Two-dimensional monochromatic x-ray imaging of laser-produced plasmas

A slitted crystal spectrograph has been used to produce two-dimensional, spatially resolved, monochromatic images of laser-irradiated targets. The technique is described, and examples are presented for comparison with corresponding pinhole photographs. Resolution along and tranverse to the dispersion are determined by the crystal rocking angle and geometry of the spectrograph, respectively. One important application of this technique would be to radiograph hot, compressed targets, since the slitted spectrograph behaves as a filtered rectangular pinhole
