摘要：

先进的粒子加速方法产生了具有宽能谱和复杂空间分布的高峰值电流离子束。开发用于高能脉冲离子的在线空间分辨能谱仪至关重要。本文介绍了一种基于闪烁纤维立方体的新型能谱仪，展示了其工作原理、实验装置和全面校准，使用同步加速器产生的单能和均匀质子束进行校准。校准结果证实了该仪器的能测量范围为6-93 MeV，80 MeV时相对能量不确定度为0.6%，以及0.5 mm的像素尺寸用于束流分布重建。通过利用定制设计的能量衰减器，我们生成了复杂的质子束并用闪烁纤维立方体能谱仪（SFICS）进行了测量。结果表明该能谱仪在测量复杂质子束的能量谱和空间分布方面具有潜力。

英文摘要：

Advanced particle acceleration methods have produced high-peak-current ion beams with broad energy spread and complex spatial distribution. There is an urgent need to develop online spatial-resolved energy spectrometers for high-energy pulsed ions. This paper introduces a novel spectrometer based on a scintillation-fiber cube for online diagnosis of proton beams with broadband energy spread and complex spatial distribution. We present its working principles, experimental setup, and comprehensive calibration using monoenergetic and spatially uniform proton beams generated by a synchrotron accelerator. Calibration results confirm an energy measurement range of 6-93 MeV, a relative energy uncertainty of 0.6% at 80 MeV, and a pixel size of 0.5 mm for beam profile reconstruction. By exploiting a custom-designed energy degrader, we generated a complex proton beam and measured it with the scintillation-fiber cube spectrometer (SFICS). The results demonstrate the spectrometer's potential for online measurement of the energy spectrum and spatial distribution of complex proton beams.
