Figure 3
Four diffraction patterns from a series of 23 consecutiveframes (0.05° per frame, 0.083° between adjacent images; see text for details) collected at 200 keV with a Medipix2 Quad detector (512 × 512 pixels). The crystal was orthorhombic lysozyme, maximum resolution ∼1.8 Å. The frame on the far right is after 30 s of data collection and shows the degradation in signal arising from beam damage. Each frame was exposed to between 0.05 and 0.1 e− Å2 per second. |
