Calculated Time Correlated Neutron Induced Radiations In A Sandstone Formation PDF Download

The following signals from the proposed Borehole Neutron Diagnostic Probe, which uses the associated particle technique for timing and spatial resolution of the events produced by 14 MeV neutrons, in a 4.5 inch borehole in a sandstone formation were investigated: (1) The inelastic gamma-ray spectrum by a gamma ray spectrometer whose signal input is correlated with the time emission of a 14 MeV neutron into the formation. (2) The capture gamma-ray spectrum measured by a gamma ray spectrometer whose signal input is not correlated with neutron emission and has the time correlated events gated out. (3) The time dependence of the inelastic gamma-ray signal. (4) The time dependence of the capture gamma-ray signal. (5) The measured coincidence signal from the detection of prompt gamma rays and prompt neutrons from fission.
