Essay

The dissertation solves the scientific problem of creating the physical basis of designing, developing, and optimizing plasmodynamic systems of medium energies of a wide range of applications and experimentally demonstrates the possibilities of their application in various branches of modern science and technology. For this purpose, the fundamental physical processes and phenomena occurring in such systems were investigated in order to create a scientific basis for their effective use in the development and optimization of the latest plasma-dynamic devices based on the fundamental plasma-optical principles of magnetic isolation of electrons and equipotentialization of magnetic field lines. The physical mechanisms and features of the processes that occur in plasma-dynamic plasma-optical systems with a space electric charge in the presence of crossed electric and magnetic fields in low vacuum conditions and affect the possibilities of their use in modern scientific experiments and ion-plasma vacuum technologies, in particular, nanotechnologies are investigated.
