Description
The unsealed alpha-sources were designed and prepared to furnish 'Alpha-PXM' apparatus designed for analysis of Mars rock element composition and atmosphere by method of alpha back scattering, alpha-proton and X-ray fluorescence. The sources were prepared by high-temperature condensation of metal curium vapour on silicon substrates. The sources are silicon discs on which surfaces curium-244 as silicide is fixed. They have the following dimensions: disk of diameter 8 mm, active part of diameter 6 mm and 0.3 mm thickness. The sources activities are 5 + 1 mCi, alpha energy resolution (5.8 MeV): 1.7-2.5% FWHM, 2.9-4.5% FWTM. Performed thermovacuum (from -196 to 1000 degC), mechanical a resource tests showed the sources hold their characteristics. The sources were shown to be applied for the above mentioned analytical purposes. (author)
