A high spatial resolution X-ray image detector is designed and costructed. The detector consists of a scintillator, light microscopy optics and charge-coupled device (CCD). The scintillator has a mosaic form with 4x5 mm2area and consists of 1x1x0.3 mm3elements fabricated from Y3Al5O12:Ce (YAG:Ce) and Gd3Ga5O12:Ce (GGG:Ce) bulk crystals. Using "Zemax" program the mirror-lens microscopic optical system is calculated and constructed. The Philips FTF4052M CCD has 4008(H) x 5344(V) active pixels (pixel size 9um) with sensitive area 36.072 mm x 48.096 mm. The detector has been characterized using visible-light images. X-ray images from a mosaic of scintillation crystals were also obtained. The estimated spatial resolution of the detector is 1 m. |
