Hi, I'm simulating a cylindrical scintillator wrapped by a perfectly diffuse reflector with no air gap. One face of the scintillator is set as a detection surface. My questions involve the reflector.
1. As I understand it, a perfectly diffuse reflector with no air gap between the scintillator and the reflector can be modeled by selecting the SetModel to be UNIFIED, the SetType to be dielectric_dielectric, and the SetFinish to be groundfrontpainted. Is this understanding correct? I'm referencing the attachment.
2. If the first statement is correct, would it therefore be redundant to add the following three reflector properties: specularspikeconstant(SS)=0, specularlobeconstant(SL)=0, and backscatterconstant(BS)=0, where lambertian (L) reflection is implicit (SS+SL+BS+L=1) to such a reflector configuration (namely: UNIFIED, dielectric_dielectric, groundfrontpainted)?
3. Out of curiosity, if I selected polishedfrontpainted instead of groundfrontpainted (with UNIFIED and dielectric_dielectric), in addition to setting SS=SL=BS=0 (L=1), would the reflector converge to Lambertian? I'm wondering if the reflector constants would override the specularspike reflection mode designated by polishedfrontpainted.
