A photon transport model code for use in scintillation detectors

A project to measure quantum spin correlations of relativistic electron pairs in Møller scattering

“…It is expected that the requirement of a coincidence in two counters (as explained above) will eliminate most of this background as well as beam scattering events. The response of the scintillation counters is simulated in parallel using both Geant4, as well as the FLUKA [30] and PHOTRACK [31] packages, the latter dedicated to light collection in the scintillator-lightguide assembly.…”

On the necessity of light transport simulation in scintillators

“…The light transport simulation is based on the geometrical optics with the following main steps [10]:…”

“…The light transport code, PHOTRACK, was written and its first results were published in 2004 [10]. The wavelength-dependent version of the code was introduced in 2006 [11].…”

A sensitivity analysis approach to optical parameters of scintillation detectors

“…The whole process usually contains: (1) photon generation, (2) attenuation, (3) intersection with scintillator/light guide wall, (4) reflection, and (5) detection. The above steps were used in PHOTRACK code and the light collection results of different surface coverings compared with those of Schoelermann and Klein [5], who studied a large (5.1 cm diameter, 5.1 cm high) scintillator, showed a good overall agreement [1].…”

“…Monte Carlo modelling of light transport in scintillators provides important information including the light collection efficiency, detection resolution, number of photon interactions, photon transit time, and timing resolution [1][2][3][4][5]. The whole process usually contains: (1) photon generation, (2) attenuation, (3) intersection with scintillator/light guide wall, (4) reflection, and (5) detection.…”
