Cylindrical source definition

Description

Dear Fluka experts:

I’m trying to define my beam as source on the surface of a cylinder with a radius of 10 cm. The idea is that this cylinder emits photons only outwards from its surface. I’ve created a bin card to verify the source, but the results are as if the source were a point source. Could you help me?

Thank you in advance!!!

Dear Jilberto,

Thanks for your question. I have had a look at your input file and the source routine — you have gotten already quite close! However, you forgot to include a SOURCE card, which is required to call the source routine. Without this card, the simulation falls back to the pencil beam source, as you have been experiencing.

You can find more explanation on Slide 27 of the lecture from the FLUKA beginner course last year:

I hope this helps and don’t hesitate to come back in case anything is left unclear.

Cheers,
Barbara
