Negative Ions in Space [PDF]

open access: yesChemical Reviews, 2017
Until a decade ago, the only anion observed to play a prominent role in astrophysics was H-. The bound-free transitions in H- dominate the visible opacity in stars with photospheric temperatures less than 7000 K, including the Sun. The H- anion is also believed to have been critical to the formation of molecular hydrogen in the very early evolution of ...

Influence of positive ions on the beamlet optics for negative-ion neutral beam injectors

open access: yesNuclear 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

The Plasma Parameters of Penning Discharge with Negatively Biased Metal Hydride Cathode at Longitudinal Emission of H– Ions

open access: yesEast European Journal of Physics, 2021
The enhancement of negative ion production in a volume Penning based source could be performed by the application of metal hydride cathode. Hydrogen isotopes are stored there in a chemically bound atomic state and desorbed from the metal hydride under ...
