Footprints due to beam damage in a fully hydrated lipid sample housed in a 1 mm-diameter quartz capillary. The sample was photographed using front illumination with a dark background. Damaged areas (footprints) are translucent and appear as dark spots in the photograph. This experiment was performed in May 2000 at the ESRF on beamline ID2 [12.5 keV, 6.3 × 1011 photons s−1, 30 Mrad dose (for largest footprints) at 640 krad s−1]. The sample was DPPC at 50% w/w water and 298 K.
