Angular distribution of secondary particles

Particles, Track, Event, Run and Biasing

Hi,

I am simulating a proton beam hitting a concrete box and want to be able to detect the angular distribution of the neutrons emerging from my concrete box. I have managed to determine how many neutrons are emerging and got a histogram of that but I can’t seem to find any examples of where the angular distribution of secondary particles has been plotted in the example files?

Thanks

Louise

Hi,

I had a look at that example and when i tried to run it with concrete to detect neutral particles, nothing was detected.
I then tried to incorporate it into the NeutronSource example to see the angular distribution but i am getting a lot of errors.
Are there any other resources to help ?
It is part of my masters project and I have only started using geant4 in june

Thanks,

Louise
