Description
The study and the development of innovative imaging detectors represent a crucial element in the field of X-ray imaging, mainly to overcome some of the limits of the standard ones. In this work an overview of the main results obtained during the study and the development of imaging detectors based on optically active point defects produced by X radiation in lithium fluoride (LiF) crystals and films will be presented. The LiF detectors are based on optical reading of visible photoluminescence produced by aggregated colour centres (CCs), locally produced by X radiation, and among their peculiarities, noteworthy ones are their very high intrinsic spatial resolution across a large field of view, wide dynamic range and versatility.
LiF-based detectors for extreme ultraviolet radiation, soft and hard X-rays are currently under investigation for imaging applications with laboratory radiation sources, e.g. laser-driven plasma sources and conventional X-ray tubes, as well as large-scale facilities, e.g. synchrotrons and free-electron lasers. The achieved results confirm that LiF-based detectors are powerful and versatile tools for X-ray imaging.
