Wideband spectral emission measurements from laser-produced plasma EUV/SXR source based on a double gas puff target [PDF]

Metrology and Measurement Systems, 2021
We present spectral emission characteristics from laser-plasma EUV/SXR sources produced by irradiation of < 1 J energy laser pulse on eleven different double stream gas puff targets, with most intense electronic transitions identified in the spectral ...

Potential of Clay-Based Geomaterials for Passive Treatment of Brackish and Saline Waters [PDF]

BIO Web of Conferences
The increasing salinity and water scarcity of water resources are major problems in semi-arid or arid regions. This study examines the possibilities of a hybrid geomaterial based on clay to treat passively water bodies that are brackish or saline made ...

An in-depth study of the pre-polar candidate WX Leonis Minoris [PDF]

, 2006
Optical photometry, spectroscopy, and XMM-Newton ultraviolet and X-ray observations with full phase coverage are used for an in-depth study of WXLMi, a system formerly termed a low-accretion rate polar.

Inactivation of Escherichia coli by atmospheric pressure plasma jet in water

Journal of Water and Health, 2022
The main aim of this work is inactivation of Escherichia coli in water using a laboratory-scale radio-frequency atmospheric pressure Argon plasma jet. This bacterium is widely present in the environment, especially in drinking water, and its pathogenic ...

Absorption Imaging and Spectroscopy of Ultracold Neutral Plasmas [PDF]

, 2004
Absorption imaging and spectroscopy can probe the dynamics of an ultracold neutral plasma during the first few microseconds after its creation. Quantitative analysis of the data, however, is complicated by the inhomogeneous density distribution ...

Use of the Plasma Spectrum RMS Signal for Arc-Welding Diagnostics

Sensors, 2009
A new spectroscopic parameter is used in this paper for on-line arc-welding quality monitoring. Plasma spectroscopy applied to welding diagnostics has typically relied on the estimation of the plasma electronic temperature, as there is a known ...

Experimental Realization of an Exact Solution to the Vlasov Equations for an Expanding Plasma [PDF]

, 2007
We study the expansion of ultracold neutral plasmas in the regime in which inelastic collisions are negligible. The plasma expands due to the thermal pressure of the electrons, and for an initial spherically symmetric Gaussian density profle, the ...

Second order reflection from crystals used in soft X-ray spectroscopy

Nukleonika, 2015
In this note the ratio of the second to the first order reflection is determined for the KAP and PbSt crystals, for wavelengths corresponding to the Al K-line emission. The source of the radiation was a low-voltage stabilized X-ray tube.

Review of Rydberg Spectral Line Formation in Plasmas

Atoms, 2023
The present review is dedicated to the problem of an array of transitions between highly-excited atomic levels. Hydrogen atoms and hydrogen-like ions in plasmas are considered here. The presented methods focus on calculation of spectral line shapes. Fast
