Application 

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.

Construction

A thin deposit of active material is glued between Mylar foils (drawing VZ-486-001), 0.9mg/cm² thick, or between titanium foils (drawing VZ-392-001) each 2.4mg/cm² thick. The foils are supported in an aluminium frame 25mm in diameter, 3mm thick. The diameter of the active deposit is approximately 5mm.
