Abstract
A scintillation detector capable of withstanding high shock and/or high temperatures, comprises a scintillation crystal, a casing for the crystal, and a shock absorbing boot interposed between the crystal and the casing. The boot is characterized by a plurality of radially outwardly directed protrusions for engaging the casing. The protrusions define therebetween unfilled spaces to provide room into which the boot may expand at high temperatures. The protrusions may be longitudinally or radially extending ribs and the ribs may be generally rectangular or triangular in cross section. A reflector surrounds the crystal and preferably is in the form of a thin porous sheet of polytetrafluoroethylene (PTFE) wrapped tightly around the crystal. The boot preferably has a substantially continuous cylindrical interior surface for engaging the thin porous PTFE sheet to avoid high pressure concentrations.
