I have a question concerning type FLOOD of BEAMPOS card. It says that this produce a uniform and isotropic fluence within the sphere. The value of the produced fluence will be 1/(pi R^2) cm-2. This is true and that was exactly what I needed. But can anyone share the algorithm of such implementation? How it was implemented in details. Maybe some papers discussing this algorithm. I have a few suggestions, but I’d like to know exactly how it was done here.
