Description
Cryogenic scintillator experiments are typically difficult to optimise by trial and
error due to the difficulty of performing repetitive experiments at low temperatures.
Monte-Carlo simulations are therefore an attractive option for optimising the light
collection from cryogenic scintillators. The talk presents two of the most commonly
used packages for the simulation of scintillators: Geant4 and Litrani. A difficulty
in performing simulations is determining the input parameters such as the bulk
properties (the intrinsic light yield, the scattering and absorption coefficients)
and the surface properties. The MCRIM technique for determining the bulk properties
is presented as well as AFM measurements of CaWO4 crystals in order to estimate
surface properties. Results of simulations with CaWO4 are presented and compared with
some published results.
