Title: A neutron recoil-spectrometer for measuring yield and determining liner areal densities at the Z facility

Abstract

For this study, a proof-of-principle CR-39 based neutron-recoil-spectrometer was built and fielded on the Z facility. Data from this experiment match indium activation yields within a factor of 2 using simplified instrument response function (IRF) models. The data also demonstrates the need for neutron shielding in order to infer liner areal densities. A new shielded design has been developed. The spectrometer is expected to achieve signal-to-background greater than 2 for the down-scattered neutron signal and greater than 30 for the primary signal.

Phased plan for the implementation of the time-resolving magnetic recoil spectrometer on the National Ignition Facility (NIF)

Journal Article Kunimune, J. H. ; Gatu Johnson, M. ; Moore, A. S. ; ... - Review of Scientific Instruments

The time-resolving magnetic recoil spectrometer (MRSt) is a transformative diagnostic that will be used to measure the time-resolved neutron spectrum from an inertial confinement fusion implosion at the National Ignition Facility (NIF). It uses a CD foil on the outside of the hohlraum to convert fusion neutrons to recoil deuterons. An ion-optical system positioned outside the NIF target chamber energy-disperses and focuses forward-scattered deuterons. A pulse-dilation drift tube (PDDT) subsequently dilates, un-skews, and detects the signal. While the foil and ion-optical system have been designed, the PDDT requires more development before it can be implemented. Therefore, a phased plan ismore »« less

High-yield magnetic recoil neutron spectrometer on the National Ignition Facility for operation up to 60 MJ

Journal Article Gatu Johnson, M. ; Johnson, T. M. ; Lahmann, B. J. ; ... - Review of Scientific Instruments

We report that recent progress at the National Ignition Facility (NIF), with neutron yields of order 1 x 10¹⁷, places new constraints on diagnostics used to characterize implosion performance. The Magnetic Recoil neutron Spectrometer (MRS), which is routinely used to measure yield, ion temperature (T_ion), and down-scatter ratio (dsr), has been adapted to allow measurements of dsr up to 5 x 10¹⁷, and yield and T_ion up to 2 x 10¹⁸ in the near term with new data processing techniques and conversion foil solutions. This paper presents a solution for extending MRS operation up to a yield of 2 xmore »« less

Probing high areal-density cryogenic deuterium-tritium implosions using downscattered neutron spectra measured by the magnetic recoil spectrometer

Journal Article Frenje, J A ; Casey, D T ; Li, C K ; ... - Physics of Plasmas

For the first time high areal-density (rhoR) cryogenic deuterium-tritium (DT) implosions have been probed using downscattered neutron spectra measured with the magnetic recoil spectrometer (MRS) [J. A. Frenje et al., Rev. Sci. Instrum. 79, 10E502 (2008)], recently installed and commissioned on OMEGA [T. R. Boehly et al., Opt. Commun. 133, 495 (1997)]. The rhoR data obtained with the MRS have been essential for understanding how the fuel is assembled and for guiding the cryogenic program at the Laboratory for Laser Energetics (LLE) to rhoR values up to approx300 mg/cm{sup 2}. The rhoR data obtained from well-established charged particle spectrometry techniquesmore »« less

Inferring fuel areal density from secondary neutron yields in laser-driven magnetized liner inertial fusion

Journal Article Davies, J. R. ; Barnak, D. H. ; Betti, R. ; ... - Physics of Plasmas

A technique to infer the areal density ρR of compressed deuterium (D) in cylindrical implosions from the ratio of secondary D–T (deuterium–tritium) neutrons to primary D–D neutrons is described and evaluated. For ρR to be proportional to the ratio of D–T to D–D yield, the increase in the D–T fusion cross section with collisional slowing of the tritium must be small, requiring where TkeV is the electron temperature in keV. The technique is applied to results from laser-driven magnetized liner inertial fusion (MagLIF) targets on OMEGA, where ρR is certainly less than 4 mg/cm². OMEGA MagLIF targets do not achievemore »« less

The coincidence counting technique for orders of magnitude background reduction in data obtained with the magnetic recoil spectrometer at OMEGA and the NIF

Journal Article Casey, D T ; Frenje, J A ; Seguin, F H ; ... - Review of Scientific Instruments

A magnetic recoil spectrometer (MRS) has been built and successfully used at OMEGA for measurements of down-scattered neutrons (DS-n), from which an areal density in both warm-capsule and cryogenic-DT implosions have been inferred. Another MRS is currently being commissioned on the National Ignition Facility (NIF) for diagnosing low-yield tritium-hydrogen-deuterium implosions and high-yield DT implosions. As CR-39 detectors are used in the MRS, the principal sources of background are neutron-induced tracks and intrinsic tracks (defects in the CR-39). The coincidence counting technique was developed to reduce these types of background tracks to the required level for the DS-n measurements at OMEGAmore »« less
