[Gate-users] source with an Annulus shape

[Samuel BURG]

Hi,

here's how to build a cylinder with a hole :

/gate/source/addSource SrcMainInsert
/gate/source/SrcMainInsert/gps/particle gamma
/gate/source/SrcMainInsert/setActivity 100000. Bq
/gate/source/SrcMainInsert/gps/energy 140. keV
/gate/source/SrcMainInsert/setForcedHalfLife 21636 s
/gate/source/SrcMainInsert/gps/type Volume
/gate/source/SrcMainInsert/gps/shape Cylinder
/gate/source/SrcMainInsert/gps/halfz   17.0 mm
/gate/source/SrcMainInsert/gps/radius  22.5 mm
/gate/source/SrcMainInsert/gps/radius0 21.5 mm
/gate/source/SrcMainInsert/gps/centre 0. 0. -10.75 mm
/gate/source/SrcMainInsert/gps/angtype iso
# small beam: usefull for testing  geometry
/gate/source/SrcMainInsert/gps/mintheta  89.5 deg
/gate/source/SrcMainInsert/gps/maxtheta  90.5 deg
/gate/source/SrcMainInsert/gps/minphi    89.5 deg
/gate/source/SrcMainInsert/gps/maxphi    90.5 deg
/gate/source/SrcMainInsert/gps/posrot1 1. 0. 0.
/gate/source/SrcMainInsert/gps/posrot2 0. 0. 1.

and the screen capt of the root postprocessing in the file c1.pdf

Best regards,

Samuel

Objet : [Gate-users] source with an Annulus shape

Bonjour,  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
