description: DEAP-3600 (Dark Matter Experiment using Argon for Pulse shape discrimination) is a dark matter experiment using liquid argon as a target to detect dark matter's Weakly Interacting Massive Particles (WIMPs). This work is a contribution to the experiment, focused on optical processes inside the inner detector. In order to re-scale and calibrate complex optical system used in the apparatus, the distribution of external light is studied. This work includes a qualitative description of the optical model, data analysis of light reflection from liquid/gas argon boundary and an attempt of estimating the refractive index of wave-shifter material.

DEAP-3600 (Dark Matter Experiment using Argon for Pulse shapediscrimination) is a dark matter experiment focused on the direct detection of WIMPs (WeaklyInteracting Massive Particles). It is designed to detect the scintillation light, emitted in clodliquid argon after interacting with WIMPs. Therefore, precise optical characterization of theapparatus is crucial for accurate particle detection. This work is a cont…
