Effect of dose rate on type II damage in hydrated DiPOPE at 50% w/w buffer (150 mM NaCl, 20 mM TES, pH 7.4) and 305.5 K. The HII phase intensity on the ordinate axis corresponds to the integrated diffraction signal in the (10) reflection of the HII phase that appears on a background of the Lα phase. The dose rate and the elapsed time (in s) at the end of each exposure are indicated. Measurements were made at the ESRF on beamline ID2 (12.5 keV, maximum flux 6.3 × 1011 photons s−1, attenuation achieved by using metal foils) under conditions of continuous sample irradiation. Sample preparation is similar to the protocol described by Cherezov et al. (2000BB3).
