Abstract

The 2012 introduction of a new concept for an automated luminescence reader where detectors and detection windows can be automatically changed – the lexsygresearch - increased the versatility of luminescence measurements, especially in solid-state dosimetry. This was followed in 2014 by a miniaturized version, lexsygsmart, for more routine luminescence measurement, being equipped only with a single measurement position for a single detector plus an irradiation source. This review provides an update on the current technical specifications for both devices to measure fluorescence and phosphorescence during and after stimulation as radioluminescence, thermoluminescence, and photoluminescence. Key features of the lexsygresearch are the absence of light cross-talk to other sample aliquots and minimized radiation cross-talk while providing true non-stop operation with no breaks required for sample changes. The modular design facilitates the implementation of measurement/detection modules on a four-position detector changer and the five sample treatment positions, thus making upgrades easy. Up to three ionizing radiation sources, some with highly homogeneous fields, including an X-ray generator can be used. Luminescence stimulation can be performed either by irradiation sources, thermally or optically with up to three different wavelengths, while detection windows can be limited by combining two automatic six-position filter wheels. The lexsygresearch can be used as a spectrometer or equipped with Peltier cooling of the sample in addition to the standard heating up to 710 °C. Spatially resolved luminescence, as well as the individual laser stimulation of single mineral grains, is possible, while time-resolved/pulsing luminescence measurements not only provide means for fundamental research but also allow IRPL measurement of feldspar. For the analysis of SAR OSL data, the software LexEva provides a user interface to the R ‘Luminescence’ package, and thus, the results of dose determinations rely on a community-driven open-source project.

Lexsyg发光测量装置：现状与展望

2012年引入了自动发光读取器的新概念，其中检测器和检测窗口可以自动更改- lexsygresearch -增加了发光测量的通用性，特别是在固态剂量测定中。随后在2014年推出了小型化版本lexsygsmart，用于更常规的发光测量，仅配备了单个探测器和辐照源的单个测量位置。这篇综述提供了在刺激期间和刺激后测量荧光和磷光的设备的当前技术规范的更新，如放射发光、热发光和光发光。lexsygresearch的主要特点是没有与其他样品的光串扰和最小化辐射串扰，同时提供真正的不间断操作，无需中断样品更改。模块化设计便于在四位置检测器转换器和五个样品处理位置上实现测量/检测模块，从而使升级变得容易。可以使用多达三个电离辐射源，其中一些具有高度均匀的场，包括x射线发生器。发光刺激可以通过三种不同波长的热或光学照射源进行，而检测窗口可以通过组合两个自动六位置滤光轮来限制。lexsygresearch可以用作光谱仪或配备Peltier冷却样品除了标准加热到710°C。空间分辨发光以及单个矿物颗粒的单独激光刺激是可能的，而时间分辨/脉冲发光测量不仅为基础研究提供了手段，而且还允许对长石进行IRPL测量。对于SAR OSL数据的分析，LexEva软件为R“Luminescence”软件包提供了一个用户界面，因此，剂量测定结果依赖于社区驱动的开源项目。

期刊介绍： The journal seeks to publish papers that present advances in the following areas: spontaneous and stimulated luminescence (including scintillating materials, thermoluminescence, and optically stimulated luminescence); electron spin resonance of natural and synthetic materials; the physics, design and performance of radiation measurements (including computational modelling such as electronic transport simulations); the novel basic aspects of radiation measurement in medical physics. Studies of energy-transfer phenomena, track physics and microdosimetry are also of interest to the journal. Applications relevant to the journal, particularly where they present novel detection techniques, novel analytical approaches or novel materials, include: personal dosimetry (including dosimetric quantities, active/electronic and passive monitoring techniques for photon, neutron and charged-particle exposures); environmental dosimetry (including methodological advances and predictive models related to radon, but generally excluding local survey results of radon where the main aim is to establish the radiation risk to populations); cosmic and high-energy radiation measurements (including dosimetry, space radiation effects, and single event upsets); dosimetry-based archaeological and Quaternary dating; dosimetry-based approaches to thermochronometry; accident and retrospective dosimetry (including activation detectors), and dosimetry and measurements related to medical applications.
