[mcstas-users] Effective region of the source

[Federico M. Bertalot]

Hello,

i am trying to know the effective region of the source. In other words, 
each time a neutron reachs the detector i want to know, which region of 
the source it came from.

I think that one possible solution is to create a source component that 
stores the starting position of each neutron in a new variable. Then, 
the detector reads this new variable. Maybe this can be done using 
store_neutron() also, but i dont know how to read the trace-history.

if you know a better solution, please tell me.

Thank you very much.

Federico.
