Abstract: The behavior of a palladium hollow cathode lamp discharged in deuterium was reported.The lamp was operated at pulse mode with 1μs duration at 110 Hz,900 Vand >10 Acurrent.The oscillation of discharge was observed due to the absorption and desorption of deuterium on the palladium surface layer.The analysis of discharge gas by mass spectrometry showed there was trace amount of helium-4 after 30 hours of operation.

Key words: Pd cathode filled with D2, Glow discharge, 4He mass spectrum
