After the success of the Inertial Confinement Fusion (ICF) ignition experiment, to figure out the microcosmic physics mechanism of the obstacles affecting repeated ignitions, the high-space-resolving and quantitative X-ray image of the obstacles is urgently needed. However, currently and internationally, it is very hard to realize both high-space-resolving and quantitative record and reading of X-ray images. Thus, this application has proposed a study on the new techniques of X-ray image recording and online reading. The atom-level image recording and the Radio-Photoluminescence (RPL) principles are used to solve the problem for the sub-micron space-resolving and quantitatively record of X-ray images. Quantitative X-ray image storage was realized based on the linear relationship between RPL intensity and X-ray irradiation time. X-ray image with a submicron spatial resolution of 0.7 μm was achieved, which could be stably stored without attenuation for more than 300 days. Additionally, heat treatment (400 °C for 2 h) could eliminate the influence of X-ray radiation on the Ag-doped phosphate glass (Ag-PG, one of RPL materials), and restore the state of the Ag-PG before X-ray irradiation, which allows the recyclability and reusability of the Ag-PG. Then, the spectrum response curve and a series of applications in ICF and for civil use are shown.
