Description
A high-resolution optical emission spectrometer has been implemented as a
non-invasive diagnostic tool to investigate plasma behaviour in the GTS-LHC Electron
Cyclotron Resonance Ion Source (ECRIS). This approach aims to establish correlations
between spectral features and neutral particle densities, thereby contributing to the
development of real-time optical feedback mechanisms for the automation of ECRIS
operations. Measurements are conducted in afterglow mode, with the ion source
operating in pulsed mode at 14.5 GHz (10 Hz, 50% duty cycle). Optical spectral
data from oxygen, neon, and lead plasmas are analysed to examine the relationship
between optical emission intensities and source parameters. The practical use of
optical diagnostics as a tool for monitoring and controlling the source performance
is discussed.
