Abstract
A scintillation detector providing a photomultiplier tube mounting system capable of withstanding substantial vibration and the like without damage to the photomultiplier tube. The mounting system provides a resonant frequency substantially above the frequency of the vibration normally encountered to prevent amplification of the vibration. The photomultiplier tube is mounted within a support tube with a thin layer of elastomeric material. The support tube is in turn mounted in a light-tight tube by spaced elastomeric rings having a relatively high spring rate. The support tube is provided with openings which render the support tube radially resilient so that thermal expansion of the elastomeric material between the support tube and the photomultiplier tube does not result in high compressive loads on such tube. Further, the elastomeric material can elastically flow into the openings in the support tube to relieve compressive stresses which would otherwise occur.
