Paper Abstract

The ray-tracing is power-full technique for the design and the prediction of the performances of an X-Ray optics. When working with traditional monolithic shells, the possible design is quite constrained once fixed the focal length, the dimensions of the module and the field of view: simulations are used to determine the effective area and optical performances of realized mandrels and shells, taking into account for example profile errors or roundness measurements. Instead, when the optics are segmented into two separate reflective surface, integration errors with respect to position and rotation of the plates play an important role and may be also used to recover intrinsic plate errors. Moreover when the mirror segments are produced by replica, it is possible to optimize the design of a module to be cost effective. In this paper we present the design of a prototype module for the International X-ray Observatory (IXO) resulting from a proprietary ray tracing code. The module will be composed by 20 plate pairs all made with the same integration forming mandrel. The degradation of optical performances of the prototype are expected to be limited to few arc seconds.
