INSTRUMENTATION PACKAGE AND INTEGRATED RADIATION DETECTOR

摘要

An instrumentation package in broad terms includes a t least one substantially cylindrical instrumentation component; a substantially cylindrical shield surrounding the instrumentation component, the shield having a diameter less than a standard predetermined diameter; and a sizing sleeve around the sleeve, thereby increasing the diameter of the sleeve to the standard predetermined diameter. A nuclear detector package is also disclosed that includes a substantially cylindrical crystal element; a photomultiplier tube arranged coaxially with the crystal element; an optical coupler sandwiched between one end of the crystal element and an adjacent end of the photomultiplier tube; the crystal element, optical coupler and photomultiplier tube hermetically sealed within a cylindrical shield; and a flexible support sleeve extending exteriorly along the crystal element and the photomultiplier tube and radially inside the cylindrical shield.
