Ion acoustic solitons at the acoustic speed in a warm negative ion plasma with superthermal electrons

AIP Advances, 2023
Using the Sagdeev pseudopotential method, the existence of Korteweg–de Vries (KdV) and non-KdV solitons is investigated in a negative ion plasma comprising adiabatic positive and negative ions and kappa distributed electrons.

Effect of Negative Ion Generation on Complex Plasma Structure Properties

Molecules, 2022
We propose a low-density discharge plasma model that takes into account the impact of oxygen admixture in typical conditions of complex (dusty) plasmas.

Negative ions in the auroral mesosphere during a PCA event around sunset [PDF]

Annales Geophysicae, 1999
This is a study of the negative ion chemistry in the mesosphere above Tromsø using a number of EISCAT observations of high energy proton precipitation events during the last solar maximum, and in particular around sunset on 23 October, 1989.

Negative Ion Formation by the Thermal Surface Ionization of Oxygen-Bearing Gases (O₂, CO₂, CO, NO, and NO₂)

Molecules
The formation of the oxygen negative ion O− from simple molecules such as O2, CO2, CO, NO, and NO2 is of fundamental importance in environmental, atmospheric, and biological processes.

Characteristics of negative ion generation in large area negative ion source based on cavity ring-down spectroscopy

He jishu
BackgroundThe neutral beam injection system (NBI) has the highest heating efficiency and the clearest physical mechanism, so it has become one of the main auxiliary heating methods used in the world's large magnetic confinement controlled thermonuclear ...

MODEL PSEUDOPOTENTIAL OF THE ELECTRON - NEGATIVE ION INTERACTION

Condensed Matter Physics, 2003
Generalization of the Anderson model to describe the states of electronegative impurities in liquid-metal alloys is the main aim of the present paper. The effects of the random inner field on the charge impurity states is accounted for selfconsistently ...

Guest Ion‐Dependent Reaction Mechanisms of New Pseudocapacitive Mg3V4(PO4)6/Carbon Composite as Negative Electrode for Monovalent‐Ion Batteries

Advanced Science, 2023
Polyanion‐type phosphate materials, such as M3V2(PO4)3 (M = Li/Na/K), are promising as insertion‐type negative electrodes for monovalent‐ion batteries including Li/Na/K‐ion batteries (lithium‐ion batteries (LIBs), sodium‐ion batteries (SIBs), and ...

A negative ion source for alkali ions [PDF]

Nuclear Instruments and Methods, 1980
An ion source is described which delivers negative alkali ions. With this source, which consists of a duoplasmatron and a charge exchange canal with alkali vapour, negative Li, Na and K ions are produced. The oven in which alkali metals are evaporated can reach temperatures up to 575°C.

Alternative solutions to caesium in negative-ion sources: a study of negative-ion surface production on diamond in H2/D2 plasmas

New Journal of Physics, 2017
This paper deals with a study of H ^− /D ^− negative ion surface production on diamond in low pressure H _2 /D _2 plasmas. A sample placed in the plasma is negatively biased with respect to plasma potential.
