Measurements of the Tm 169 (n,2n) Tm 168 cross section from threshold to 15 MeV


Journal Article

© 2017 American Physical Society. Measurements of the Tm169(n,2n)Tm168 cross section have been performed via the activation technique at 13 energies between 8.5 and 15.0 MeV. The purpose of this comprehensive data set is to provide an alternative diagnostic tool for obtaining subtle information on the neutron energy distribution produced in inertial confinement deuterium-tritium fusion experiments at the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory. The Tm169(n,2n)Tm168 reaction not only provides the primary 14-MeV neutron fluence, but also the important down-scattered neutron fluence, the latter providing information on the density achieved in the deuterium-tritium plasma during a laser shot.
