[STT53-P01] Examination of dose dependence for quartz-TL using automated reader with four optical paths
Keywords:Thermoluminescence, dose dependence, linearity, quartz, Oninomi lava
We designed and constructed a TL/OSL (NUE–05–OSLTL) reader that has four light paths with four condensing lenses and four PMTs for choosing the suitable luminescence wave range for dating (Shitaoka, 2015). The wave ranges of the four lens and optical filter assemblages are usually 300–390 nm, 390–590 nm, 570–700 nm, and 350–700 nm.
This study used an NUE–05–OSLTL reader to measure mafic lavas in the Oninomi monogenetic volcano in northern Kyushu, Japan, which include small amounts of quartz xenocrysts (Ohta et al., 1992).
The TL-dose dependences from four wave ranges will be presented during the poster session.
