Abstract
A scintillator type radiation detector package is provided including a scintillation crystal directly coupled to the window of a photomultiplier. A scintillator package is also provided having a longer life at wellbore temperature with minimal deterioration of a hygroscopic scintillation crystal(s). Direct optical coupling of the scintillator to the photomultiplier reduces the amount of light lost at coupling interfaces and improved detection resolution over the conventional structures having separate packages for crystal and photomultiplier.
Claims20
An integrated scintillation detector comprising:
- a scintillation crystal and a photomultiplier having a faceplate, said photomultiplier being at least partially contained within a scintillator housing, wherein the scintillator crystal is directly attached to the photomultiplier faceplate without an optical coupling pad.
