论文摘要
闪烁的均匀探测器代表电磁量热法的最新技术。此外，可以利用当前被忽视的最常见无机闪烁体的结晶性质，以在紧凑度和能量分辨率方面取得出色的性能。实际上，最近通过轴向/艾略特实验证明，当入射粒子轨迹与$ \ sim 1^\ circe $ \ sim 1^\ circe $ \ sim 1^\ circe $ \ sim \ sim 1^\ $ \ sim \ sim $ $ \ sim \ sim $ $ \ sim \ sim时，在PWO内部的辐射长度的强烈减小以及随后的闪烁光的闪烁光的增强。已经开发了基于SIPM的系统，可以通过测量PWO样品发出的闪烁光直接探测这种显着效果。相同的概念可以应用于全尺度检测器，该检测器的设计比目前和将来的实验的兴趣范围内的目前可实现且无与伦比的分辨率要紧凑得多。
Scintillating homogeneous detectors represent the state of the art in electromagnetic calorimetry. Moreover, the currently neglected crystalline nature of the most common inorganic scintillators can be exploited to achieve an outstanding performance boost in terms of compactness and energy resolution. In fact, it was recently demonstrated by the AXIAL/ELIOT experiments that a strong reduction in the radiation length inside PWO, and a subsequent enhancement in the scintillation light emitted per unit thickness, are attained when the incident particle trajectory is aligned with a crystal axis within $\sim 1^\circ$. A SiPM-based system has been developed to directly probe this remarkable effect by measuring the scintillation light emitted by a PWO sample. The same concept could be applied to full-scale detectors that would feature a design significantly more compact than currently achievable and unparalleled resolution in the range of interest for present and future experiments.
