Figure 5
Diagram of the remotely controlled low-angle diffraction camera in bunker 2. The mirrors were housed in a helium perspex case fitted with mylar windows. The curved quartz monochromator was mounted in air. All other intervening beam paths were through lead-covered vacuum tubes. Note the primary slits (aperture 1) and the guard slits (aperture 2). The shape and composition of the slits were important for reducing parasitic scatter. A monitoring TV camera ran along a parallel optical bench (not shown).
