| Abstract |
Over time X-Ray mirrors are demanded for better focusing, closer to sample refocusing, spot size as well as better beam uniformity at sample position. Based on the experience of ALBA Phase I beam lines a new alter-native design of a mirror bender* is proposed. The system includes two main functionalities: the mirror bender mechanism and mirror figure error correc-tion. Both mechanisms are based on the introduction of a force constrain on the mirror surface instead of a geometrical one. As being based on a force mechanism they could reach high resolution and especially for the correctors which can achieve nanometre resolution. The correctors are designed to provide high force stability in the mirror side, eliminating the crosstalk between bending and figure correction, and minimizing the sensitivity to drifts. With such controlled deformation of the mirror substrate it is possible to obtain the desired surface figure not only to correct mirror figure errors but also to adapt it to the incident wavefront, thus becoming adaptive system. The mechanical solutions are presented which are able to correct mirror surfaces with a resolution of 1 nm reaching slope errors below 100 nrad.
