[Gate-users] ion source simulation

[Pedro Guerra]

Hi all,
I am trying to simulate  a I125 line source,
using an ion source as described by the text below.

So far, I´ve been unable to get a single hit in my detectors (i know though
that the scanner description is fine, as I've been using it with with gammas)
and I wonder whether something may be wrong in the script of some
flag needs to be activated.

Could someone give a hint of what may be the cause of my error?

best regards,
