Abstract

There are many surface models that describe the comportment of photons when they hit a rough dielectric surface. However, the existing models did not give very good results when used to predict the photoelectron yields produced by BGO crystals. As those models use a slope distribution to describe the roughness of the surfaces, we have designed a new model using a height distribution rather than a slope distribution. MOSAIC uses a Delaunay triangulation to build a static surface. The staticity and the height variation of the surface should correct most of the problems that were not taken in account by a slope variation model such as shading and multiple reflections.
