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.

¹⁾ Source should be wipe-tested regularly.

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.
