Laboratory Experiments Using a Pulsed Neutron Source

Laboratory experiments using pulsed neutron techniques are valuable for giving physical interpretation to elements of nuclear reactor theory encountered in the classroom. Three experiments were selected from those reported in the literature to illustrate different pulsed neutron measurements. In one case diffusion properties of a sample are measured by varying the geometry of the sample. In another the absorption cross section of a solute is measured by varying the sample without changing its geometry. A third experiment illustrates the use of a pulsed neutron source in reactivity measurements.
