摘要: A cylindrical inductively coupled plasma source (ICPS) is optimized for nitrogen atom production. How to operate in the bright mode (H-mode) pure at relatively low applied power explained. Actinometry developed a quantitative determination of dissociation fraction ICPS. These results are compared with those obtained outside ICPS by modulated beam mass spectrometry. qualitative agreement between dissociative inside and The higher magnitude given spectrometry that derived from actinometry explained contribution recombination near exit hole up 0.7 observed Some also reported argon–nitrogen gas mixtures.
