An ionization chamber for fission fragment analysis
Fission fragments play a pivotal role in understanding the entire nuclear fission process, and their effects are widespread to all applications involving nuclear fission: reactor design and maintenance, waste removal, active and passive integration of nuclear materials, simulations, and the …

A time-of-flight spectrometer for fission fragment identification
Fission fragment and product inventories play a key role in many areas of nuclear science from simulation of fissioning systems to diagnostics for optimal reactor operation and waste disposal. New experimental data are needed to further reduce the uncertainty in the current standard data as well as …

Ionization Chamber Design, Development, and Testing for the UNM Fission Fragment Spectrometer
Fission fragment and product inventories play an important role in many areas of nuclear science from simulation of fissioning systems to active and passive interrogation of nuclear materials. The characteristic properties of fission fragment distributions are currently lacking in experimental …

Fission fragment mass distributions and total kinetic energy release of 235-uranium and 238-uranium in neutron-induced fission at intermediate and fast neutron energies LA-UR-15-28829
… with increasing incident neutron energy for fission of $^{235}$U and $^{238}$U. Although fission was discovered over seventy-five years ago, open questions remain about the physics of the fission process. The energy of the incident neutron, $E_n$, changes the division of energy release in the …

NUCLEAR DEFORMATION IN FISSION FRAGMENTS STUDIED WITH NOVEL IMPLEMENTATIONS OF DOPPLER SHIFT LIFETIME MEASUREMENT TECHNIQUES
… measurement of lifetimes of excited states in fission fragments. This method has been applied to the first set of data taken with an active fis- sion target coupled to an array of germanium detectors. The nuclei have been populated via neutron-induced fission on 235 U, dissolved in a liquid …

Fission dynamics in a microscopic theory
… functional theory (TDDFT) to investigate the fission dynamics of atomic nucleus, which is still one of the most complicated problem in nuclear physics and a full microscopic interpretation is still missing. The establishment of the time-dependent superfluid local density approximation (TDSLDA) …

The effect of radiation damage by fission fragments on the structural stability and dissolution of the UO2 fuel matrix
… of this work was to study the separate effect of fission fragment damage on the structural integrity and matrix dissolution of uranium dioxide in water. Radiation damage similar to fission damage was created by irradiating bulk undoped and doped ‘SIMFUEL’ disks of UO2, undoped bulk CeO2 and thin …

A High-Resolution Time-of-Flight Spectrometer for Fission Fragments and Ion Beams
… of exotic neutron-rich nu- clei. Nuclear fission is a suitable method of producing such nuclei with masses from 60 - 150. Neutron-rich nuclei close to the r-process path can be produced via photo-fission at the Rossendorf superconducting linear accelerator of high brilliance and low …
