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 ...

Laboratory simulations of astrophysical jets and solar coronal loops: new results [PDF]
, 2010 An experimental program underway at Caltech has produced plasmas where the shape is neither fixed by the vacuum chamber nor fixed by an external coil set, but instead is determined by self-organization.

High resolution charge-exchange spectroscopic measurements of aluminum impurity ions in a high temperature plasma [PDF]
, 2012 Charge-exchange recombination spectroscopy, which is generally used to measure low-Z impurities in fusion devices, has been used for measuring Al+11 and Al+13 impurities in the Madison Symmetric Torus reversed field pinch.

Impurity and Trace Tritium Transport in Tokamak Edge Turbulence [PDF]
, 2004 The turbulent transport of impurity or minority species, as for example Tritium, is investigated in drift-Alfv\'en edge turbulence. The full effects of perpendicular and parallel convection are kept for the impurity species. The impurity density develops

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,
