Assessment of radiation damage. (a) A series of SAXS patterns recorded from a single spot of sample while it was irradiated continually for 700 s. The cumulative exposure time is indicated at the bottom of each pattern. Note that the initially clear feature of the hexagonal lattice is gradually lost. These patterns were obtained from a flight muscle fiber from a giant cranefly, Ctenacroscelis mikado. (b) The time course of the change of integrated intensity of the 2,0 reflection (open circles) and its intensity variation along its circumference expressed as standard deviation (filled circles, its full scale is 0.7 of the averaged intensity). The sudden drop of intensity after 400 s and its sudden recovery after 600 s may be due to beam instability.
