Influence of surface materials on the volume production of negative ions in a radio-frequency driven hydrogen plasma

Autor: Ellis, J., Branson, J., Niemi, K., Wagenaars, E., Gans, T.

Negative atomic hydrogen ion (H$^{-}$) densities were measured in a pulsed low-pressure E-mode inductively-coupled radio-frequency (rf) driven plasma in hydrogen by means of laser photodetachment and a Langmuir probe. This investigation focuses on th
