Neutron interactions with matter provides unique tools for investigating a range of characteristic and properties. Experiment facilities at the NETL reactor include in-core and ex-core irradiation sites supporting various nuclear analytic techniques, and a full suite of gamma spectroscopic analysis systems.
In-core facilities are used principally to produce radioactive isotopes. The isotopes are analyzed to determine concentrations of a large number of elements in a process called neutron activation analysis, or are deployed in research programs. There is a range of nuclear characteristics available at the NETL's multiple sample delivery systems, providing flexibility for a broad set of applications.

Ex-core irradiation sites have been developed to provide capabilities for neutron depth profiling, prompt gamma activation analysis, and neutron radiography. A cold source expands the potential of these techniques using low energy neutrons. A positron source is currently in development.
Neutron Depth Profiling is the measurement of distribution of a select set of elements in samples such as boron in transistors, hydrogen in batteries.
Prompt Gamma Activation Analysis expands the range of measurement of elemental concentration in samples to some elements that cannot be analyzed using decay gammas.
Neutron Radiography is similar to x-ray techniques, but the characteristics of neutron interaction with matter provides capabilities for extracting different kinds of information from a sample.

The NETL facilities utilize a set of gamma detectors that include a Compton suppression system, gamma gamma coincidence based analysis, and several more traditional high efficiency detection systems for the measurement and assay of radioactive materials.
