Abstract

The thermally-transferred optically stimulated luminescence (TT-OSL) responses of chemically-purified fine-grained quartz from a lava-baked aeolian sediment from Datong (China) are presented. Our main focus is to examine the suitability of the test dose TT-OSL and OSL response to monitor sensitivity changes during SAR measurements. It is found that, in contrast to the test dose OSL, the TT-OSL response to a test dose can successfully monitor sensitivity changes, and a high-temperature blue-light bleach (600s at 260°C) in the middle of each SAR cycle is necessary to minimize interference with the test dose TT-OSL signal. The revised SAR TT-OSL protocol was tested by dose recovery tests on two very young (quartz OSL De20% of the given dose) in this revised SAR TT-OSL protocol.
