“…The criterion for the possibility of implementing this is a comparative analysis of the physical compatibility of the complex parameters of the two objects of study. Four parameters are considered in comparison (table 1): the physical mechanism of the process, the composition of the working substance, the presence of a neutron output, parametric characteristics of the plasma generated during the process [1][2][3].…”

Based on theoretical ideas about different plasma processes in Nature and Space, for example of Solar flares, a conceptual model approach is proposed based on the analogy of the flash flow with processes in an electrical circuit. Quite close in a number of parameters to the flashes are the processes of evolution of plasma objects in the "Plasma focus" setup. Based on the physical similarity of processes of this kind, patterns have been studied that make it possible to trace the change in plasma temperature depending on changes in the operating parameters of the setup. The parameters of the model corresponding to the maximum approximation to the conditions of the flash process are revealed. A program has been developed, calculations and analysis of the dependence of the plasma temperature on the parameters of the setup have been carried out: gas mass, velocity of incoming particles, load resistance in the plasma focus. It is shown that the physical model of a solar flare "Electric Circuit" can be implemented on the basis of an operating plasma focus setup, taking into account the scaling of processes.

“…The CS velocity is estimated by dividing the distance (2 cm) by the difference in the time between the two peaks (detected by the two probes). 23,29,34) The CS velocity is estimated from the two magnetic probes signals which are shown in Fig. 6 at the operating conditions of 0.5 Torr helium gas pressure and 5 kV charging voltage.…”

This paper presents preliminary results for a new design of a pulsed linear plasma device that generates electromagnetic plasma propulsion. The current sheath dynamics and the plasma propulsion along an extension tube have been studied. Breakdown of helium gas occurs between coaxial electrodes when applying a high-voltage pulse. This paper presents measurements with a number of probes, as well as camera images of the plasma propagation. A plasma is ejected and fills a 40 cm length extension tube. Additionally, the measurements show that the length of the propelled plasma column and its intensity inside the expansion tube is increased by increasing the charging voltage, while the plasma propulsion current is decreased along the extension tube. It is noted that a lower critical time; 4.7 μs, is needed to ionize the gas and form the plasma current sheath.

The dynamic characteristics of neutron emission and anisotropy depending on the gas pressure in a thermonuclear installation of a plasma focus were studied. Two plastic scintillation photoelectron multipliers and two activation detectors were used for diagnostic measurements. Experimental results showed that the values of neutron emission fluctuate in the range 5,5 106-5,11 107 n/imp also were explained two mechanisms of neutron production and anisotropy in the optimal pressure range.
