[Gate-users] Complete tracking ("collision tape") of the primaries

[Geron Bindseil]

Hi Till,

You can obtain the position of the final location of the hit in the
sensitive detector by using the root output. It is one of the data
fields, along with the position of the original decay or particle
generation.

However, if you need access to the full history for each primary, I'm
not sure if this is an output possibility built into GATE, but I know
that it is possible to write your own Actor that has access to the
complete tracking history and you can write out the data you need to a
file that way. You'll need to write it in c++, but you can follow the
format of the preexisting Actor classes.

Kind Regards,
Geron

Unfortunately the "hits" output only scores the number of events in the phantom (attached to phantomSD), but doesn't provide the necessary coordinates of the event. As my primaries are X-rays, I am looking to extract the position of each individual Compton or Rayleigh interaction.
