The goal of the Neutron Induced Fission Fragment Tracking Experiment (NIFFTE) is to measure fission cross sections with unprecedented precision. The tracking capabilities of this device allow for the full reconstruction of charged particles produced by neutron beam induced fission from a thin central target. The wealth of information gained from this approach allowed cross section systematics...
Neutron-induced reactions are important to our understanding of fundamental nuclear physics as well as nuclear applications. Due to their impact on a wide range of nuclear physics applications, it has become important to better understand the probability such reactions occur and try to minimize their uncertainties. In particular, there is a need for precision neutron-induced fission cross...
Uranium-233 has played an important role in critical assembly experiments going back to the 50's and 60's, including experiments from the Falstaff Program. The thorium fuel cycle has been proposed as an alternative to the uranium fuel cycle due to its reduced amount of transuranium elements. $^{232}$Th is more abundant in nature than uranium, and decays in the thorium fuel cycle into the...
The multiplicity and energy spectra of prompt fission neutrons from photofission of
235U, 238U, and 239Pu were measured with 13.5 MeV incident photons.
Measurements were taken with a 1 m flight path and a relatively sparse array of
BC501A/EJ301 scintillators such that multiple scattering effects between detectors were
minimal. The targets were mounted in ionization chambers to tag fission...
