Paper Abstract

The following procedure is used to evaluate modifications of the optical performances of the JET-X telescope mirror shells (MS) due to manufacturing, integration tolerancing, gravity, and thermal gradients: analysis of the deformed shape of the MS by means of the ADINA finite element (FE) code, and optical performance analysis by means of a ray tracing code (RTC) for the Wolter 1 telescope directly interfaced with the FE code output. For the different conditions analyzed, half power radius, encircled energy, and spot diagrams are computed. Numerical analyses are performed for the single mirror shells and for the whole mirror module. The numerical models used are described, and the main features of the RTC and the relevant results are discussed.
