Спектроскопические исследования направленных движений плазмы в токовых слоях

The paper is concerned with the studies of the plasma flows evolution in current sheets. The measurements have been carried out in 3D magnetic configurations for the first time. The energy of thermal and directed plasma motions and the plasma density have been determined in the different regions of the sheet. The effect of the longitudinal magnetic field on the plasma heating and acceleration has been examined.
