双读出量热技术通过同时测量由簇射发展产生的散射光（S）和切伦科夫光（C）来重建强子簇射的逐事件电磁分数。基于硅光电倍增管（SiPM）读出的新一代原型为众所周知的高能分辨率增加了前所未有的粒度。一个高度颗粒的原型（10× 10× 100 cm 3），设计完全包含电磁簇射，最近建成，并在束上合格。它由9个模块组成，每个模块由320个黄铜毛细管制成，配备有透明和透明纤维。中心模块的所有光纤都与SiPM耦合，而PMT用于其他光纤。此外，由Caen设计的新的FERS系统是SiPM读出的核心，该系统利用了CITIROC 1A ASIC的性能。DESY最近的测试光束使我们能够对读出系统进行鉴定，并定义了在宽动态范围内校准从ADC到ph-e的SiPM响应的程序。我们测量了在1-6 GeV能量范围内，每GeV的光子数和切伦科夫光的ph-e数以及量热性能。这项工作报告了系统鉴定和SiPM校准相关的测试光束结果。
The dual-readout calorimetric technique reconstructs the event-by-event electromagnetic fraction of the hadronic shower through the simultaneous measurement of scintillating (S) and Cherenkov (C) light produced by the shower development. The new generation of prototypes, based on Silicon Photomultipliers (SiPMs) readout, adds unprecedented granularity to the well-known high-energy resolution. A highly granular prototype (10× 10× 100 cm 3), designed to fully contain electromagnetic showers, was recently built and qualified on beam. It consists of 9 modules, each made of 320 brass capillaries equipped with both scintillating and clear fibers. All the fibers of the central module are coupled with SiPMs, while the PMTs are used for the others. Furthermore, the new FERS-System, designed by Caen to exploit the CITIROC1A ASICs performances, is at the core of the SiPM readout. The recent test beam at DESY allowed us to qualify the readout system and define a procedure to calibrate the SiPM response from ADC to ph-e in a wide dynamic range. We measured the number of ph-e per GeV for scintillating and Cherenkov light together with the calorimetric performances in the energy range of 1–6 GeV. This work reports the system qualification and the test beam results regarding SiPM calibration.
