code does nothing. There appears to be nothing to track during the simulation.<br>
Everything works as expected when using e- particles or gamma but the ion doesnt<br>
function! I'm using Gate 5.0.0 and Geant 4.9.2<br>
<br>
Here is the code I use to define my source<br>
<br>
/gate/source/addSource Y90Source<br>

any help?<br>
<br>
