[Gate-users] Ion particle simulation Issue

[sd48 at buffalo.edu]

Hi All,
       I'am facing the following problem with regards to the simulation of 
an "ion particle" isotope.

My simulation crashes with the following "crash messages" when my source 
isotope is an "ion particle".

		However, if i retain all the other environmental settings the same and 
change the source isotope(in the source.mac) into a different type of 
particle (eg: a positron), the simulation goes thru' properly. Below are 
the macro files that i have used for simulation :

               I'am using the gate_v3.0.0 version for the simulation. Could 
anyone kindly provide some hints for this issue. Thank you.
