X-ray and low energy photon sources (6 keV – 80 keV)

Application

These sources have been designed to minimize self-absorption of low energy photons, so they are suitable for calibrating X-ray spectrometers such as Si(Li) detectors. For energy calibration only, a more robust source design is used.

Construction

A thin deposit of active material 5mm in diameter is heat sealed between plastic foils. The foils are mounted in an aluminium frame 25mm in diameter, 3mm thick (drawing VZ-1562-001). The 20 -37 kBq sources are sealed between foils 0.1mm and 0.015mm thick, with the thinner foil on the engraved side.

Robust source for energy calibration

Construction

The radioactive isotope is absorbed in an ion-exchange bead approximately 1mm in diameter. The bead is fixed inside a solid plastic capsule. The active bead is visible, and located at the geometric centre of the source. This source is uncalibrated and is intended for energy calibration only.
