[Gate-users] source with an Annulus shape

[Carlos Montes]

Hi Sophie,
 
An Annulus is a "plane" source NOT a "volume" source.  If you want a "volume annulus" you have to modify source code to extend it to a fixed "z" (like in a cylinder definition) and recompile, of course.  In the definition of "plane annulus" z = 0.
 
Hope this helps,

  I try to define a source with an Annulus shape (a cylinder with a hole inside, in order to place another source inside).
Gate seems to understand the command lines (any insults when the macro is interpreting) but the program is not able to
generate any event from this source.

Error: Volume Shape Doesnt Exist

Has anyone already use this shape for a source volume?

thanks in advance for your help,

Sophie

Objet : [Gate-users] CPET system problem? 


Hello,
Is the "CPET" system definition broken is GATE ? 
I found another entry in Gate-Users-Talk reporting the same problem 
(by kmitev in Jan 2007), without any response.

After I (attempt to)  attach the crystal as in 
"/gate/systems/CPET/crystal/attach crystal" 
I get a seg-fault.

Has anyone solved this problem? 
Thanks much,

Ahmet
