Description

Dear Fluka/Flair experts,

I want to create a photon fan beam shape for my job.

So, do I need to edit a “source_newgen.f” file?

Or, actually, can I create it simply through the Flair?

I really appreciate any help you can provide.

Thanks in advance.

Please describe the issue. In case of reporting a bug, please provide step-by-step instructions for reproducing the error.

Input files

I do not have an input file.

Please upload all relevant files. (FLUKA input file, Flair project file, user routines, and data files)

Dear Jittapan,

maybe this post will help you:

Asymmetrical flat cone beam

Hello Ihor, you have two options to do that: using a source routine, you can set all properties of the beam particles. See some of these relevant forum posts: link1, and link2 (for the older source routine). if you would rather not use the source routine, you can use the SPOTBEAM to create a beam spots with more fine-grained properties than you would in a BEAM card, including different divergences in x and y. You then have to use a SPECSOUR card to indicate that you have a single BEAMSPOT…

Cheers,
David
