A Novel Neutron Recoil Spectrometer Concept Utilizing Heavy-Ion Recoils and Time- and Spatially-Resolved Sensor
This thesis describes a heavy-ion recoil neutron spectrometer as an alternative to existing magnetic proton recoil neutron spectrometers for inertial confinement fusion experiments. Whereas existing designs elastically scatter neutrons o↵ protons or deuterons, which are then magnetically analyzed …

Shielding design for the time-resolving Magnetic Recoil Spectrometer (MRSt) on the National Ignition Facility (NIF)
… toward this goal. The time-resolving Magnetic Recoil Spectrometer (MRSt) aims to provide time-resolved measurements of the neutron spectrum, to determine time evolution of ion temperature, areal density, and neutron yield, at a time resolution of 20ps and an energy resolution of 100 keV. This …

Characterization and optimization of signal and background for the time-resolving magnetic recoil spectrometer on the National Ignition Facility
… be obtained with the next-generation Magnetic Recoil Spectrometer (MRSt) that will measure the neutron spectrum (12-16 MeV) with high accuracy (~5%), unprecedented energy resolution (~100 keV) and, for the first time ever, time resolution (~20 ps). To successfully implement the MRSt on the NIF …

Diagnosing inertial confinement fusion implosions at OMEGA and the NIF Using novel neutron spectrometry
A novel neutron spectrometer, called the Magnetic Recoil Spectrometer (MRS), was designed, built, and implemented on the OMEGA laser facility and the National Ignition Facility (NIF) to measure the neutron spectra from inertial confinement fusion (ICF) implosions. Using the MRS, the down-scattered …

Using fusion-product spectroscopy to diagnose inertial confinement fusion implosions and study stopping power on OMEGA, the NIF, and Z
… implosion performance on the Z. Traditional nToF spectrometers face additional challenges at the Z facility due to large scattering sources from the machine and long neutron burn widths. For this reason, a CR-39 based neutron-recoil spectrometer has been developed for measuring the DD spectrum at …
