DEVELOPMENTS OF THE ASI NHXM PROGRAM
 NHXM is the ASI program with the aim to launch a new mission for Hard X-ray
observations
 Pre-phase A study, in the NHXM frame, mainly relevant to the Simbol-X
collaboration has been conducted; 9/2006 – 1/2007.
 NHXM phase A contract with Mirror technological development, MSC satellite of
Simbol-X development and Exit-Sat Satellite development started in 7/2007.
 First change with deeper analysis on mirror technology (Ni-Co electroforming,
Multilayer deposition)
 Second change with the development of a common platform for MSC and DSC (to
be used also for EXIT-SAT)
 Conclusion of the NHXM phase A (Simbol-X and Exit-Sat phase A), 1/2009. Initial
duration of 13 months, extended to 18 months.
 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.

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

SIMBOL-X MAIN CARACHTERISTICS
Concept:

high-energy new generation telescope, spectral range
from classical X-rays to hard X-rays (0.5-80 keV); 2
orders of magnitude better in sensibility and spatial
resolution.

Long focal length using Formation Flying.

Mirror and Detector mounted on two different
spacecrafts in Formation Flying.

High elliptical orbit (20.000-180.000 km)
Field-of-View
12 arcmin
Absolute
pointing
Mirror
Satellite
20 arcsec
Line-of-Sight
Reconstruction
Optics:


Shells mechanics from of Italian know how

Reflecting material: multilayer to increase the field of
view and the spectral bandwidth
Detector
Satellite
Focal plane:

Passive collimator with active anticoincidence

Two superposed spectro-imager (Low Energy 0.5–20
keV; High Energy CdTe 15–100 keV)

CONCLUSIONS
 During the last period, ASI made big efforts to pursue the NHXM Program
(financial and HR).
 We envisaged a broad involvement by the Italian community, either scientific and
industrial.
 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.
 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.
 ASI (and the collaboration network) has availability of know how, results and
documentation on the above mentioned projects.
