Optical Radiation during Sputtering of Lithium into a Noble Gas Using a Nanosecond Electron Beam

The optical radiation in a gaseous medium upon the irradiation of lithium layer with fast electron beam 5 ns duration has been studied. chamber was filled argon, krypton, or xenon at pressure 10 kPa up to 60 kPa. lines atoms appear emission spectrum temperature 650–680 K, and intensity these sharply increases increasing layer. arises from both transitions noble gas transition atom time about 20–30 ns. pulses half maximum temperatures above 800 K 60–100 wavelength 610.4 nm 140–220 670.8 krypton argon. various mechanisms for population levels during pulse are discussed.
