Abstract
A unitized scintillation detector, employing a scintillation element and a photomultiplier tube housed within inner and outer housings for protection against shock, and a scintillation shock assembly. The scintillation element is encased within potting material, which is further enclosed within a rigid shield. A reflective coating or reflective tape may be used to optimize light impulse transmission from the element to the photomultiplier. The element is further protected from shock by an elastomeric boot disposed around the shield and within the housing. In addition, elastomeric material cushions the element on one end and a spring system protects the other end. The spring system is pre-loaded against the shield, not the element. Dual windows interfacing the scintillation element and photomultiplier tube at the other end of the element create an hermetic seal. In another embodiment, a single optical window may be used. The photomultiplier tube is encased within an elastomer with outwardly directed projections. The photomultiplier tube is protected from radial and axial shock as well as thermal excursions.
