<div class="moz-cite-prefix">Hi Pawel!<br>
<br>
I had the same problem. The thing is, you have to use a cold
source. I am attaching my source.mac and geometry.mac files, where
I define a geometrical entity that remains cold, and a source
which is larger than the geometrical cold area. <br>
<br>
The important statement is <br>
<br>
/gate/source/f18/gps/Forbid cold_area<br>
<br>
Of course, you can do the same with backtoback source rather than
e+ source.<br>
<br>
Cheers<br>
