Abstract

A number of key astrophysical questions are still unanswered due to the unsatisfactory sensitivity of the present instrumentation in the hard X-/soft Gamma-ray energy band. Such lack could be filled in the near future using Laue lenses which will enable the focusing power in this energy domain. The Laue lenses huge potential is strictly connected with the mass production of properly bent crystals and with their alignment that must be done with an accuracy better than 10 arcsec. To prove the increase of the Laue lenses TRL from 3-4 to a value of 6, a demonstrator will be presented, made with ~120 bent crystals capable to focus photons in the 90–180 keV energy range. To prove its reliability, thermal and mechanical test will be performed on the prototype. Thanks to this TRL improvement a mission equipped with broadband Laue lenses can be proposed: either as a free-flight medium class satellite (50- 600 keV energy pass-band) or in a cluster of three coaligned mini satellites: low energy Laue lens (50- 100 keV), a medium energy lens (90-300 keV) and a high energy Laue lens (250-600 keV).
