ABSTRACT
Enhancement of X-ray excited optical luminescence in a 100â
µm-thick diamond plate by introduction of defect states via electron beam irradiation and subsequent high-temperature annealing is demonstrated. The resulting X-ray transmission-mode scintillator features a linear response to incident photon flux in the range 7.6 × 108 to 1.26â
×â

photons s-1â
mm-2 for hard X-rays (15.9â
keV) using exposure times from 0.01 to 5â
s. These characteristics enable a real-time transmission-mode imaging of X-ray photon flux density without disruption of X-ray instrument operation.
