The barrel calorimeter is part of the new spectrometer installed in Hall D at Jefferson Lab for the GlueX experiment. The calorimeter was installed in 2013, commissioned in 2014 and has been operating routinely since early 2015. The detector configuration, associated Monte Carlo simulations, calibration and operational performance are described herein. The calorimeter records the time and energy deposited by charged and neutral particles created by a multi-GeV photon beam. It is constructed as a lead and scintillating-fiber calorimeter and read out with 3840 large-area silicon photomultiplier arrays. Particles impinge on the detector over a wide range of angles, from normal incidence at 90 degrees down to 11.5 degrees, which defines a geometry that is fairly unique among calorimeters. The response of the calorimeter has been measured during a running experiment and performs as expected for electromagnetic showers below 2.5 GeV. We characterize the performance of the BCAL using the energy resolution integrated over typical angular distributions for $π^0$ and $η$ production of $σ_E/E$=5.2\%/$\sqrt{E(\rm{GeV})} \oplus$ 3.6\% and a timing resolution of $σ$\,=\,150\,ps at 1\,GeV.

The Monitoring System of the End-Cap Calorimeter in the Belle II experiment
Belle II实验目前正在KEK（日本筑波）的SuperKEKB电子-正电子对撞机上进行第二阶段操作。该探测器是KEKB对撞机上Belle实验的升级，它被优化用于研究罕见的B衰变，对标准模型之外的新物理信号也很敏感。电磁量热计（ECL）是基于CsI（Tl）闪烁晶体。它分裂成一个桶和两个环形端盖区域，根据对撞机的非对称设计，后者被命名为向前和向后。CsI（Tl）晶体以可承受的成本提供高光输出，但其产量随温度变化，并且由于对水分的强烈化学亲和力，可能会被湿度永久损坏。然后，每个ECL区域都配备了热敏电阻和湿度探头，以监测环境数据。虽然传感器和布线都继承了原来的百丽设计，ECL监测系统已完全重新设计。在本文中，我们提出了硬件和软件架构部署的2112 CsI（Tl）晶体安排在向前和向后的端盖。单板计算机（SBC）是专为嵌入式应用而设计的。对于传感器读出，已实现了基于具有本地处理能力的24位ADC的数据采集系统，并与SBC接口。EPICS应用程序通过局域网发送数据，用于遥控和显示。
