Organized Structeres, Magnetic Reconnections and Acceleration of Fast Beams in Plasma-Focus Fusion Plasma

Fusion plasmas produced in tokamaks, inertial-fusion experiments with powerful lasers, and z-pinch discharges, deal with similar questions concerning the generation of high energy beams of charge particles, similar to those emitted from plasmas in Universe1-3. In all cases, a fast release of magnetic energy during magnetic reconnections of various organized structures is often considered. Dense plasmas, which are produced in plasma-focus discharges, have some advantages in solving this problem, since they have very convenient parameters for complementary diagnostics with relative simple temporal-, spatial- and spectral-resolution. The described experimental research on DD fusion reactions was performed at the current intensity of about 1 MA and the total neutron yield of about 1010 per shot. A multi-frame interferometry system, scintillation detectors, as well as X -ray and corpuscular diagnostic equipment - made it possible to study the evolution of toroidal- and plasmoidal-structures, which were formed by closed currents with poloidal and toroidal components in filamentary forms. The production of hard X -rays and fusion neutrons correlated with the formation and decay of plasmoids4. The gained knowledge about evolution of the ordered structures, transformations of currents and magnetic fields - can be an inspiration for researchers of the tokamak- and laser-fusion as well as for astrophysicists community.
