Hi<br><br>I'm trying to simulate a Y-90 source, and would like to see the bremsstrahlung produced from the beta.
<br>The problem is that there
are
absolutely nothing in my gateHits.dat and gateSingles.dat files. In
fact, the same problem occur everytime I define source as ion particle.<br><br>Below are part of my macro. <br>Or do you think that it is due to other problem?<br><br>and, am I correct to use an effective half-life of Y-90 (37828 s) instead of the physical half life (
2.67 d) ?<br><br><div>#--------#<br># SOURCE #<br>#--------#<br><br>/gate/source/addSource beta<br><br>/gate/source/beta/gps/particle ion
