CUMULATION DEVICE OF PLASMA CLOTS Russian patent published in 2019 - IPC H05H1/00 

FIELD: physics.

SUBSTANCE: invention relates to an end-type device intended for cumulation of plasma clots having a long glow period in a free atmosphere. In the disclosed device, a powerful current pulse (duration ≈ 100 ms and current intensity up to 15 kA), generated by induction accumulator of electric energy, is supplied along annular and axial current lead to conducting diaphragm. When electric current flows thereon, it is heated, evaporated and, due to magnetohydrodynamics, in the region of the discharge gap and convective flows, a plasma clot is formed, which passes through the elements of the axial current lead and leaves the region of the discharge gap. Design of the device is characterized by compactness and allows adjusting dimensions of the plasma clot by changing the inner diameter D of the ring current lead from 60 to 150 mm. Ring electrode is made from non-magnetic material, and the axial electrode consists of a set of radially arranged current-conducting wires.

EFFECT: technical result is increase of plasma clot luminescence time in free atmosphere to 2 s.
