Abstract

The probe lowered into the bore hole has a source of ionising radiation and detectors with transducers producing pulses in accordance with detected reflected radiation. A time division multiplex system using a memory matrix of buffer capacitors between the switches in the write and read address stages (multiplexer and demultiplexer) is used and reshaped pulse signals fed via an analogue digital converted to an analyzer on the surface.
