<font face="Liberation Serif, serif">Dear
GATE community,</font><br>
<br>
<font face="Liberation Serif, serif">I
am simulating a proton beam with a “PencilBeam” source type in
GATE v.8.2. For the proton beam I set an activity value and an
acquisition time.</font><br>
<font face="Liberation Serif, serif">In
the verbose output, I have observed that all the primary particles
(protons) are being generated at the same timestamp T0. </font>
<br>
<br>
<font face="Liberation Serif, serif">Despite
the fact that I can check in the verbose output that the code is
computing the time of the
beginning of the next event (with the function
GateVSource::GetNextTime), it seems that this time value is not
added when the next
event begins. Therefore, all protons are being thrown at T0.</font><br>
<br>
<font face="Liberation Serif, serif">This
behavior is not present in a gps source type.</font><br>
<br>

anyone </font><font style="font-size: 12pt" size="3">know if
there is a way to have a time distribution of the primary
particles in a Pencil Beam source</font><font style="font-size:
