On the possibility of accelerating charged particles in the low-pressure acoustoplasma and plasma bunches in the air

In this paper obtained results of two experimental investigations are presented: on the acceleration of electrons in low-pressure acoustoplasma discharge and acceleration of plasma bunch-plasmoids in the air. The first experimental results on the acceleration of electrons in the low-pressure discharge were obtained in 2008. In the current paper an attempt to explain the obtained results by means of wake accelerations of particles in electromagnetic fields without utilization of usual drivers is made. Formerly calculated theoretical data for accelerated particles even in the energy range of 10–100 eV are experimentally confirmed. Experimental investigations on origination and initiating acceleration of plasma bunches in crossed fields in the air were conducted in 2023. In the current paper the obtained first results on acceleration of the originated long-life plasmoids in the air are presented as an announcement of our planned subsequent corresponding investigations. To carry out corresponding experiments a unique experimental setup, as well as appropriate devices and equipment were developed. A new conceptual model of a plasmoid is offered. The realization of this concept opens the possibility of carrying out the experimental investigations of the phenomena of origination of long-life plasmoids in air. During the experimental investigations, any ionizing additives into the discharge were not injected.
