NIST only participates in the February and August reviews.
We measure neutron beam intensities for thermal and cold neutron beams, and develop methods to advance the accuracy of these measurements toward a goal of ±0.1 % for neutron beam intensities up to 109 neutrons/(cm2 sec). In addition, we make neutron fluence rate measurements for more complex reactor neutron fields and for fast neutron fields from accelerators and isotopic sources.
