Technological experience in the construction of silicon tracking detectors for space experiments

Silicon trackers technology, developed in the last century for accelerator based experiments, is currently used in several space-borne astro-particle experiments. The challenge is not only in the design and construction of the detector itself, but also in fulfilling the special requirements imposed by the launch process and the hostile running environment in space. In particular, the silicon trackers for DAMPE and LIMADOU experiments designed, assembled and tested under INFN Perugia leadership, have been successfully launched in space: DAMPE in December 2015 and LIMADOU in February 2018 and they are currently taking data. In this contribution, we report on the design and assembly of both trackers and the results from the construction.
