Direct X-ray imaging model

This camera system is designed for directmeasurement of X-rays. Four types of CCD elements are available for selection. In ordinary imaging of X-rays, an instrument such as a scintillator is used,and the X-rays are converted to visible light before imaging is dine withthe CCD. Because the CCD is made of silicon, however, the inherent characteristicsof the CCD itself enable direct imaging of X-rays. For instance, a characteristics.X-ray of 5.9 KeV is emitted from the F55 of radioactive isotope. This X-rayproduces approximetry 1,620 electrons in silicon. For this reason, CCD scan be used as X-ray sensors with extremely high sensitivity.
When imaging X-rays, the CCD must be selected based on the incident energy. Particularly if the incident energy is 1 to 2 KeV or less, it is necessaryto use a back-thinned illuminated CCD. With ordinary CCDs, poly silicongate are mounted on side of the CCD on which the incident light falls. totransport charges , so the X-rays is absorbed by these electrodes and detectionis less efficient.
back-thinned illuminated CCDs, which have no electrodes on the incidentsurface, can be used effstively in such applications.
