Scheme of two flat parallel coaxial MCPs for focusing of the X-ray beam; d1 is the distance between the two MCPs and d2 the distance between the detector and second MCP. 1 – primary radiation; 2 – first MCP; 3 (inset) – image of the capillary structure of both MCPs; 4 – second MCP; 5 – 2D detector of radiation; 6 (insert) – focal spot profile; 7 (insert) – focal spot cross-section. |
