Enhancement of X‐ray excited optical luminescence in a 100 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 × 10 8 to 1.26 × 10 12 photons s −1 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.
