摘要：

The new configuration of the electromagnetic isotope separator SIDONIE is presented. The different elements composing this separator are described. The ion beam, produced by a "Bernas-Nier" source, is separated by a high dispersion analyzing magnet. Thin targets of highly enriched isotopes are achieved by deceleration of the selected ion beam. The thickness of the targets can reach a few mg/cm(2). The homogeneity and thickness of the target are measured by Rutherford backscattering spectrometry. The isotopic enrichment factor obtained with SIDONIE is evaluated by measurement of alpha emission of a U-235 thin target. Finally, an alpha spectrum of metrology measurement of U-238 is presented. A thin layer of pure U-238 produced by SIDONIE has been measured with a high-resolution alpha spectrometer equipped with an optimized silicon junction detector. (C) 2004 Elsevier B.V.
