfillment of the International Atomic Energy Agency Co-ordinated Research Project “Dense Magnetized Plasma” for the last 3 years is presented. Niche of the plasma type within the plasma physics field is outlined. Efforts of the CRP participants concentrated on design and operation of new Dense Magnetized Plasma devices are described. All of them designed for plasma heating and for other applications mainly based on the interaction of radiations generated by the devices with different objects. Materials exploitable, diagnostics of the interaction processes, as well as analytical equipment used by the participants to process the irradiated targets are described. Works developed in the frame of the CRP are covered thermonuclear fusion applications, fundamental plasma physics and material science issues, medicine, biology, and some other spheres. New data on the interaction of the radiations generated in this apparatus with various materials are given. E.g. it was found that the necessary dose producing activation/inactivation of enzymes can be much lower if used at a high-power flux density in comparison with those received with classical sources. All these experiments are discussed in the framework of pulsed radiation chemistry in its perfect sense thereto the criteria are formulated. New foreseen applications of DMP devices mainly based on neutron radiation are proposed and discussed.
