Several models of quasi-stationary high-current plasma accelerators of a new generation were developed in the Laboratory of Plasma Accelerators Physics. These plasmadynamic systems operate in the ion current transfer mode and provide the ion-drift acceleration of magnetized plasma. Our installations generate high-energy compression plasma flows of specified composition and on a set of parameters (plasma velocity – 50 ÷ 200 km/s, temperature and concentration of charged particles – (40 ÷ 200)•103 K and 1016 ÷ 1018 cm-3 accordingly, discharge duration – 100 ÷ 500 microseconds) surpass all other available types of plasma accelerators.
