Detector Configuration For Well-Logging Tool

In a logging tool, a plurality of detectors (such as, e.g., a plurality of scintillation detector assemblies each including a scintillation crystal and associated photomultiplier tube) may be individually pressure-encased and arranged about a longitudinal axis of the tool, leaving a flow space betwe...

description	In a logging tool, a plurality of detectors (such as, e.g., a plurality of scintillation detector assemblies each including a scintillation crystal and associated photomultiplier tube) may be individually pressure-encased and arranged about a longitudinal axis of the tool, leaving a flow space between the detectors for the flow of drilling mud or other fluid through the tool. In some embodiments, this arrangement allows increasing the volume of detector material (e.g., scintillation crystal) without compromising the total cross-sectional area of the flow space (or increasing the total cross-section area without reducing the volume of detector material), compared, e.g., with tool configurations in which a single pressure case encloses the detectors. Additional apparatus, systems, and methods are disclosed.
