Description
In this work, the algorithm for simulating scintillation is examined, particularly the one used in the Geant4 toolkit. Being widely adopted in experimental particle physics, Geant4 became the standard for detector simulation, including those based on noble elements, which in turn are used due to their scintillation properties. Geant4 algorithms for scintillation physics are 20 years old and have seen just a couple of updates during this time. Here, we examine the current algorithm and its shortcomings, including percent-level systematic biases that we all need to be aware of. We also exemplify a particular situation where some materials can produce a significant bottleneck during a simulation's runtime. Finally, we propose changes that address these issues and perform a comparative analysis with the current algorithm.
