Abstract
A high-temperature well logging instrument of the scintillation detector type includes a plastic scintillation element susceptible to softening and deformation at high operating temperatures. To maintain the shape of the scintillation element at such high temperatures, a metal retaining cup holds the scintillation element in its original shape. The retaining cup with the scintillation element inside is capped at its open end by a silicon rubber pad that is transparent to photons generated by the scintillation element in response to detected radiation. A biasing spring holds the end face of a photomultiplier tube against the silicon rubber pad so as to sandwich the pad between the photomultiplier tube and the open end of the metal retaining cup. Such a configuration maintains excellent optical coupling between the scintillation element and photomultiplier tube during high-temperature well logging.
