Configuration of an indirectly illuminated X-ray area detector for XPCS. The detector consists of (1) a beryllium entrance window, (2) an input phosphor screen on a fiber-optic plate, (3) an image intensifier [a photocathode and a microchannel plate (MCP)], (4) two optical relay lenses, and (5) an image sensor. An X-ray image on the phosphor screen is intensified and focused on the image sensor. The CCD and CMOS image sensors are easily exchanged by using a Philips mount. |
