PPPS-2013: Modeling scintillator thickness for optimal light output for given input photon energy

One of the many paramount questions raised by x-ray radiographers, who utilize flash radiographic sources and scintillators (i.e., BGO or LSO) to relay the x-ray to visible light converted transmission radiographs to a recording imaging system, is determining the optimal thickness for a scintillator to yield its maximum light output for a given input photon energy. This is especially true given a potentially cost prohibited method of first procuring a variety of scintillator samples and empirically testing for the output performance in situ for a variety of scintillator thicknesses. Other motivations may be to maximize signal to noise (SNR) for a light starved, optical fast, emittance limited imaging systems.
