ABSTRACT:
Set forth in the accompanying disclosure is an apparatus 10 and method broadly useful for monitoring the concentration of a hydrogenous component within a given sample or space. The specific apparatus disclosed is directed to monitoring steam quality within a steam conduit 12. A fast neutron source 22 is positioned proximate a conduit 12. A moderating element 32 is situated intermediate the source 22 and conduit 12 for softening the neutron spectrum incident to the conduit 12. Two neutron detectors 36 are positioned at opposite sides of the conduit 12, each being spaced an equal radial distance from the source 22. Means 42 is provided for establishing from the rate of neutron detection and certain other physical properties of the sample data concerning the concentration or disposition of a hydrogenous component of the sample. The source 22, detectors 36, and conduit 12 are surrounded by a neutron reflector 20 of neutron moderating material.
