Abstract:
A new Monte Carlo method has been implemented to describe the angular and polarization distributions of anisotropic liquids, such as water and linear alkylbenzene (LAB), by considering orientational fluctuations of polarizability tensors. The scattered light of anisotropic liquids is depolarized with an angular distribution of 1 + (1 - ρv)/(1 + 3ρv) cos2 θ, which is modified by the depolarization ratio ρv. A standalone experiment has validated the simulation results of LAB. The new method can provide more accurate knowledge on light propagation in large liquid detectors, which is beneficial to the development of reconstruction for detectors.

The monochromatic laser source, typically using visible or near-infrared radiation, generates a highly focused beam of light. This light interacts with the molecules of the sample, scattering some of the light. Liquid and gaseous samples are usually tested in ordinary glass capillaries, while solids can be analyzed as powders packed in capillaries or as potassium...
