Measurements of the ablation-front trajectory and low-mode nonuniformity in direct-drive implosions using x-ray self-emission shadowgraphy

作者： D.T.Michel A.K.Davis W.Armstrong R.bahr R.Epstein V.N.goncharov M.Hohenberger I.V.Igumenshchev R.Jungquist D.D.Meyerhofer P.b.Radha T.C.Sangster C.Sorce D.H.Froula Laboratory for Laser Energetics University of Rochester

Self-emission x-ray shadowgraphy provides a method to measure the ablation-front trajectory and low-mode nonuniformity of a target imploded by directly illuminating a fusion capsule with laser beams. The technique uses time-resolved images of soft x-rays(>1 ke V) emitted from the coronal plasma of the target imaged onto an x-ray framing camera to determine the position of the ablation front. Methods used to accurately measure the ablation-front radius(δ R= ±1.15 μm), image-to-image timing(δ( t)= ±2.5 ps) and absolute timing(δt= ±10 ps) are *** averaging of the images provides an average radius measurement of δ( Rav)= ±0.15 μm and an error in velocity of δV / V= ±3%. This technique was applied on the Omega Laser Facility [boehly et al., Opt. Commun. 133, 495(1997)] and the National Ignition Facility [Campbell and Hogan, Plasma Phys. Control. Fusion 41, b39(1999)].

＜正＞Along with the mastering of millimeter（MM） and submillimeter（SbMM） spectral ranges for the purposes of spectroscopy,the problem of construction of different filtering systems is becoming increasingly *** analogy to optical units,various MM-SbMM high-,low- and band-pass filters can be developed using metallic grids,meshes or dielectric layers as ***,the characterization of these constructions by measuring their electrodynamic properties is not so easy and trivial for conventional spectroscopic techniques.
