Coronal loop oscillations and diagnostics with Hinode/EIS [PDF]
, 1974 Context.Standing slow (acoustic) waves commonly observed in hot coronal loops offer a unique opportunity to understand the properties of the coronal plasma. The lack of evidence for similar oscillations in cooler loops is still a puzzle.

Tunability and Losses of Mid-infrared Plasmonics in Heavily Doped Germanium Thin Films [PDF]
, 2016 Heavily-doped semiconductor films are very promising for application in mid-infrared plasmonic devices because the real part of their dielectric function is negative and broadly tunable in this wavelength range. In this work we investigate heavily n-type

Fast High Resolution Echelle Spectroscopy Of A Laboratory Plasma [PDF]
, 2006 An echelle diffraction grating and a multianode photomultiplier tube are paired to construct a high resolution (R=lambda/delta lambda approximate to 2.5x10(4)) spectrograph with fast time response for use from the UV through the visible.

Spectroscopy of laboratory plasmas [PDF]
Space Science Reviews, 1972 AbstractWork under the heading of Laboratory Plasma Spectroscopy may be conveniently separated into three classes depending on the extent to which the interaction of the emitting atoms with their plasma environment is central to the investigation. Zero order, the longest established use of laboratory plasmas in connection with astrophysics, concerns ...

Effect of Plasma on Polyethylene by Positron Lifetime Spectroscopy [PDF]
علوم و تکنولوژی پلیمر, 2022 Hypothesis: The use of plasma is widely used as a method to change polymer surfaces. The use of atmospheric cold plasma has more advantages than other plasma, laser and X-ray methods. This method is simple and it uses inexpensive equipment.

On-Chip Microplasmas for the Detection of Radioactive Cesium Contamination in Seawater
Micromachines, 2017 On-chip microplasmas have previously been used in designing a compact and portable device for identifying pollutants in a water sample. By exciting a liquid sample with a high energy microdischarge and recording the spectral wavelengths emitted, the ...
