Simulation of radiation damage to a two-dimensional crystal formed of images of a flea (from Robert Hooke's Micrographia). Each `hit' corresponds to the application of a local Gaussian blur at a randomly selected location (Supplementary Fig. S7). (a) Four unit cells (each 1024 × 512 pixels) of the undamaged two-dimensional crystal (left) and the square of the FFT amplitude, proportional to the diffracted intensity, of a 16 × 16 cell crystal (right). (b) After receiving a large number of hits (>>1 per pixel) the electron density has been blurred and the high-resolution (large q) diffraction peaks have faded out. A full video of the evolution of the crystal and its diffraction pattern with dose is given in Supplementary Movies S1 and S2.
