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.

Opis:
A review of results on the design and operation of the new efficient Dense Plasma Focus device PF-6 of medium size (transportable) having bank energy of ca. 7 kJ and possessing a long lifetime is presented. New data on the interaction of the pulsed fast ion beams and dense plasma streams generated at this apparatus with various materials are given. These results are compared with the analogous information received at the biggest facility PF-1000. It is shown that it is possible to have about the same power flux density (in the range of 105 109 W/cm2) in both devices however in different areas. Doses of soft X-rays produced by the device within the resists for the goals of microlithography and micromachining appear to be several times less that it is with the conventional X-ray tube. In biological application of this device, medium- and hard-energy X-rays are exploited in the field of radioenzymology. It was found that the necessary dose producing activation/inactivation of enzymes can be by several orders of magnitude lower if used at a high-power flux density in comparison with those received with isotope sources. In medicine, short-life isotope production for the goals of the positron emission tomography (medicine diagnostics) is possible by means of the fast ions generated within DPF. All these experiments are discussed in the framework of pulsed radiation physics and chemistry in its perfect sense thereto the criteria are formulated.
