- Abstract
This Paper presents the $\mu$ROSI X-Ray Telescope currently under development at the Max - Planck Institute of Extraterrestial Physics (MPE). As primary payload on board of the south-tyrolean amateur satellite "Max Vallier", $\mu$ROSI is designed to perform an all-sky survey similar to the ROSAT mission. Although both, the spatial resolution and the collecting area are much less compared with ROSAT,spectral resolution of the silicone drift chamber detector (SDD) selected for $\mu$ROSI is excellent, matching that of XMM-Newton or Chandra. A never done before survey of the x-ray emission from earth's geo-corona is a further scientific goal. Max Vallier is developed and launched in cooperation with OHB. µRosi consists of a 12 shell Wolter-1 mirror, the silicone drift chamber detector, control electronics, a thermal control system for the SDD, and an optical bench structure to support and align all components. We describe these various subsystems of the telescope and their current development status. Special emphasis is given to the latest analysis and design work on the structural configuration and the already completed testing of the structural qualification model. We also adress the challenging process of superpolishing the mirror mandrells, which is currently underway and report on the final alignment and characterisation campaign in MPE's x-ray testing facilities.
