Identification of the extraction structure of H− ions by Hα imaging spectroscopy
Extraction structure of negative hydrogen ions (H ^− ) (i.e. the regions where H ^− ions are effectively extracted from the plasma) was obtained using hydrogen Balmer- α (H _α ) imaging spectroscopy and cavity ring-down spectroscopy. The H ^− ion density increases after caesium (Cs) seeding through...
