[Gate-users] Annulus cylinder source

[Pawe Kowalski]

I would like to ask if it is possible to create in GATE 7 annulus cylinder source.
Teoretically it should be possible using following example commands:
/gate/source/addSource cylinder gps/gate/source/cylinder/gps/type Volume/gate/source/cylinder/gps/shape Cylinder /gate/source/cylinder/gps/radius0 9.5 cm/gate/source/cylinder/gps/radius 10.5 cm /gate/source/cylinder/gps/halfz 5. cm /gate/source/cylinder/gps/pos/centre 0. 0. 0. mm/gate/source/cylinder/setActivity 1000000 Bq/gate/source/cylinder/setType backtoback/gate/source/cylinder/gps/particle gamma/gate/source/cylinder/gps/ene/mono 511. keV/gate/source/cylinder/gps/angtype iso/gate/source/list
Unfortunatelly, in results it looks like it was not annulus cylinder but full cylinder. The problem was also mentioned here: http://thread.gmane.org/gmane.comp.science.opengate.user/3109
Best regards, Paweł Kowalski
