A neutron probe is designed for use in nuclear reactors whose neutron flux is to be measured. The probe is embedded in an envelope consisting of an inner layer of a moderator of large diffusion length, a central layer of a reflector of small diffusion length, and an outer layer of a strong neutron absorber. The envelope bears directly against a gamma absorber plate between the reactor vessel and the biological shield. The advantage of the neutron probe is that disturbing iniluences such as impinging gamma radiation and coupling with other probes are obviated. Various configurations of the probe for use with fast neutrons, other probes, etc., are described. (D.L.C.)
