AI 中文摘要
嵌入波长移位光纤的闪烁体探测器已在粒子物理实验中应用数十年，这类探测器被制成方形、矩形和三角形轮廓。三角形探测器阵列的优势在于，可利用相邻探测器的相对光产额进行插值，大幅提升其位置分辨率。本文报道了对这类闪烁体 hodoscope 位置分辨率的束流测试研究，并将结果与模拟计算对比。研究发现，其位置分辨率较单纯使用光纤间距的结果提升了一个数量级。
英文摘要
Scintillator counters employing embedded wavelength-shifting fibers have been used in particle physics experiments for several decades. Such counters have been produced with square, rectangular, and triangular profiles. An advantage of arrays of triangular counters is that their position resolution can be greatly enhanced by interpolation between adjacent counters using their relative light yields. We report here on a testbeam study of the position resolution of such a scintillator hodoscope and compare the results to a simulation. We find an order of magnitude improvement in the position resolution over that found by simply using the fiber separation.
