摘要：

Soft X-ray (0.28 and 1.74 keV) images produced by the focusing action of a planar, square-pore microchannel plate (MCP) are described. These images contain for the first time the three-component cruxiform structure expected from the studies of Angel [Astrophys. J. 233 (1979) 364] and Chapman et al. [Rev. Sci. Instr. 62 (1991) 1542], and so indicate a high degree of geometric regularity within and between the approximately 46000 active channels in the MCP structure. The angular resolution of the central ''true'' focus is approximately 10 arc min FWHM.
