一种新型的条纹软x射线成像仪被设计用于位于劳伦斯利弗莫尔国家实验室的国家点火装置的高能量密度（HED）物理实验。该条纹成像仪使用狭缝孔径、镍镜的单浅角度反射和软x射线滤波，当与NIF的x射线条纹相机之一耦合时，可以记录4倍放大的x射线源一维图像，空间分辨率小于90 μm。所产生的能带通取决于所使用的滤光片材料；在第一次资格射击中，使用钒和钛上银滤波器分别栅极光子能量范围约为300-510 eV和200-400 eV。鼻口的双通道版本可用于高达1毫米的x射线源，单通道可用于高达3毫米的较大源。单通道和双通道变体都已通过石英线和HED物理目标射击。
A new streaked soft x-ray imager has been designed for use on high energy-density (HED) physics experiments at the National Ignition Facility based at the Lawrence Livermore National Laboratory. This streaked imager uses a slit aperture, single shallow angle reflection from a nickel mirror, and soft x-ray filtering to, when coupled to one of the NIF's x-ray streak cameras, record a 4× magnification, one-dimensional image of an x-ray source with a spatial resolution of less than 90 μm. The energy band pass produced depends upon the filter material used; for the first qualification shots, vanadium and silver-on-titanium filters were used to gate on photon energy ranges of approximately 300-510 eV and 200-400 eV, respectively. A two-channel version of the snout is available for x-ray sources up to 1 mm and a single-channel is available for larger sources up to 3 mm. Both the one and two-channel variants have been qualified on quartz wire and HED physics target shots.
