Physical conditions of the ball lightning ejection caused by interaction of electrical discharge with metal and polymer

Physical conditions of formation of the ball lightning with high energy density considered as condensate of heavily excited atoms have been studied. In our approach the ball lightning formation processes is considered as a form of energy-structure self-organi-zation on the base of metastable substance and interchange. We propose different variants of the experimental method to create autonomous formation on the base of the closed capillary discharge allowing to obtain the objects with the life time up to 2s which burn through the foil, explode and can penetrate through the polymer wall without destroying it.

Erosive radially-slotted discharge in sheet current mode

New non-stationary non-contracted form of the erosive radially-slotted discharge as a thin round sheet with the current of the azimuth direction have been discovered, its existence beings stipulated by a radial transport-wave fluxes. Characteristic features of this discharge is self-confinement of the discharge current magnitude, corresponding decrease of the current pulse duration and occurrence of an energy and substance ejection with rather unusual properties. Measurements of kinetics of the discharge current, the plasma radiation intensity and an electrical probe signal, as well as the transmission electron microscope investigations of characteristic aerodisperse aggregates arising the erosive phase, have been carried out. The probe signal duration was about 10 times greater than that of the current; its kinetics was complicated suggesting existence in the slot of two components with fundamentally different properties and states of the substance.
