[en] Initial results from a study of EUV emissions from the 2XIIB experiment are reported. Time-dependent brightness measurements of deuterium, oxygen, nitrogen, carbon and titanium emissions from the central 2XIIB plasma have been made. The deuterium Lyman alpha brightness is 1.5 x 10¹⁷ photons sec^-1cm^-2sr^-1. The Lyman alpha time development and broad spectral profile are consistent with other knowledge of the 2XIIB plasma. Oxygen is the dominant impurity in 2XIIB. The 0 VI 1032 A brightness is 1.65 x 10¹⁸ photons sec^-1cm^-2sr^-1. The oxygen concentration is 2% and its estimated confinement lifetime is 300 μs; this may imply mirror confinement of the oxygen ions. Nitrogen and carbon concentrations are 0.4% and 0.3%, respectively. It is not certain whether these impurities are mirror confined. The titanium concentration is believed to be low compared to that of oxygen. The power loss from the central plasma due to radiation by and ionization of light impurities is approximately 60 kW, which is 4% of the power deposited by the neutral beams. Further studies of impurity sources and penetration are now being performed
