Original Abstract

The inefficient collection of photons emitted from luminescent centres in a scintillation detector of electrons is a frequent cause of poor S(T)EM images, particularly in the BSE image mode. In such cases, edge guided signal (EGS) scintillation systems utilising a signal from the side of a scintillator, and having a complicated geometry, are often used. The best way of avoiding the light-guiding problems of these systems is Monte Carlo (MC) simulation optimisation for signal photon collection. Unfortunately, the previous code SCINTIL developed in our laboratory was built using an algorithm for rotationally symmetric systems where a function of one variable coordinate was used. Therefore, the extended code SCIUNI, intended for practically any geometry, has been written and its features are presented in this paper.
