Development of an X‐ray imaging system to prevent scintillator degradation for white synchrotron radiation

Abstract

The high flux of the white X‐ray beams from third‐generation synchrotron light sources can significantly benefit the development of high‐speed X‐ray imaging, but can also bring technical challenges to existing X‐ray imaging systems. One prevalent problem is that the image quality deteriorates because of dust particles accumulating on the scintillator screen during exposure to intense X‐ray radiation. Here, this problem has been solved by embedding the scintillator in a flowing inert‐gas environment. It is also shown that the detector maintains the quality of the captured images even after days of X‐ray exposure. This modification is cost‐efficient and easy to implement. Representative examples of applications using the X‐ray imaging system are also provided, including fast tomography and multimodal phase‐contrast imaging for biomedical and geological samples.
