Dear Xinjie Zeng,
In order to use trapezoidal geometry for PET simulation, "PETscanner" should be used.
In addition, please use "genericRepeater" for the defining of the trapezoidal geometry with a full-ring PET configuration.
Best regards,
Han Gyu

Subject: [Gate-users] Attaching the sensitive detectors (SD) to trapezoid volume
Dear Gate-users,
I am defining a "general trapezoid" volume to the crystal and it works fine when I only look at the geometry. However, when I try to attach the sensitive detector to the crystal, the simulation breaks and fails. Please see below the set-up:

/gate/systems/cylindricalPET/crystal/attach   crystal
The Break message is attached. Nevertheless, when I define the geometry to "box", everything is fine. Does someone have experience with this or is there a bug in the trapezoid volume for attachCrystalSD? I have also tried "wedge" volume and the simulation breaks, too. Any suggestions would be highly appreciated!
Thank you!
