Abstract

Abstract

This article reviews the latest developments of high time- and space-resolving diagnostic technique for laser-driven inertial confinement fusion (ICF) in China. Focusing on the needs of hot spot diagnosis with temporal resolution better than 10 ps, spatial resolution better than 10 μm, and energy range of 10−30 keV, we introduce recent progress in optical, X-ray, and nuclear diagnostics, as well as computational imaging. In optical section, we introduce two diagnostics based on the pump detection technique: all-optical scanning, with temporal resolution up to 200 fs, and all-optical framing, with temporal and spatial resolution up to 5 ps and 5 μm respectively. Since the main components are optical, these systems have great potentials to be applied in the strong electromagnetic, ionizing environment of future ICF research. In X-ray section, we introduce a recently developed high-resolution kirkpatrick-Baez (KB) microscope, which adopts the STTS (S and T represent sagittal and tangential directions respectively) configuration and improves the spatial resolution to 3 μm, meeting the current requirements. Besides, we also discuss a developing technology—the drift tube technology, with temporal resolution up to 10 ps. In nuclear section, we mainly introduce the high-resolution recording system of the neutron imaging, with spatial resolution up to 20−25 μm, as well as the progress in the corresponding aiming technique. In addition, we introduce computational imaging, which is a brand new branch attracting growing attention in ICF field. We also emphasize the three dimensional light field imaging technique and compressed ultrafast photography (CUP) technique, and propose their possible applications in ICF field.
