Description
Dear FLUKA Experts,
Greetings to all of you. I am currently confronted with a shielding problem related to multi - beam point radiation and would like to seek your valuable advice. The problem is described as follows: in one input file, I have defined three beam target points using the SPECSOUR, SPOTBEAM, SPOTPOS and SPOTDIR cards. The energies and corresponding beam intensities of these three beams are different. How should I set the SPOTWEIGHT values so that the calculated results can be scaled to the actual dose equivalent generated by the three beams hitting the targets with only a single NORM coefficient?
At present, I take the beam intensity of Target Point 1 as the reference, setting its SPOTWEIGHT to 1, and the SPOTWEIGHT values of the other two target points to the ratios of their respective beam intensities to that of Target Point 1. Based on this setting, can I convert the calculated results to the actual values simply by multiplying them by the beam intensity of Target Point 1?
Furthermore, for the scenario involving multiple beam target points, what value should the Sampling parameter in the SPECSOUR card be set to in order to yield results that are closer to the actual experimental outcomes?(Note: All the multiple beams exist simultaneously.)
