TPB涂层光导探测器光衰减的模拟

A Simulation of the Optical Attenuation of TPB Coated Light-guide Detectors

B. J. P. Jones

摘要:

本说明描述了简单的模拟,以了解丙烯酸光导在空气和氩气中工作的衰减行为,其特征在于在\cite{Baptista:2012bf}。虽然这些模拟仅处于玩具模型的复杂程度,但它们说明了有趣的非指数光衰减效应以及在氩气和空气环境中操作基于光导的检测器之间的差异。我们调查的表面吸收,表面粗糙度和波长依赖性的影响,并使用一个模型调整在空气中测量的光导衰减曲线,使预测的光导在氩气中的衰减曲线。将该曲线与来自液氩试验台的数据进行比较,观察到了对简单指数模型的改进。

英文摘要:

This note describes simple simulations which were performed in order to understand the attenuation behaviors of acrylic light-guides operated in air and argon, which were characterized in \cite{Baptista:2012bf}. Whilst these simulations are only at the level of sophistication of a toy model, they illustrate interesting non-exponential light attenuation effects and the differences between operating light-guide based detectors in argon and air environments. We investigate the effects of surface absorption, surface roughness and wavelength dependence, and use a model tuned on the light-guide attenuation curve measured in air to make a prediction of the light-guide attenuation curve in argon. This curve is compared with data from a liquid argon test stand, and an improvement over a simple exponential model is observed.
