论文摘要

Calice合作正在开发高度颗粒状的电磁和HADRONIC量热计,用于未来的能量边界电子峰面积的探测器。在成功测试了物理原型之后,基于可扩展对撞机检测器的设计和构造技术,建立了模拟强子量热量计的技术原型。该原型由钢吸收器结构和小闪烁瓷砖的活性层组成,这些磁极瓷砖由直接耦合的sipm读出。每一层的活动面积为$ 72 \ times 72 \,{\ rm cm}^{2} $,瓷砖大小为$ 3 \ times 3 \,{\ rm cm cm}^{2} $。该原型具有$ 38 $的活动层,具有近22,000美元的读出渠道,其总厚度为$ 4.4 $ $核交互的长度。专用的读取电子设备为每次命中的时间冲压提供了预期的分辨率约为$ 1 \,{\ rm ns} $。该原型于2017年构建,并在DESY进行了梁测试。它记录了2018年在CERN的测试梁的不同能量的兆次,强子淋浴和电子淋浴。在本文中,描述了原型的设计,其构造和调试。详细介绍了用于校准检测器的方法,并提出了均匀性和稳定性的性能。

The CALICE collaboration is developing highly granular electromagnetic and hadronic calorimeters for detectors at future energy frontier electron-positron colliders. After successful tests of a physics prototype, a technological prototype of the Analog Hadron Calorimeter has been built, based on a design and construction techniques scalable to a collider detector. The prototype consists of a steel absorber structure and active layers of small scintillator tiles that are individually read out by directly coupled SiPMs. Each layer has an active area of $72 \times 72\,{\rm cm}^{2}$ and a tile size of $3 \times 3\,{\rm cm}^{2}$. With $38$ active layers, the prototype has nearly $22,000$ readout channels, and its total thickness amounts to $4.4$ nuclear interaction lengths. The dedicated readout electronics provide time stamping of each hit with an expected resolution of about $1\,{\rm ns}$. The prototype was constructed in 2017 and commissioned in beam tests at DESY. It recorded muons, hadron showers and electron showers at different energies in test beams at CERN in 2018. In this paper, the design of the prototype, its construction and commissioning are described. The methods used to calibrate the detector are detailed, and the performance achieved in terms of uniformity and stability is presented.
