Description
Accurate and fast optical photon simulation is critical for optimizing the geometry design of next-generation liquid noble and scintillator-based detectors, where light collection efficiency directly drives energy and position resolution. While standard tools like Geant4 are robust, they are often computationally expensive for high-photon-yield applications. In this talk, we present our development of a workflow based on Chroma, a GPU-based ray-tracing framework that accelerates optical photon propagation by orders of magnitude compared to CPU-based methods. To demonstrate its physical accuracy, we showcase validation results from the Light-only Liquid Xenon (LoLX) experiment. We validate the simulation by comparing its outputs with experimental data, specifically highlighting the energy and position reconstruction of events from an external gamma calibration source. This open-source package aims to provide a user-friendly, scalable, and high-speed simulation solution for future liquid noble detectors or R&D experiments that require detailed optical characterization.
