论文摘要
本文介绍了基于可移动的137CS伽马射线源的校准和监视系统的设计，构建和使用，用于Atlas Tile Calorimeter（Tilecal）。这些来源是由水基液体通过横穿所有量热计细胞的试管推动的，产生了信号，这些信号精确地表征了每个瓷砖的响应，从而提供了非常细粒度，准确的数据，以了解tilecal对颗粒的响应。该系统已被用来指导和控制所有Tilecal模块的光学仪器的质量，以设置和均衡物理数据响应的动态范围，并设置读取系统的能量尺度。在地图集洞穴中，对整个检测器对137CS源的响应的定期测量允许监测所有量热计细胞的均匀性和稳定性，并保持对其能量校准的精确知识。描述了源液压驱动系统的硬件和软件，数据采集系统和数据处理算法的设计。最后，显示了此两年计划的结果。
This article describes the design, construction and use of a calibration and monitoring system, based on movable 137Cs gamma-ray sources, for the ATLAS Tile Calorimeter (TileCal). The sources, propelled by a water-based liquid through tubes that traverse all the calorimeter's cells, produce signals that precisely characterise the response of each tile, thereby providing very granular and accurate data on the response of TileCal to particles. The system has been used to guide and control the quality of the optical instrumentation of all TileCal modules, to set and equalise the dynamic range of the response to physics data, and to set the energy scale of the readout system. In the ATLAS cavern, periodic measurements of the whole detector's response to 137Cs sources allow monitoring the uniformity and stability of all the calorimeter's cells as well as maintaining precise knowledge of its energy calibration. The design of the source hydraulic drive system's hardware and software, the data acquisition system and the data processing algorithms are described. Finally, the results of this two-decade program are shown.
