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

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 the influence of different metallic surface materials on...
