[gate-users] Cold Phantoms in GATE

Hi everybody,

I am trying to simulate a cold phantom using Gate, and there is 
something not very clear to me:

    Assume that the phantom that I want is just a couple of cylinders, a 
small one (lets call it B) placed inside
    the big one (called A). Now I want to place an activity source in 
the region A-B.

    Is it possible to achieve this by using the "confine" option? I.e., 
if I define the physical cylinder A, and then
    the phyisical cylinder B as a "daughter" of A, and then I create my 
cylindrical activity source and confine it
    to the physical volume A, should I obtained the desired result?

    If not, does anybody know of some other way of defining cold phantom?

Thanks in advance!

Best regards,
