Abstract

Sample damage by X-rays and other radiation limits the resolution of structural studies on non-repetitive and non-reproducible structures such as individual biomolecules or cells1. Cooling can slow sample deterioration, but cannot eliminate damage-induced sample movement during the time needed for conventional measurements1, 2. Analyses of the dynamics of damage formation3, 4, 5 suggest that the conventional damage barrier (about 200 X-ray photons per Å2 with X-rays of 12 keV energy or 1 Å wavelength2) may be extended at very high dose rates and ...
