However, when I try to attach the sensitive detector to the crystal, the simulation breaks and fails. Please see below the set-up:</div><div><br>/gate/systems/cylindricalPET/crystal/attach crystal<br>/gate/crystal/attachCrystalSD<br clear="all"><div> </div><div>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.
