Abstract. The paper presents first results of investigations on processes take place in expander of mirror trap where subfusion plasma is confined. It is shown that plasma parameters remain constant at magnetic field expansion ratio decreasing down to K = 30. Potential drop in Debye layer near the end plate for expansion ratios K > 30 appeared to be much lower than electron temperature in the center of the mirror as well as characteristic energy of electrons trapped in the expander region.

“…Researches on the Gas Dynamic Trap (GDT) device at the Budker Institute of Nuclear Physics demonstrated the possibility to overcome these three deficiencies. Stable high energy density plasma can be confined with simple circular magnets [1,2], micro-instabilities can be tamed [3], and electron temperatures reaching a keV have been measured [4,5]. These three accomplishments provide a basis to reconsider the mirror concept as a neutron source for materials development, nuclear fuel production, and fusion energy production.…”

Abstract. The paper includes a brief overview of previous researches on the stabilization of MHD instabilities, study of micro-instabilities, and demonstration a tangible increase of the electron temperature with application of auxiliary ECR heating. A review of the results of recent researches related to application of microwave radiation for plasma generation, and plasma heating in the GDT device is presented. The paper summarizes also recent results of researches that oriented on study of expander physics.

“…Sheared rotation is the most common way of stabilizing a rotating plasma [29,30]. On the other hand, the plasma may be stabilized by other effects like the large orbits of heavy particles or by escaping particles, or it may be possible to use newly proposed stabilization methods [31,32].…”

Plasma Mass Filters For Nuclear Waste Reprocessing

Practical disposal of nuclear waste requires high-throughput separation techniques. The most dangerous part of nuclear waste is the fission product, which contains the most active and mobile radioisotopes and produces most of the heat. We suggest that the fission products could be separated as a group from nuclear waste using plasma mass filters. Plasmabased processes are well suited to separating nuclear waste, because mass rather than chemical properties are used for separation. A single plasma stage can replace several stages of chemical separation, producing separate streams of bulk elements, fission products, and actinoids. The plasma mass filters may have lower cost and produce less auxiliary waste than chemical processing plants. Three rotating plasma configurations are considered that act as mass filters: the plasma centrifuge, the Ohkawa filter, and the asymmetric centrifugal trap.
