The scintillation test case is part of the verification

activity for the Geant4 optical physics library ([Ciabattoni et al.,

2024](https://ui.adsabs.harvard.edu/abs/2024SPIE13093E..7YC/abstract)

), performed in preparation to benchmark the simulation of

the COSI anti-coincidence system ([Ciabattoni et al., 2025](https://ui.adsabs.harvard.edu/abs/2025ExA....60....9C/abstract)). All

user-defined files required to run the simulation are provided as

part of the example application.

The simulation involves irradiation with X-ray photons of a

scintillation detector and the consequent generation of optical

light within the crystal. The mass model consists

of a trapezoidal CsI(Tl) block measuring 198 mm in length,

20 mm in height, and with widths of 93 mm (top) and 70 mm

(bottom). The crystal is mounted within an aluminium hous-

ing and wrapped in two layers of Teflon followed by two layers

of aluminium foil, enhancing internal reflection of optical pho-

tons. The aluminium casing presents an open window (55 mm

in diameter) that allows optical coupling between the CsI and a

PMT via an optical pad. In BoGEMMS-HPC, the CsI block and

the aluminium housing are imported as CAD models, while the

remaining components are constructed using standard Geant4

geometry classes. The physics used in the simulation includes

the standard Livermore polarised physics, along with the scin-

tillation physics to model optical photon generation. The simu-

lation consists of irradiating CsI(Tl) scintillator blocks with 122

keV photons. The energy deposited in the crystal is converted

into optical photons (54 photons/keV), a fraction of which is

subsequently absorbed by the PMT
