The diffusive transport of sputtered ground-state Mg atoms in 3 He gas at ambient temperatures has been investigated by using a pulse-periodic gas discharge in a 0.3m in length and 27mm in diameter cylindrical hollow cathode. Mg atoms are sputtered from the cathode surface during the pulse. An optical-absorption technique with temporal resolution is applied to record the decay curves of the...
Measurement of the diffusion loss rate of metal atoms sputtered by a pulsed gas discharge in a vessel represents a convenient method for determination of the diffusion coefficient of metal atoms in gases (J. Phys. D 30 (1997) 1878). This measurement should be combined with an appropriate diffusion model, which takes into account the experimental geometry and the interactions of the diffusing particles...
A pulsed hollow cathode discharge in Ar and Ne is used to investigate the temporal evolution of sputtered Mg density in the afterglow phase. A diffusion model of this transport is assumed, including the process of reflection by the wall (Chantry PJ, Phelps AV, Shultz GJ. Phys Rev 1966;152:81-9 [1]; Rusinov IM, Paeva GW, Blagoev AB. J Phys D: Appl Phys 1997;30:1878-84 [2]; Suzuki S. Itoh H, Ikuta N,...
