在本文中，我们描述了在“点对点”聚焦模式下使用平面方孔微孔微通道获得的X射线图像。现在已经测量了氢还原伽利略MCP(29毫米有效直径；大约44,000个有效通道)的全场照明的角分辨率为5角分fwm。其次，利用原子力显微镜、扫描电子显微镜和光学显微镜对方孔微通道板进行了初步的测量。最后，我们扩展了我们对球形凹陷、圆孔飞利浦MCPs作为X射线扩束器的研究。
In the present paper, we describe X-ray images obtained using planar, square pore MCPs in `point-to-point' focusing mode. Angular resolution of 5 arcminutes fwhm has now been measured for full-field illumination of a hydrogen-reduced Galileo MCP (29 mm active diameter; approximately 44,000 active channels). Secondly, we report some preliminary metrology of square-pore microchannel plates using atomic force, scanning electron and optical microscopies. Finally, we extend our study of spherically-slumped, round-pore Philips MCPs operated as X-ray `beam expanders'.
