Résumé

In this paper, we address the experimental details of a radioactive evaporation source that can potentially be used to produce X-rays radioactive devices at a nanometer scale. The source consists of Rh wire that has been irradiated in a 14 MeV cyclotron. A 22 keV X-ray emitter results from the Rh(p,n)Pd nuclear reaction. Pd is currently widely used in brachytherapy. Thanks to physical differences in evaporation and melting temperature but also diffusion coefficients between Pd and Rh, Pd is extracted from the raw material by dry distillation at high temperature (1000-1470 °C) and under vacuum (2×10 mbar). Spectroscopic gamma analysis of the raw material and atoms condensed on the substrates are presented. Diffusion coefficients are also deduced. © 2007 Elsevier B.V. All rights reserved.
