Hi Pawel,
<div><br>
</div>
<div>the simplest way is to define a phantom of the same size als</div>
<div>the source volume and define it as PhantomSD:</div>
<div><br>
</div>
<div>/gate/source_vol/attachPhantomSD</div>
<div><br>
</div>
<div>Then you can define the type of material in the same way as you </div>
<div>would do for any phantom. In Gate_v7.1 you can make sure to have</div>
<div>all relevant processes being switched on by using:</div>
<div><br>
</div>
<div>/gate/physics/addPhysicsList emstandard_opt3</div>
<div><br>
</div>
<div>Hope this helps!</div>
<div><br>
</div>
<div>Kind regards,</div>
<div><br>
</div>
<div>Uwe</div>
