本文总结了Riscycle划分TL/OSL阅读器的最新发展。这些新的发展包括一个高温辐照设施，已扩大到测量可变温度辐射发光（RL）在β辐照。该RL设备允许在相同的软件控制自动序列中测量TL、OSL和RL。为了提供替代Sr-90 β源的方案，研究了软件控制的小型X射线发生器的性能。这具有提供跨越超过三个数量级直至超过2戈伊/s的剂量率范围的优点。一个单独的漂白设施也被添加到读者，新的强大的红外（IR）发光二极管已取代红外激光二极管在一般的OSL单位，和红外激光器已被列入单粒OSL附件。本文介绍了这些新的设备，并说明了它们的应用与代表性的测量。(C)2003爱思唯尔科技有限公司版权所有。
This paper summarises recent developments in the Riscircle divide TL/OSL reader. These new developments include an elevated temperature irradiation facility that has been expanded to measure variable temperature radioluminescence (RL) during beta irradiation. This RL facility allows the measurement of TL, OSL and RL in the same software-controlled automatic sequence. To provide an alternative to the Sr-90 beta source, the performance of a software-controlled mini X-ray generator has been investigated. This has the advantage of providing a range of dose rates spanning more than three orders of magnitude up to more than 2 Gy/s. A separate bleaching facility has also been added to the reader, new powerful infrared (IR) light-emitting diodes have replaced the IR laser diode in the general OSL unit, and an IR laser has been included in the single-grain OSL attachment. This paper describes these new facilities, and illustrates their applications with representative measurements. (C) 2003 Elsevier Science Ltd. All rights reserved.
