Negative hydrogen/deuterium ions can be formed by processes occurring in the plasma
volume and on surfaces facing the plasma. The principal mechanisms leading to the …

Interaction of atomic and molecular particles with dielectric surfaces has been attracting
considerable attention over the past years, in order to understand various fundamental …

A model of the collisional kinetics of energetic hydrogen atoms, molecules and ions in pure
H 2 discharges is used to predict H α emission profiles and spatial distributions of emission …

We present the results of an experimental and theoretical study of H− formation in collisions
of 1 to 4 keV positive and negative hydrogen ions with clean Mg, Al, and Ag surfaces. Ion …

In this study, a hydrogen ionic plasma with relatively low residual fractional electron
concentration (ne/n+∼ 10− 2) is generated using an aluminum plasma grid for the …

We theoretically investigate the electron transfer dynamics during the reflection of hydrogen
atoms on an Al (100) surface for a wide range of collision energies below 6 keV. We find a …

We measure H− negative ions by means of a mass spectrometer in a helicon plasma
reactor. The H 2 plasma operates at a low injected RF power (50–300 W), in a capacitive …

We present the results of a study of H− and O− formation in collisions between 0.5–4 keV
hydrogen ions and oxygen ions and atoms with an Si surface. Measurements of scattered …

The dependence of the negative-ion fractions on incident energy and angle is reported for
8.5–22.5 keV F− ions scattered from a Si (100) surface at a fixed scattering angle of 38. The …

In this paper we report measurements of the positive (H+) and negative (H−) ion fractions
after H+ scattering from a highly oriented pyrolytic graphite (HOPG) surface. The …
