We describe the ongoing development of TNT, the T-region Neutron Tagger. As a way of overcoming the problem of normalization in neutron scattering experiments, we are developing a facility to tag the production of neutrons on an event-by-event basis. The neutrons are produced using the reaction p+d→n+2p with a 200 MeV circulating proton beam incident on a deuterium gas jet target in the Indiana Cooler. The tagging of a neutron is accomplished via the detection of the two low energy recoil protons in an array of double-sided silicon strip detectors. A tagged neutron beam makes possible absolute neutron cross section measurements, and the first experiment that will be done using this tagged neutron facility is a measurement of the np backscattering cross section. Some other possible experiments using tagged neutrons are also presented. © 2000 American Institute of Physics.
