DEVELOPMENTS OF THE ASI NHXM PROGRAM v NHXM is the ASI program with the aim to launch a new mission for Hard X-ray observations v Pre-phase A study, in the NHXM frame, mainly relevant to the Simbol-X collaboration has been conducted; 9/2006 – 1/2007. v NHXM phase A contract with Mirror technological development, MSC satellite of Simbol-X development and Exit-Sat Satellite development started in 7/2007. v First change with deeper analysis on mirror technology (Ni-Co electroforming, Multilayer deposition) v Second change with the development of a common platform for MSC and DSC (to be used also for EXIT-SAT) v Conclusion of the NHXM phase A (Simbol-X and Exit-Sat phase A), 1/2009. Initial duration of 13 months, extended to 18 months. v A further technological study (only on X-rays multilayer mirrors), continuation of the work performed during the NHXM phase A, has been initiated in 3/2009, and still on going. 12 -13 novembre 2009 New Hard X-ray Mission Workshop; ASDC, Frascati Ing.

NHXM PHASE A: THE PEOPLE v Continuous collaboration with CNES on Simbol-X program, while only Italian involvement on EXIT-SAT mission. v Continuous improvement of the knowledge by confrontation with our program partners v Conclusion of the ASI-CNES collaboration on Simbol-X Program, 4/2009. v Internal Agency resources (8+1 persons). v INAF resources (from different locations and institute) v Industrial resources (TAS-I, MLT, BCV, TPZ, INAF-OAB) v Large but efficient integrated team working on NHXM for almost 2 years. v Once again, demonstrated ability for such a team, to deal and interact productively with other international partners. 12 -13 novembre 2009 New Hard X-ray Mission Workshop; ASDC, Frascati Ing.

NHXM PHASE A: THE COMMON PLATFORM DSC HXMT HEXITSAT SIMBOL-X MSC 12 -13 novembre 2009 New Hard X-ray Mission Workshop; ASDC, Frascati Ing. Mauro Piermaria 8

SIMBOL-X MAIN CARACHTERISTICS Concept: v high-energy new generation telescope, spectral range from classical X-rays to hard X-rays (0. 5 -80 ke. V); 2 orders of magnitude better in sensibility and spatial resolution. Field-of-View 12 arcmin Mirror Satellite Absolute pointing 20 arcsec v Long focal length using Formation Flying. v Mirror and Detector mounted on two different spacecrafts in Formation Flying. v High elliptical orbit (20. 000 -180. 000 km) Line-of-Sight Reconstruction 4. 7 arcsec 20 m Optics: v Shells mechanics from of Italian know how v Reflecting material: multilayer to increase the field of view and the spectral bandwidth Detector Satellite Focal plane: v Passive collimator with active anticoincidence v Two superposed spectro-imager (Low Energy 0. 5– 20 ke. V; High Energy Cd. Te 15– 100 ke. V) 12 -13 novembre 2009 New Hard X-ray Mission Workshop; ASDC, Frascati +/-1 cm Ing. Mauro Piermaria 9

EXIT-SAT: MAIN SPECIFICATIONS v Four Mirror modules (12 mirror each), multilayer optics. v Four detectors, each aligned with the corresponding mirror v Focal distance 8 -10 m (deployable truss) v 1000 -1500 Kg /600 W Satellite class v Near circular equatorial orbit, 600 Km altitude (Beppo-sax like). v Utilisation of the Malindi Station 12 -13 novembre 2009 New Hard X-ray Mission Workshop; ASDC, Frascati Ing.

CONCLUSIONS v During the last period, ASI made big efforts to pursue the NHXM Program (financial and HR). v We envisaged a broad involvement by the Italian community, either scientific and industrial. v The Simbol-X project, and the collaboration with the French partners, unfortunately stopped, brought a lot of experience on this kind of mission, for both scientific and engineering issues. v Feasibility of Exit-Sat and Simbol-X missions at the end of the projects phase A has been proved. By the way, some Items of Exit-Sat mission need to be further investigated. v ASI (and the collaboration network) has availability of know how, results and documentation on the above mentioned projects. 12 -13 novembre 2009 New Hard X-ray Mission Workshop; ASDC, Frascati Ing.
