How to depict angular distribution

Hello dear experts,
I would like to depict the angular distribution of electron beam after passing through a target. If possible, please explain which card do I need to activate and configure?

Best regards

Dear Zohrab,

The USRYIELD scores a double-differential particle yield. By selecting “polar angle” as first quantity and integrating the result over the whole range of the second quantity, you can get the angular distribution of the beam. Notice that, the angular distribution is calculated with respect to a fixed direction.

You can also use USRBIN card to score the distribution of electrons in a given position after the target, in case you want to extract the beam profile.

For more details regarding how to set the cards, please check the FLUKA manual.

Kind regards,
Marta
