Multiple source location with same isotope


I am working on the shielding of a room that contains several drums with Co-60, as the souce located within several drums, I wish to have multiple BEAMPOS, is it possible to do this with FLUKA?

Thanks you for your kinds!


Dear @tzhang,

I can see 3 possible ways forward:

1-You can run separate simulations defining a cobalt source in a different location and then sum up the results of the simulations. In this case you have to add the results with the correct weight.

2-You could try to use the SPOTBEAM card, that allows you to define different primary beams coming from different positions.

3-You could write your own source routine using the source_newgen.f on which you can find several info both on this forum and on the slides from the last course.
