[gate-users] cold phantom...

[Sebastien JAN]

Hello,

You can find this message from Jean-Marc Viera on the GATE-USERS talk 
section in our wib site :

Hi Joung,
Derenzo phantom can be described with the quadrant repeater as the 
example hereby describing active rods. (see GateUsers : chap 4... for 
the geometry)
The cold material is described with the first macro Geometry.mac, filled 
with air material,
and the source with Source.mac
One solution to describe the warm  Derenzo with cold rods "could" be to 
first define an active cylinder (mother volume), 
add some cold rods as daughters volume, then confine the source to the 
mother volume. I didn't try to describe this Derenzo version, but one
 could easily observe the decay positions/hits, eg. with root, to check 
if the geometry is OK.
Best regards,  Jean-Marc
