Optical Emission Spectroscopy Measurements of keV Apparent Ion Temperatures in Avalanche Energy’s Centrifugal Mirror Machine

"This paper presents the first optical emission spectroscopy (OES) measurements demonstrating that Avalanche Energy’s very compact centrifugal mirror produces ion populations with density-weighted apparent ion temperatures in the 1.4–1.6 keV range with values in excess of 2 keV."
