Influence of surface materials on the volume production of negative ions in a radio-frequency driven hydrogen plasma
J. Ellis, J. Branson, K. Niemi +2
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…

Negative-hydrogen-ion production from a nanoporous 12CaO 7Al2O3 (C12A7) electride surface
Mamiko Sasao, Roba Moussaoui, Dmitry Kogut +5
A high production rate of negative hydrogen ion was observed from a nanoporous C12A7 electride surface immersed in hydrogen/deuterium low-pressure plasmas. The target was biased at…
