在EUDET框架包JRA 3中，基于磁瓦和硅光电倍增管（SiPMs）的国际直线对撞机（ILC）模拟强子量热计（AHCAL）的概念已经被开发出来。这一概念已通过实现HCAL工作包的三个主要交付成果得到验证，即机械不锈钢吸收体结构、集成内部探测器电子设备的基本单元（包括数据采集接口电子设备）以及基于LED的SiPM的适当通道校准和增益监控系统。与实现的原型获得的测量结果证实了ILC量热计的应用程序，实现了高粒度和紧凑的开发概念的适用性。最后一代模块将用于建立一个约2500通道的原型，解决功率脉冲的重要方面，以避免热量计结构的预热。
Within the EUDET framework package JRA3, the concept of an analog hadronic calorimeter (AHCAL) for the International Linear Collider (ILC) based on scintillating tiles and silicon photomultipliers (SiPMs) has been developed. The concept has been validated by the realization of the three main deliverables of the HCAL work package, namely the mechanical, stainless steel absorber structure, the basic unit of the integrated inner detector electronics including the interface electronics to the data acquisition; and a suitable channel-wise calibration and gain monitoring system for the SiPMs based on LEDs. Measurement results obtained with the realized prototypes confirm the suitability of the developed concept for an application as ILC calorimeter, achieving a high granularity and compactness. The final generation of the modules will be used to set up a ~2500 channel prototype, addressing among others the important aspect of power-pulsing to avoid the warm-up of the calorimeter structure.
