Vortex Plasmoids Created by High-Frequency
Discharges
A.I. Klimov
Abstract This experimental work is a continuation of the well-known work
on microwave (MW) plasmoid physics carried out by the Nobel prize winner,
P. L. Kapitsa. It is devoted to high-frequency (HF) plasmoid creation in low-
temperature plasma, which is of interest from the point of view of ball lightning (BL)
physics and the creation of artificial ball lightning. New experimental results on HF
plasmoid generation in swirl flows are presented and analyzed. A good correlation
is shown between Kapitsa's results and the new experimental results.

Introduction
There are many reports on ball lightning (BL) creation in the atmosphere during
thunderstorms and without them (Barry 1980 ;Avaramenkoetal. 1994 ; Grigorjev
2006 ; Bychkov et al. 2010 ). Creation of BL and artificial ball lightning from the
plasma vortex, created by either a lightning stroke or high power-electric jets, has
been described in a number of works and is discussed by Bychkov et al. ( 2010 ).
Thus, this work is the continuation of the work of Bychkov et al. ( 2010 )devoted
directly to BL investigations, but it is connected with experiments with discharge
types, which have not obtained sufficient elucidation in the review literature until
now. Well-known works on microwave plasmoids created by Japanese scientists
headed by Y.-H. Ohtsuki and M. Ofuruton were discussed by Bychkov et al. ( 2010 ),
so we do not address their works here.
