Scattering polarimetry for x-ray astronomy by means of scintillating fibers

Scattering polarimetry is based on the detection of photons scattered by a target at angles close to 90 degree(s). For Astrophysical purposes in the hard X-ray band, where a large collecting area is needed and optics are ineffective, we suggest to produce a large array of very thin detectors made of scintillating fibers read by optical fibers. We computed, by means of MCNP code the response of some possible configurations with different thickness of plastic scintillator, CsI and CaF2.
