Rate coefficients for h+ ions in n-Butanol gas [PDF]
Science of Sintering, 2022 In this work we show predictions for the low energy cross sections and transport properties for the H+ ions in n-Butanol gas. These data are needed for modelling in numerous applications of technologically importance.

Influence of positive ions on the beamlet optics for negative-ion neutral beam injectors
Nuclear Fusion, 2023 Neutral beam injectors are based on the neutralization of ion beams accelerated at the desired energy. In the case of the ITER heating and diagnostic neutral beams, the target heating power translates into stringent requirements on the acceptable beamlet

Approximate Solution of the Thomas–Fermi Equation for Free Positive Ions
Atoms, 2021 The approximate solution of the nonlinear Thomas–Fermi (TF) equation for ions is found by the Fermi method. The solution is based on the new asymptotic representation of the TF ion size valid for any ionization degree.

Ionization in Positive Ion Sheaths [PDF]
Physical Review, 1928 It was found that the positive ion current to a plane auxiliary collector placed in a neon discharge had about twice the value expected from the equations of Langmuir and Mott-Smith. This increase must be due to an ionization within the sheath surrounding the electrode or to an emission of electrons from the surface of the electrode. Four different
