提出了一种新型的质子成像装置，可以提高强子治疗的准确性高密度玻璃。需要高密度的增透玻璃来构建可附接到台架的具有成本效益的紧凑型热量计。本报告总结了对含有镧、钆和钨等重元素的铕、铽和铈掺杂玻璃的研究。样品的密度达到5.9g/cm ~ 3，其300 - 600 nm发射与商用光电探测器的峰值阴极灵敏度完全重叠。开发的玻璃不需要任何特殊的淬火，可以很容易地浇注，这使得它们成为生产各种几何形状的良好候选者。本文报道了玻璃的制备条件、光学性能和物理性能的初步测试结果。(C)© 2016 Elsevier B. V.版权所有。
High-density scintillating glasses are proposed for a novel proton-imaging device that can improve the accuracy of the hadron therapy. High-density scintillating glasses are needed to build a cost effective, compact calorimeter that can be attached to a gantry. This report summarizes the study on Europium, Terbium, and Cerium-doped scintillating glasses that were developed containing heavy elements such as Lanthanum, Gadolinium, and Tungsten. The density of the samples reach up to 5.9 g/cm(3), and their 300 -600 nm emission overlaps perfectly with the peak cathode sensitivity of the commercial photo detectors. The developed glasses do not require any special quenching and can be poured easily, which makes them a good candidate for production in various geometries. Here, the glass making conditions, preliminary tests on optical and physical properties of these scintillating, high-density, oxide glasses developed for a novel medical imaging application are reported.
