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

Ion-Pair Formation in Neutral Potassium-Neutral Pyrimidine Collisions: Electron Transfer Experiments
Frontiers in Chemistry, 2019 We report novel data on ion-pair formation in hyperthermal (30–800 eV) neutral potassium collisions with neutral pyrimidine (Pyr, C4H4N2) molecules. In this collision regime, negative ions formed by electron transfer from the alkali atom to the target ...

Formation of p-, n-conductivity in semiconductors / Формирование p-, n-проводимости в полупроводниках / Formiranje provodljivosti kod poluprovodnika P-tipa i N-tipa [PDF]
Vojnotehnički Glasnik, 2018 The paper considers the energy position of negative ions of impurity atoms in the band gap of a semiconductor. Owing to the Boltzmann law, the energy levels of negative ions in the vicinity of the conduction band supply electrons to the conduction ...
