The slowed neutrons been deflected back to the tool are counted by detectors. Since the tool responds primarily to the hydrogen content of the formation, the measurement is scaled in porosity units. Both epithermal and thermal neutrons can be measured depending on the detector design. The tool uses two thermal detectors for a borehole-compensated thermal neutron measurement. The tool can be combined with other 530-Series tools or subs through TCT and NEC.
