X-ray Polarimetry - INAF-IASF-Roma

Implementation of X-ray polarimetry with GPD in proposed missions:
- POLARIX
(ASI small mission, fasa A completed)
3 Jet-X optics (3,5 m FL, 20 ‘’ HED 500 cm 2 @ 2 keV, HEW=(20’’))
3 GPD (1-cm, 1-Atm, He-DME 20-80)
MDP 12 % in 10 5 s for 1 mCrab source (2-10 keV)
3.8 % in 10 5 s for 10 mCrab source (2-10 keV)
- NHXM
(Proposed ESA M3 Mission not selected)
1 of 4 Multi-layer optics (Pt-C) (10 m FL)
2 GPD : 1-cm, 1-Atm, He-DME (LEP) (2-10 keV);
3-cm 3-Atm Ar-DME (MEP) (6-35 keV)
MDP:
LEP 9.7 % in 10 5 s for 1 mCrab source (2-10 keV)
3.1 % in 10 5 s for 10 mCrab source (2-10 keV)
Costa, et al., Exp Ast 2010
MEP 13 % in 10 5 s for 1 mCrab source (6-35 keV)
4.1 % in 10 5 for 10 mCrab source (6-35 keV)
In study (HEP, Compton scattering)
MDP 7.2 % for 10 mCrab in 10 5 s (20-80 keV)

Soffitta et al. SPIE 2010
(ESA/NASA/JAXA Large Mission Evolved in Athena with no polarimeter on-board)
Area= 2.5 m 2 FL = 20 m HEW= 5’’ XPOL: MDP 1 % 1 mCrab 10 5 s.
