Correlations between density distributions, optical spectra, and ion species in a hydrogen plasma (invited)
Abstract
An experimental study of plasma distributions in a 2.45 GHz hydrogen discharge operated at
100 Hz repetition rate is presented. Ultrafast photography, time integrated visible light emission
spectra, time resolved Balmer-alpha emission, time resolved Fulcher Band emission, ion species mass
spectra, and time resolved ion species fraction measurements have been implemented as diagnostic
tools in a broad range of plasma conditions. Results of plasma distributions and optical emissions
correlated with H

ion currents by using a Wien filter system with optical observation
capability are reported. The magnetic field distribution and strength is found as the most critical
factor for transitions between different plasma patterns and ion populations.
