Measurement of ionization, charge exchange and ion confinement times in charge breeder ECR ion sources with short pulse 1+ injection of metal ions [PDF]

open access: yes, 2021
International audienceThe Consecutive Transients (CT) method is used for estimating the characteristic times of ionization, charge exchange and confinement within the plasma of a Charge Breeder Electron Cyclotron Resonance Ion Source (CB-ECRIS).

Double Doping of a Low-Ionization-Energy Polythiophene with a Molybdenum Dithiolene Complex [PDF]

open access: yes, 2022
Doping of organic semiconductors is crucial for tuning the charge-carrier density of conjugated polymers. The exchange of more than one electron between a monomeric dopant and an organic semiconductor allows the polaron density to be increased relative ...

Interaction of Be4+ and Ground State Hydrogen Atom—Classical Treatment of the Collision

open access: yesAtoms, 2020
The interaction between Be4+ and hydrogen atom is studied using the three-body classical trajectory Monte Carlo method (CTMC) and the quasiclassical trajectory Monte Carlo method of Kirschbaum and Wilets (QTMC-KW).

Study of field ionization in the charge exchange injection for the IPNS Upgrade [PDF]

open access: yesProceedings Particle Accelerator Conference, 2002
The proposed 1-MW neutron spallation source is a rapid-cycling synchrotron (RCS) with a design intensity of 1.04/spl times/10/sup 14/ protons. A H/sup -/ beam from the linac is injected into the synchrotron via the charge exchange process. Due to the high intensity of the beam, the minimization of beam loss is one of the primary concerns. In this paper,

On coupling fluid plasma and kinetic neutral physics models

open access: yesNuclear Materials and Energy, 2017
The coupled fluid plasma and kinetic neutral physics equations are analyzed through theory and simulation of benchmark cases. It is shown that coupling methods that do not treat the coupling rates implicitly are restricted to short time steps for ...

Tailoring of ion species composition in complex plasmas with charge exchange collisions [PDF]

open access: yes, 2005
A generic approach towards tailoring of ion species composition in reactive plasmas used for nanofabrication of various functional nanofilms and nanoassemblies, based on a simplified model of a parallel-plate rf discharge, is proposed. The model includes

Oxygen ion energy distribution: Role of ionization, resonant, and nonresonant charge-exchange collisions [PDF]

open access: yes, 2018
Capacitively coupled rf discharge operating in oxygen/argon mixtures has been investigated using the particle-in-cell/Monte Carlo method. The roles of ionization, resonant and nonresonant charge-exchange collisions in the formation of ion energy ...
