Patent
·
OSTI ID:6694151
A new and improved gain stabilization system for radioactivity well logging apparatus is of the type having a scintillation crystal and optically coupled photomultiplier in a sonde to detect radiation in the borehole and formation elements in response to neutron bombardment. The gain stabilization system includes a light emitting diode driven by a pulser and furnishing scintillations to the photomultiplier, resulting in a stabilization pulse which is furnished to electronic circuitry at the surface for stabilization purposes.
