A new luminescence detection and stimulation head for the Risø TL/OSL reader

• A new detection and stimulation head for the Risø TL/OSL reader is described.
• An example of the use of the filter changer is presented.
• The power and spatial uniformity of blue, green and IR stimulation are characterised.
• The potential of an EMCCD camera detector is described.

A new automated Detection And Stimulation Head (DASH) has been developed for the Risø TL/OSL luminescence reader to provide easy access to new technologies, new signals and new measurement methods. The automated DASH includes a filter changer and a detector changer that makes it possible to change stimulation filters (4 × 4 filter combinations possible) and detectors (3 detectors possible) as part of a measurements sequence. The new automated DASH with dedicated driver electronics does not affect the use of other attachments, and can be retrospectively fitted to existing Risø TL/OSL readers.
