Unraveling the excitation mechanisms of highly oblique lower band chorus waves

Geophysical Research Letters, 2016
Excitation mechanisms of highly oblique, quasi‐electrostatic lower band chorus waves are investigated using Van Allen Probes observations near the equator of the Earth's magnetosphere. Linear growth rates are evaluated based on in situ, measured electron

Evolution and characteristics of global pc5 ULF waves during a high solar wind speed interval [PDF]

, 2005
We present an interval of extremely long-lasting narrow-band Pc5 pulsations during the recovery phase of a large geomagnetic storm. These pulsations occurred continuously for many hours and were observed throughout the magnetosphere and in the dusk ...

Ion-Beam-Excited, Electrostatic, Ion Cyclotron Instability

, 1977
The stability limits of the ion‐beam‐excited, electrostatic, ion cyclotron instability were investigated in a Q‐machine plasma where the electrons could be heated by microwaves. In agreement with theory, the beam energy necessary for excitation decreased

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

High Power Laser-Grating Interaction

, 2011
A system which presents a periodic optical structure is usually referred to as a photonic structure, for its light manipulation capabilities. The most simple one dimensional photonic structure that can be made of metallic material is a diffraction ...

Continuous batch synthesis with atmospheric-pressure microwave plasmas

iScience
Summary: Plasmas under atmospheric pressure offer a high-temperature environment for material synthesis, but electrode ablation compromises purity. Here, we introduce an atmospheric-pressure microwave plasma (AMP) operated without electrodes to overcome ...

Electrostatic Plasma Instabilities Excited by a High-Frequency Electric Field

The Physics of Fluids, 1970
The electrostatic plasma waves excited by a uniform, alternating electric field of arbitrary intensity are studied on the basis of the Vlasov equation; their dispersion relation, which involves the determinant of either of two infinite matrices, is derived.
