论文摘要
随着中微子天文学的兴起，使用大容量检测器阵列，光学介质和光传感器的校准改进已成为减少探测器系统学的重要手段。为了提高对探测器体积及其仪器的了解，我们开发了一种绝对校准的，自我监测的，各向同性，纳米秒，高强度校准光源，称为“精密光学校准模块”（POCAM）。现在，该仪器的第三次迭代是为ICECUBE升级中的应用开发的，但是，通过模块化的仪器通信和同步后端，可以为任何大容量光电探测器阵列提供校准光源标准。这项工作总结了POCAM和所有相关设备特征的功能原理及其精确校准程序。后者提供指纹特征的仪器，并了解发射光脉冲的绝对和相对行为及其温度依赖性。
With the rise of neutrino astronomy using large-volume detector arrays, calibration improvements of optical media and photosensors have emerged as significant means to reduce detector systematics. To improve understanding of the detector volume and its instrumentation, we developed an absolutely-calibrated, self-monitoring, isotropic, nanosecond, high-intensity calibration light source called "Precision Optical Calibration Module" (POCAM). This now third iteration of the instrument was developed for an application in the IceCube Upgrade but, with a modular instrument communications and synchronization backend, can provide a calibration light source standard for any large-volume photodetector array. This work summarizes the functional principle of the POCAM and all related device characteristics as well as its precision calibration procedure. The latter provides fingerprint-characterized instruments with knowledge on absolute and relative behavior of the emitted light pulses as well as their temperature dependencies.
