    An axial coil accelerator for acceleration of plasma formation having intrinsic magnetic field in the atmosphere is designed. A problem of a round plasma formation in the atmospheric pressure air is solved by electrical wire explo-sion where an initial form of an exploding wire corresponded to a ring. A vortex current into the created plasma ring is inducted by the coil accelerator to generate intrinsic magnetic field of the plasma formation. This process is syn-chronized with reduction in the magnetic coupling between the plasma formation and the accelerator coil during the acceleration.Π ΠΎΠ·Ρ€ΠΎΠ±Π»Π΅Π½Π° Ρ‚Π΅Ρ…Π½Ρ–ΠΊΠ° створСння Ρ‚Π° прискорСння ΠΏΠ»Π°Π·ΠΌΠΎΠ²ΠΎΠ³ΠΎ формування Π· власним ΠΌΠ°Π³Π½Ρ–Ρ‚Π½ΠΈΠΌ ΠΏΠΎΠ»Π΅ΠΌ Π² атмосфСрному сСрСдовищі.

    Laser-generated toroidal helium plasmas

    This dissertation is an experimental study of laser-generated, atmospheric pressure, transient toroidal helium plasmas.The formation mechanism of these toroidal plasmas is identified and an estimate of their main plasma parameters is obtained. Furthermore, preliminary experiments are presented, aimed at heating these plasmas by absorption of microwave radiation, in order to counteract their transient nature.Through a tomographic reconstruction, cross-sectional images of the toroidal plasma are obtained, visualising the fluid flow responsible for the generation of the toroidal structure. The origin of the flow is traced back to the structure of the plasma kernel. The shocks generated by this kernel interact akin to a Mach reflection and generate a low pressure region whose replenishment transforms the plasma into a toroid. Schlieren imaging, complemented with a novel scanning-probe technique, and thermodynamic modelling, as well as deliberately breaking the flow symmetry, confirm the formation mechanism. A high-power, sub-microsecond rise time, pulsed magnetron source has been designed for the microwave heating experiments. Its detailed design and the effect of the microwave pulse on the plasma are discussed.This work is part of a larger study on self-organising knotted magnetic structures in plasma, which may find their application in nuclear fusion and astrophysical research.
