Abstract

The discharge characteristics of a Streaming Neutral Gas Injection Hollow Cathode was investigated. The current–voltage plots of gas discharges for different gas ratios of hydrogen (H₂) and acetylene (C₂H₂) were obtained and compared with plots for a typical DC plasma source operating on similar electrode configuration and ambient pressure by utilizing a separate gas inlet. The SNGI’s capability to operate in glow discharge mode and arc discharge mode was demonstrated in relation to future work on plasma assisted deposition of carbonaceous films.
