论文摘要
我们通过电子束照射和随后的高温退火来表明100微米厚的钻石板中X射线激发光发光的增强。由此产生的X射线传输模式闪光灯对事件光子通量的线性响应在7.6 $ \ times $ \ times $ 10 $^8 $ to 1.26 $ \ times10^{12} $ photons/s/s/mm $ $^2 $用于硬X射线（15.9 keV）的线性使用时间为0.01到5 s。这些特性使X射线光子通量密度的实时传输模式成像，而不会破坏X射线仪器操作。
We demonstrate enhancement of X-ray excited optical luminescence in a 100-micron-thick diamond plate by introduction of defect states via electron beam irradiation and subsequent high-temperature annealing. The resulting X-ray transmission-mode scintillator features a linear response to incident photon flux in the range of 7.6$\times$10$^8$ to 1.26$\times10^{12}$ photons/s/mm$^2$ for hard X-rays (15.9 keV) using exposure times from 0.01 to 5 s. These characteristics enable a real-time transmission-mode imaging of X-ray photon flux density without disruption of X-ray instrument operation.
