I want to simulate a tracking pixel detector, with a geometry consisting of several concentric cylinders.
I tried this set up according to the following sequence 1) parametrisation along the radial direction 2) replication along phi 3) and replication along z direction.
Everything is working fine except for that I am not able to obtain the position of the pixel which receives the hit.
I use the following code to get the position of the pixel which recieves the hit.
G4StepPoint *preStepPoint = aStep->GetPreStepPoint(); G4TouchableHandle touchable = preStepPoint->GetTouchableHandle(); G4ThreeVector origin(0.0,0.0,0.0); G4ThreeVector pixelPos = touchable->GetHistory()->GetTopTransform().Inverse().TransformPoint(origin);
But this gives me only the Z cordinate of the pixel and the X and Y coordinates are 0.
Can anyone tell me a solution, or an alternate approach
