Application<\/b><\/p>\r\n

These sources are intended for calibrating the energy response of magnetic or solid state electron detectors. The calibrated Bi-207 source can also be used to estimate the detection efficiency. Radionuclides have been chosen that have intense, easily resolvable, electrons from internal conversion.<\/span><\/p>\r\n

Construction<\/b>\r\n<\/span><\/p>\r\n

A thin deposit of active material is glued between Mylar foils (drawing VZ-4169-001<\/a>), 0.9mg\/cm2<\/sup>\u00a0thick, or between titanium foils (drawing VZ-4148-001<\/a>) each 2.4mg\/cm2\u00a0<\/sup>thick. The foils are supported in an aluminium frame 25mm in diameter, 3mm thick. The diameter of the active deposit is approximately 5mm.<\/span><\/p>\r\n
