McPherson is to provide a research group from the Chinese HL-2A Tokamak at the Southwestern Institute of Physics with a vacuum ultraviolet (VUV) spectrometer.
The fusion research group will use the spectrometer to diagnose the tokamak fusion plasma in the 30nm region to learn more about spectral features related to carbon and oxygen emission. The group will also study metal ions of iron, titanium and aluminium – the presence of which can influence fusion events and indicate the contamination of a plasma vessel.
The spectrometer was chosen for its flexibility in spectral data collection. It allows users to use very short wavelengths in high-energy regions. It is hoped to be used in studies of how the plasma changes over time.
