Patent ID: 7629584

Claim:
A system for measuring ionizing radiation comprising a scintillator that comprises: a first assembly of at least two rod-shaped scintillator elements, which can be optically coupled to one another via their opposed face ends; a second assembly of interconnectable sheath elements, wherein said first assembly of scintillator elements is coaxially enclosed by said second assembly of interconnectable sheath elements; and at least two face-end window elements, wherein said first and second assemblies and said face end window elements form at least two scintillator modules each composed of one respective scintillator element having a length dimension, one respective sheath element having a length dimension parallel to the length dimension of said one respective scintillator element and two of said face-end window elements, each said module being optically and mechanically connectable to additional scintillator modules, wherein at least one of said scintillator modules further comprises at least one spring element interposed between said scintillator element and said sheath element of said at least one of said scintillator modules, said spring element being disposed parallel to the length dimensions of said scintillator element and said sheath element to permit a relative displacement between said scintillator element and said sheath element.
