Study Cherenkov radiation by production of positrons and its annihilation in dense plasma focus

Results in Physics, 2019
The purpose of the current study was to evaluate the production of positrons through natNe2D4He18F, nuclear reactions and its possible Cherenkov radiation (CR) before annihilating in the hot and dense plasma medium (pinch) of a Mather type dense plasma ...

Modeling the energy thermalization during the formation of Z-pinch dynamic hohlraums

AIP Advances, 2018
The formation of Z-pinch dynamic hohlraums (ZPDHs) can be regarded as a two-phase process consisting of the energy thermalization and the shock propagation.

Estimation of plasma parameters of X-pinch with time-resolved x-ray spectroscopy

Matter and Radiation at Extremes, 2023
We estimate the parameters of a Cu plasma generated by an X-pinch by comparing experimentally measured x-rays with synthetic data. A filtered absolute extreme ultraviolet diode array is used to measure time-resolved x-ray spectra with a spectral ...

Formation of dense, electromagnetically accelerated plasma for laboratory astrophysics

EPJ Web of Conferences, 2013
We proposed tapered pinch discharge as a measure to conduct laboratory astrophysics experiments. Basic behaviors of the plasma have been characterized using a prototype device. Results show that the plasma flux and velocity depend on initial gas density,

Inference of X-Ray Emission From a Plasma Focus Discharge: Comparison Between Characteristic Parameters and Neural Network Analyses

IEEE Access, 2020
Pulsed plasma discharges, such as the plasma focus, are a source of pulsed X rays, therefore it is desirable to understand the relationship between this fast transient phenomena and the electrical variables of the discharge.
