论文摘要
在Calice合作中开发了模拟强子量热仪（AHCAL），以在未来的Lepton Collider进行实验。它是一种采样量热仪，具有交替的钢吸收板和塑料闪烁瓷砖作为活性材料。在瓷砖设计的SIPM中，瓷砖直接耦合到硅光电层（SIPM）。前端电子设备被整合到量热计的活性层中。它们是根据线性加速器的光束结构快速循环而设计的，可用于低功耗。在2017年和2018年，已经建立了一个新的大型原型，其38个活性层为72x72 cm $^{2} $大小。每个活动层由四个读取板组成，每个读数板都有四个36 Channel Spiroc2e读数ASIC，每层产生576个通道。该原型已设计用于批量生产和组装技术：它使用注射式瓷砖，这些瓷砖在反射箔中半自动包装，使用拾取机器组装，瓷砖和电子组件组装，并且在组装过程中测试了所有检测器零件。在DESY委托拥有约22,000个通道的原型，并在CERN SPS上获取了Muon，Electron和Pion数据，以证明具有可扩展探测器设计的SIPM-on-tile量热计概念的能力以及大型原型的可靠操作。该程序概述了大型Calice AHCAL技术原型的校准结果。
The Analogue Hadron Calorimeter (AHCAL) is being developed within the CALICE collaboration for experiments at a future lepton collider. It is a sampling calorimeter with alternating layers of steel absorber plates and plastic scintillator tiles as active material. In the SiPM on tile design, the tiles are directly coupled to silicon photomultipliers (SiPMs). The front-end electronics are integrated into the active layers of the calorimeter. They are designed for low power consumption by rapidly power cycling according to the beam structure of a linear accelerator. In 2017 and 2018, a new large prototype with 38 active layers of 72x72 cm$^{2}$ size has been built. Each active layer consists of four readout boards with four 36 channel SPIROC2E readout ASIC each, resulting in 576 channels per layer. The prototype has been designed for mass production and assembly techniques: It uses injection-moulded tiles which were wrapped semi-automatically in reflector foil, tiles and electronics components were assembled using pick-and-place machines and all detector parts were tested during assembly. The prototype with ~22,000 channels was commissioned at DESY and took muon, electron and pion data at the CERN SPS to demonstrate the capabilities of a SiPM-on-tile calorimeter concept with scalable detector design and the reliable operation of a large prototype. This proceedings gives an overview of the calibration results of the large CALICE AHCAL technological prototype.
