X-Ray Pore Optics Technologies and Their Application in Space Telescopes

Figure 19

An early concept for assembling MPO sectors into an X-ray optics unit. The support structure is made of Titanium and must provide the correct and stable alignment of the sectors, while protecting them from thermal and mechanical loads. Three s-shaped flexures at the optic mount absorb mechanical loads, which would otherwise pass directly to the optic from the optical bench; they also provide a possible mount point for a filter. MPO sectors can be individually removed and replaced by unscrewing the bolts to the pads. The diameter of the optics is 200 mm.
