[Gate-users] Object interfering with the simulation - Ring repeater bug

[Stefania Cazzato]

Hi Gate users,I'm trying to simulate a microPET scanner as shown in the figure, using the PETscanner system. To correctly put the sensitive detectors (trapezoid shapes, in green) inside the PETscanner (grey cylinder along Z axis) I had to introduce another cylinder, called PETscanner1 (grey cylinder along X axis). However this object interfere with the simulation, 'deleting' the events that should be detected by the portion of the trapezoids inside PETscanner1 (looking at the Coincidences, there is a circular 'hole' of exactly the same dimensions of PETscanner1) . Do you know how to solve this problem? I tried to create the detectors using only PETscanner, but (as I read on a previous comment) it seems there is a problem with the ring repeater, and my efforts were useless.Thanks in advance!Stefania
