Azimuthal self-pressed gas discharge with trapped longitudinal magnetic flow

Summary form only given. High-current radiating discharges for optical pumping of gas lasers are usually formed in electrode longitudinal configurations with supplying by means of capacitive storages of energy. In the present report the results of research an original azimuthal discharge, pressed to inner wall of a cylindrical dielectric chamber by pressure of a trapped longitudinal magnetic field are informed. To form the azimuthal discharge a three-winding three-layer solenoid, which simultaneously was an inductive storage of energy was applied. The current supplying of the inductive storage was carried out with the help of a primary capacitive storage with energetic capacity of 60 kJ at charging voltage of 50 kV. An electroexplosive foil opening switch was applied as a current breaker of the inductive storage. At the moment of a maximum charging current a near-wall plasma winding was created by excitation of a longitudinal creeping discharge. The electrical explosion of an aluminum foil in this moment resulted in trapping of longitudinal magnetic field by azimuthal plasma current in volume of the discharge chamber with a diameter of 10 cm and dissipating of external magnetic field energy. In the further the supporting of azimuthal current was carried out at the expense of trapped magnetic field energy. The maximum brightness temperature of the plasma layer reached 4 eV. In the report the results of research of dynamics and radiative properties of a plasma layer are adduced.
