I have created an elliptical mirror like this:
/// Ellipsoid G4RotationMatrix * toroidRot = new G4RotationMatrix; toroidRot->rotateY(pi/700); toroidRot->rotateZ(pi/900);
G4Ellipsoid * ellipsoidMirrorOutside = new G4Ellipsoid("farmirror Ellipsoid outside", farToroidalAxisRadius+farToroidalTubeRadius+mirrorThickness , farToroidalTubeRadius+mirrorThickness, farToroidalAxisRadius+ farToroidalTubeRadius+mirrorThickness, -100*cm, farToroidalAxisRadius+farToroidalTubeRadius+mirrorThickness);
G4Box* farMirrorBox2 = new G4Box("nearMirrorBox", xFarMirrorBox/2, yFarMirrorBox/2, farToroidalAxisRadius+farToroidalTubeRadius+mirrorThickness);
G4IntersectionSolid * outerPiece = new G4IntersectionSolid("3mm glass elliptical mirror", farMirrorBox2, ellipsoidMirrorOutside,toroidRot,G4ThreeVector(0,0,-farToroidalAxisRadius-farToroidalTubeRadius));
G4Ellipsoid * ellipsoidMirrorInside = new G4Ellipsoid("farmirror Ellipsoid inside", farToroidalAxisRadius+farToroidalTubeRadius, farToroidalTubeRadius, farToroidalAxisRadius+farToroidalTubeRadius);
G4SubtractionSolid * farMirrorGlassElliptical = new G4SubtractionSolid("Outside - Inside Ellipsoid", outerPiece , ellipsoidMirrorInside,toroidRot,G4ThreeVector(0,0,-farToroidalAxisRadius-farToroidalTubeRadius) );
It works ... ALMOST. That is it reflects properly and looks right, BUT the reflected photons do not interact and are killed once it reaches the edge of the box. Look here http://astro.temple.edu/~whit/badmirror.jpg .
When I swap the solid with a spherical mirror it works fine!! This mirror is constructed similarly:
// Temporary Far Spherical Mirror G4Sphere * farMirrorSphere = new G4Sphere("SphericalMirrorfar", farMirrorRadius, farMirrorRadius+mirrorThickness,0,360*deg,0,90*deg);
G4Box* farMirrorBox = new G4Box("farMirrorBox", xFarMirrorBox/2, yFarMirrorBox/2,farMirrorRadius+2*mirrorThickness);
G4IntersectionSolid * farMirrorGlass = new G4IntersectionSolid("3mm thick glass spherical mirror far", farMirrorBox, farMirrorSphere,0,G4ThreeVector(0,0,-farMirrorRadius));
Do you have any idea why this would happen????
Thanks in advance!
