Influence of Nano-Scale Clusters on Gas Dynamics Parameters of Plasma Jet Created by Capillary Type Discharge

Our experiments show that parameters and flow regimes of plasma jet created by a pulsed discharge in a capillary are essentially determined by nano-scale clusters, the source of which is the ablative substance of the capillary wall. Estimations show that parameters of plasma and clusters can satisfy the conditions of like-charged particles attraction that provides plasma confinement within the jet boundaries and is the reason of properties, more typical to liquid jet, especially: long propagation range, the lack of divergence, shape integrity and stability in the gas flow, long relaxation time after the discharge off.
