Non-invasive assessment of plasma parameters inside an ion thruster combining optical emission spectroscopy and principal component analysis

Abstract We present a non-invasive approach for determining plasma parameters such as electron temperature and density inside a radio-frequency ion thruster (RIT) using optical emission spectroscopy (OES) in conjunction with principal component analysis (PCA). Instead of relying on a theoretical mic...
