Figure 2
Distortion of the capillary figure owing to gravity. Calculations from the theory of flexure of simple beams (Appendix A) show that proper mounting is an important factor if capillary figure errors are to be reduced to a level appropriate for next-generation X-ray sources. The y-axis represents deviations from the ideal centerline of the optic. Support points are shown as triangles, with open triangles corresponding to the dashed line. The solid line supported at the solid triangles represents an optimally supported optic which minimizes overall figure error. |
