Title: PHOTOMULTIPLER-BASED NEUTRON DETECTOR
Abstract:
A neutron detector is provided which may include a neutron converting layer, and a scintillator layer adjacent the neutron converting layer. The neutron detector may further include a photomultiplier adjacent the scintillator layer. By way of example, the neutron detector may be used in a well logging apparatus to determine a neutron flux incident upon the neutron converting layer, and thereby determine the neutron porosity of a geological formation around a wellbore.
