- Abstract
- The vibrational population distribution of the electronic ground state of H2 in the expansion region
of a negative ion source is investigated using a kinetic Monte Carlo model. Operative conditions are
referred to the inductively coupled plasma radio frequency negative ion source developed at
IPP-Garching. The different excitation and relaxation processes are discussed, both bulk and surface
contributions. In particular, due to the relatively high plasma density, the relevant role of direct low
energy electron-impact excitation, surface Auger neutralization, and vibration-translation
deactivation are recovered. Results of the present model will be used as input data for the neutral
source model in the extraction region. (literal)
