At the energies used in conventional MicroED experiments (80-300kV), and rates of electron exposure (0.1-20 e -/Å 2 ), incident electrons can break chemical bonds, gradually reducing the degree of ordering within a crystal. This induces the decay of Bragg reflection intensities, first at fine spatial frequencies. Many studies have measured and modeled these effects . Analogous effects in X-ray diffraction experiments have also been investigated in detail, given that beam-induced damage is considered one of the most persistent obstacles to structure determination in beam sensitive crystals, even at cryogenic temperatures . Likewise, the impact of electron beam-induced motion on crystallographic experiments is well studied. For example, in 1985, Henderson and Glaeser reported that beam-induced specimen motion was limiting high-resolution information in images of molecular crystals . However, anomalous changes in reflection intensities measured from catalase crystals have been observed by Bammes and coworkers at ultra-cold temperatures. In contrast to the anticipated pattern of decay in diffraction as a function of increased electron irradiation, non-monotonic changes in diffracted intensities were suggested to reflect a form of beam-induced specimen movement or charging . The consequences of this effect have remained largely unexplored.
