Chen, J. R. Rygg, S. Volkmer, D. Casey, F. H. Séguin, J. A. Frenje, C. K. Li, and R. D. Petrasso Plasma Science and Fusion Center Massachusetts Institute of Technology J. Delettrez, V. Yu. Glebov, S. Regan, S. Roberts, T. Sangster, and V. Smalyuk Laboratory for Laser Energetics University of Rochester CollaboratorsSlide3: Motivation Dual nuclear reactions provide additional information about the target implosion Dual spectra and yields allow for more rigorous benchmarking of simulations Analysis of perceived discrepancies may shed physical insight into the implosion dynamicsSlide4: The Charged Particle Spectrometer allows us to measure spectra and yields on OMEGA The magnet spectrometer directs particles onto appropriately filtered CR-39 detectors.Slide5: Shot 39792 DT(20)SiO2[3] Track Diameter filtering (also contrast, eccentricity) In thin glass DT implosions, CPS can measure the yield and spectra of the DD-p in the DT noiseSlide6: We can derive an Tion from Doppler broadening σ in keV, C = 1510 for DD-p nTOF provides us with DT neutron yields and Tion Tion can be derived from Doppler broadening.Slide7: CPS provides us with DD-p yields in thin glassSlide8: Reaction ratios fall slightly outside of expected ranges Data Range Slide9: Future Work Examine YOC and compare to DHe3 YOC discrepancies Since DD-p do not escape CH surrogate capsules, we must study the DD-n with nTOF. We currently cannot see the DD-n in the DT-n background. Thin Glass DD-p yields and spectra will allow us to validate DD neutron data when techniques are developed.
