Painted reflector

Hi Fluka experts,
How can I design a painted reflector (for scintillation detector) in Fluka? Can you send me an example if you have one?


simulating particle interaction with paint in a reasonably accurate way is a very very difficult problem. You can try to use the user routine FRGHNS to a certain extent but there are limitations which can be important, depending on the use case - see
