Actually I meant a Gaussian shape of the beam not the Gaussian energy distribution. But I looked at the PBS and I think it, in addition to a Gaussian energy distribution, has a "Gaussian shape" capability too.

But it seems there isn't such a capability in gate! As I found out, one can just select the type (Point, Plane, Volume) and then the shape (rectangular, ellipse, cylinder, ...) of the source. And the gate would sample uniformly over the source. What about if we need a non-uniform (Gaussian) sampling of particles? Does anybody have a clue on this problem?</span></font><font face="Helvetica" color="black"><span style="font-family:Helvetica;color:black;"></span></font></div> </div> <div id="yiv2343542029yui_3_16_0_1_1438167084342_11700"> <div class="yiv2343542029MsoNormal" style="background:white;"><font face="Times New Roman" color="black" size="3"><span style="font-size:12.0pt;color:black;">I remember that in MCNP code, that's possible easily.</span></font><font face="Helvetica" color="black"><span style="font-family:Helvetica;color:black;"></span></font></div> </div> <div id="yiv2343542029yui_3_16_0_1_1438167084342_11712"> <div class="yiv2343542029MsoNormal" style="background:white;"><font face="Helvetica" color="black" size="3"><span style="font-size:12.0pt;font-family:Helvetica;color:black;"> </span></font></div> </div> <div id="yiv2343542029yui_3_16_0_1_1438167084342_11713"> <div class="yiv2343542029MsoNormal" style="background:white;"><font face="Times New Roman" color="black" size="3"><span style="font-size:12.0pt;color:black;">Thanks in advance</span></font><font face="Helvetica" color="black"><span style="font-family:Helvetica;color:black;"></span></font></div> </div> <div id="yiv2343542029yui_3_16_0_1_1438167084342_11720"> <div class="yiv2343542029MsoNormal" style="background:white;"><font face="Times New Roman" color="black" size="3"><span style="font-size:12.0pt;color:black;">Somayeh</span></font><font face="Helvetica" color="black"><span style="font-family:Helvetica;color:black;"></span></font></div> </div> <div id="yiv2343542029yui_3_16_0_1_1438167084342_11379"> <div class="yiv2343542029MsoNormal" style="background:white;"><font face="Helvetica" color="black" size="3"><span style="font-size:12.0pt;font-family:Helvetica;color:black;"> </span></font></div> </div> </div> </div> </div> <div class="yiv2343542029MsoNormal" style="margin-bottom:12.0pt;background:white;"><font face="Helvetica" color="black" size="3"><span style="font-size:12.0pt;font-family:Helvetica;color:black;"> </span></font></div> </div> </div> <div> <div class="yiv2343542029MsoNormal" style="margin-bottom:12.0pt;background:white;"><font face="Times New Roman" color="black" size="3"><span style="font-size:12.0pt;color:black;"> </span></font></div> </div> </div></div> </div> </div></div><br clear="none"><br clear="none"></div> </div> </div> </div></div></body></html>
