Run few events with /tracking/verbose 2 may help you.

[NickyMH]

I tried but it doesn’t work

[maire]

It works in example Activation ! (as in any other examples …)
What did you change ?

[NickyMH]

I changed the material and the type of beam

Thanks for your help I already solved it, in the mac file the energy was in millielectrovolts, but I need megaelectrovolts
