Under European Union H2020-MSCA-RISE-2018 research programme (IN TIME project - G.A. n.823934), a portable luminescence dating prototype for in-situ examination has been designed by Alma Sistemi S.r.l., Guidonia, Italy. The development of this instrument is of great relevance since, compared to current luminescence dating technologies and considering its reduced dimensions and weight, the presence of the air-cooling system (vs nitrogen) and the use of X-ray (vs radiative source) qualify the instrument for direct and safe use in the field. The prototype has been validated by University of Sassari, Sassari, Italy, using different samples and results compared with equivalent laboratory instrument (Risø TL/OSL Reader model TL/OSL-DA-20). The instrument finds practical use in geological and archaeological field applications with a time range that spans from the last few decades up to one million years. In the archaeological field, this technique is applied not only directly to artifacts of interest, but also to the geological sediments in excavation sites. At this stage, the instrument can perform a basic SAR protocol and accurately measure the response luminescence signal after different irradiations time and thus measure the natural dose of the natural sediment sample.
