Abstract

A separator of monoenergetic electrons is described, in which two kinds of assemblies of “miniorange”-type magnetic filters (six magnets in each) are used. The 207Bi isotope with an activity of 240 kBq (7 μCi) that emits K 1063 and K 1770 conversion electrons serves as the electron source. For different kinds of assemblies, the intensity of electrons with energies of ∼970 and ∼1680 keV is accompanied by an increase in the radiation intensity by factors of 3 and 4, respectively, as compared to the intensities measured without magnetic filters, the energy resolution being ∼30 keV. A single cycle of chamber evacuation guarantees constancy of the instrument’s parameters for one month.
