High Current Plasma Accelerators: Physics and Applications
Abstract
In this review paper, basic principles of high current plasma accelerators, history and recent state of their investigations in IPP NSC KIPT are briefly described. In such devices an internal magnetic field is created by high current up to several MA in the discharge and it is used for both plasma flow acceleration up to 1000 km/s. Particular attention is paid to the quasi-stationary plasma accelerators (QSPA), where discharge duration exceeds considerable the plasma flight time in acceleration channel. Application of QSPA for plasma-surface interaction studies relevant to thermonuclear reactors, like ITER and DEMO, is discussed. Results on surface modification and improvement of material properties by powerful pulsed plasma processing are described. Potential technological applications for materials treatment are emphasized.
