Figure 3
(a) Diagram of the vacuum chamber used to house the bent quartz monochromator in the experiments on the VUV bunker. The monochromator could be translated by a motorized control. The exit window was a disc of beryllium (Rosenbaum et al., 1971BB27). (b) The equatorial diffraction (A) from a piece of insect flight muscle obtained using the synchrotron radiation beam issuing from the monochromator. Also shown (B) is the equatorial diffraction from a similar sample obtained with a conventional X-ray source. The first strong reflection in A (seen only on the right side) is the 20 reflection (Bragg spacing 210 Å) from the hexagonal muscle lattice.
