Hi all,
I want to count the primary particles that succeed in passing through my sensitive detector, but I get a number greater than the number of initial particles !
As you will see in this tracking output ;

the 2nd step says that the next volume is the WorldVolume while this primary particle will change direction in step 3, and will propagate the whole step 4 in my sensitive detector before leaving it in step 5.
So it counts twice.
.
What can I do to eliminate these steps? (I used the IsLastStepInVolume() condition but I get the same result, as the next volume information remains the same.)
Is there a better way to count particles at a volume boundary ?
.
Thank you !
