popup.description1
Experimental studies of accelerators with a plasma opening switch and inductive energy storage are expected to be carried out in order to clarify the physical mechanisms of current switching in a plasma opening switch to stabilize the output parameters of high-current small-sized electron accelerators of direct action. Microplasma oxidation of the materials surfaces is expected to carry out in order to improve the characteristics of materials’ for plasma and accelerator technology. Research of ion separation in a multicomponent plasma rotating in the crossed magnetic and electric fields is supposed to be carried out for simulation of nuclear fuel separation from spent nuclear fuel in a closed nuclear fuel cycle by plasma methods.

The object of the investigation - plasma source of the electroerosion type, made of materials simulating spent nuclear fuel and installed on the DIS-1 magneto-plasma separator. The material is formed by the plasma source, which is deposited on the collector targets. The magnetic field of the plasma source, which ensures the prevention of losses of the formed plasma.
The purpose of the work – modernization of the demonstration and simulation separator DIS-1, by creating a plasma source of the electroerosion type with a breakdown on the surface of the dielectric. Obtaining material in the form of plasma, which consists of electrode substances. Ensuring the formation of metal plasma from materials that are components of fuel elements, in particular Zr. Creation and calculation of a magnetic field in the plasma source area, which will reduce plasma losses and ensure effective distribution of the material to be separated by mass in the magneto-plasma separator.
The main scientific results are as follows:
-for the first time, the plasma source of metal plasma of spent nuclear fuel simulants made of Zr and Ti, as well as a ceramic dielectric in the form of ZrO2, was designed, manufactured and put into operation in order to obtain plasma with the appropriate composition, which should be separated by mass in a magneto-plasma separator;
- for the first time, the trajectory of Zr and Ti motion in crossed electric and magnetic fields was calculated. Where the magnetic field B in the source region was a maximum of 0.12 T, and the electric field varied from 40 to 140 V. The exit points of Zr, which imitates uranium and uranium elements, onto the side surface of the separator, and, accordingly, the locations of the collectors, were determined.
