摘要

The DD reaction yield (3-MeV protons) and the soft X-ray emission from a titanium (Ti) cathode surface in a periodic pulsed glow discharge in deuterium were studied at a discharge voltage of 0.8-2.45 kV and a discharge current density of 300-600 mA/cm(2). The electron screening potential U-e = 610 + 150 eV was estimated in the range of deuteron energies 0.8 keV < E-d < 2.45 keV from an analysis of the DD reaction yield as a function of the accelerating voltage. The obtained data show evidence for a significant enhancement of the DD reaction yield in Ti in comparison to both theoretical estimates ( based on the extrapolation of the known DD reaction cross section for E-d >= 5 keV to low deuteron energies in the Bosch-Halle approximation) and the results of experiments using accelerators at the deuteron energies E-lab >= 2.5 keV and current densities 50-500 mu A/cm(2). Intense emission of soft X- ray quanta (10(13)-10(14) s(-1) cm(-2)) was observed at an average energy of 1.2 - 1.5 keV. The X- ray emission intensity and the DD reaction yield enhancement strongly depend on the rate of deuterium diffusion in a thin subsurface layer of Ti cathode. (c) 2005 Pleiades Publishing, Inc.
