The National Diagnostic Working Group (NDWG) has led the effort to fully exploit the major inertial confinement fusion/high-energy density facilities in the US with the best available diagnostics. These diagnostics provide key data used to falsify early theories for ignition and suggest new theories, recently leading to an experiment that exceeds the Lawson condition required for ignition. The factors contributing to the success of the NDWG, collaboration and scope evolution, and the methods of accomplishment of the NDWG are discussed in this Review. Examples of collaborations in neutron and gamma spectroscopy, x-ray and neutron imaging, x-ray spectroscopy, and deep-ultraviolet Thomson scattering are given. An abbreviated history of the multi-decade collaborations and the present semiformal management framework is given together with the latest National Diagnostic Plan.

In order to improve the two-dimensional imaging diagnostic accuracy of inertial confinement fusion (ICF) experiment, a calibration method of the dynamic spatial resolution of X-ray framing image-converter (XFIC) is proposed. When an object with straight edge function is projected onto the photocathode of XFIC as an input, edge spread function can be obtained by recording an image of the XFIC output. The first derivative of the edge spread function produces the line spread function (LSF). Then the modulation transfer function (MTF) of the system can be worked out by Fourier transform of the LSF. Therefore, the spatial resolution can be deduced. According to this theory, the spatial resolution of XFIC can be obtained. Based on SG-Ⅱ laser facility, the calibrating X-ray source is generated by 8 bundled lasers bombarding the target. High-Z knife-edge is irradiated by the X-ray and imaged on the photocathode of XFIC, and then a dynamic image is obtained as the system works in the gating mode. By handling the dynamic image, the LSF of XFIC is given by analyzing the edge image. Then the MTF of the camera can be indicated by the Fourier transform of the LSF. When the MTF is 0.1, the corresponding spatial resolution of the imaging system is 20 lp/mm. According to the dynamic spatial resolution theory of framing image-converter, the extreme spatial resolution is 22.8 lp/mm. The calibration result agrees with the theoretical results. By contrast, the static spatial resolution of the same X-ray framing image-converter calibrated by the traditional method is presented here. The calibrated static spatial resolution is 22 lp/mm, a little higher than the dynamic one. During the two-dimensional imaging diagnosis, the X-ray framing image-converter works in the dynamic gating mode, thus the calibrated dynamic spatial resolution can be more truthful to reflect its imaging diagnosis ability.
