摘要：

The X-ray detection efficiency of charge coupled devices (CCDs) is dependent on the thickness of the active depletion layer in the silicon, typically less than 40 mu m and limited by the purity of available epitaxial substrates. For X-ray imaging, therefore. The CCD detection efficiency drops sharply above 8 keV. In this Letter, we show that, using a novel illumination geometry, CCDs can detect high energy (up to 100 keV) X-rays with reasonable efficiency and good energy resolution. A novel 2-D imaging hard X-ray detector based on this geometry is discussed.
