我们报道了用于未来国际直线对撞机探测器的高粒度瓦片强子量热计原型的设计、构造和性能。闪烁的瓷砖通过波长移动的光纤读出，这些光纤将闪烁光引导到一种新型的光电探测器--硅光电倍增管。一个原型已经在DESY使用正电子测试束进行了测试。并与配备多通道真空光电倍增管的参考样机进行了比较。讨论了探测器的刻度、噪声、线性度和稳定性，并对1-6GeV正电子束的能量响应进行了模拟比较。结果表明，硅光电倍增管非常适合作为量热计中的光电探测器，因此被选作1m~3量热计的样机，用于强子束的工作。
We report on the design, construction and performance of a prototype for a high-granularity tile hadronic calorimeter for a future international linear collider detector. Scintillating tiles are read out via wavelength-shifting fibers that guide the scintillation light to a novel photodetector, the silicon photomultiplier. A prototype has been tested using a positron test beam at DESY. The results are compared with a reference prototype calorimeter equipped with multichannel vacuum photomultipliers. Detector calibration, noise, linearity and stability are discussed, and the energy response in a 1–6GeV positron beam is compared with simulations. The present results demonstrate that the silicon photomultiplier is well-suited as photodetectors in calorimeters and thus has been selected for the construction of a 1m3calorimeter prototype to operate in hadron beams.
