15 July 2008 Future high-resolution x-ray telescope technologies: prototype fabrication methods and finite element analysis

The Smart X-ray Optics (SXO) project is a UK based consortium consisting of several institutions investigating the application of active/adaptive optics to both large and small scale grazing incidence x-ray optics. University College London presents work relating to the large scale x-ray optics that is geared towards the next generation of x-ray space telescopes. It is proposed that through the addition of piezoelectric actuators, an active x-ray telescope with a resolution better than that currently achieved (e.g. Chandra 0.5") could be realised. An immediate aim of the SXO project is to produce an operational active ellipsoidal segment prototype, with point-to- point focusing and with the intention of being tested at the University of Leicester's x-ray beam source. Work relating to the fabrication of the prototype will be presented, including shell replication via a nickel sulphamate electroforming process, piezoelectric actuators and prototype assembly and operation. Results from finite element analysis modelling will be discussed; these relate primarily to gravitational distortion effects and the plating tank electrostatics.
