Compact Kirkpatrick–Baez microscope mirrors for imaging laser-plasma x-ray emission

Compact Kirkpatrick-Baez microscope mirror components for use in imaging laser-plasma x-ray emission have been manufactured, coated, and tested. A single mirror pair has dimensions of 14 × 7 × 9 mm and a best resolution of ~5 μm. The mirrors are coated with Ir providing a useful energy range of 2-8 keV when operated at a grazing angle of 0.7°. The mirrors can be circularly arranged to provide 16 images of the target emission a configuration best suited for use in combination with a custom framing camera [F. J. Marshall, J. A. Oertel, and P. J. Walsh, Rev. Sci. Instrum. 75, 4045 (2004)]. An alternative arrangement of the mirrors would allow alignment of the images with a four-strip framing camera such as described in D. K. Bradley et al. [Rev. Sci. Instrum. 66, 716 (1995)].
