Numerical simulation of the charge balance and temperature evolution in an electron beam ion trap

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2009
A computer code has been developed to simulate and study the evolution of ion charge states inside the trap region of an electron beam ion trap. In addition to atomic physics phenomena previously included in similar codes such as electron impact ...

Revisiting benzene cluster cations for the chemical ionization of dimethyl sulfide and select volatile organic compounds [PDF]

open access: yesAtmospheric Measurement Techniques, 2016
Benzene cluster cations were revisited as a sensitive and selective reagent ion for the chemical ionization of dimethyl sulfide (DMS) and a select group of volatile organic compounds (VOCs).

Electron cyclotron resonance charge breeder plasma parameters from the modeling of 1+ beam stopping

open access: yesPhysical Review Accelerators and Beams, 2021
As a part of SPIRAL1 upgrade, several experiments were carried out to understand the transport of 1+ (monocharged) ion beam through the SP1 ECR charge breeder ion source and to investigate the physical processes involved in charge breeding.

Atomic collisional data for neutral beam modeling in fusion plasmas

open access: yesNuclear Fusion, 2023
The injection of energetic neutral particles into the plasma of magnetic confinement fusion reactors is a widely-accepted method for heating such plasmas; various types of neutral beam are also used for diagnostic purposes.

CID fragmentation, H/D exchange and supermetallization of Barnase-Barstar complex

open access: yesScientific Reports, 2017
The barnase-barstar complex is one of the most stable protein-protein complexes and has a very wide range of possible applications. Here we report the use of top-down mass spectrometry for the investigation of the structure of this complex, its ...

Testing a prediction model for the H-mode density pedestal against JET-ILW pedestals

open access: yesNuclear Fusion, 2023
The neutral ionisation model proposed by Groebner et al (2002 Phys. Plasmas 9 2134) to determine the plasma density profile in the H-mode pedestal, is extended to include charge exchange processes in the pedestal stimulated by the ideas of Mahdavi et al (

Linear fractional charge behavior in density functional theory through dielectric tuning of conductor-like polarizable continuum model [PDF]

open access: yes, 2022
A property of exact density functional theory is linear fractional charge behavior as electrons are added or removed from a molecule. Typical density functional approximations (DFAs) exhibit delocalization error, which overstabilizes this fractional ...

On the ion and electron temperature recovery after the ELM-crash at ASDEX upgrade

open access: yesNuclear Materials and Energy, 2019
The access to fast measurements, i.e. Δt ≈ 100 µs, of the ions and the electrons during an entire edge localized cycle (ELM) reveals asymmetries in the recovery of the maximum edge gradients.
