Enhancements in Luminescence Measurement Techniques

Radiation Protection Dosimetry, 2002
New developments in the Risø TL/OSL system includes a software controlled heater fitted underneath the beta source to enable irradiation of samples at an elevated temperature. This allows investigations of competition effects from thermally shallow traps and centres. Significant additional software developments include the facility to vary linearly the

Developments in luminescence measurement techniques

Radiation Measurements, 2006
Abstract We report on our continuing investigation and development of new measurement facilities for use in irradiation, optical stimulation and luminescence signal detection; these facilities have potential application to all forms of luminescence-based retrospective dosimetry, and are particularly intended for use with the Riso TL/OSL reader.

Luminescence measurements with CCDs

IECON '98. Proceedings of the 24th Annual Conference of the IEEE Industrial Electronics Society (Cat. No.98CH36200), 2002
A multi-parametric measurement system of low light intensity based on a CCD is evaluated in this article. The light arrives through several optic fibres from the corresponding sample or chemical sensor phase, where the luminous phenomenon is produced.

Measurement of Short Luminescence Decay Times

Applied Optics, 1967
The stroboscopic technique for measuring luminescence decay times and for time-resolved spectroscopy can be greatly simplified by using a photomultiplier which has a control mesh behind the photocathode. This makes it possible to cut off the tube output by applying a negative bias of 1-2 V to the mesh; then the tube can be gated on for short periods by
