A Sealed Gas Pixel Detector for X-ray Astronomy
R. Bellazzini, G. Spandre, M. Minuti +13
We report on the results of a new, sealed, Gas Pixel Detector. The very compact design and the absence of the gas flow system, make this detector substantially ready for use as foc…
POLARIX: a small mission of x-ray polarimetry
Enrico Costa, Ronaldo Bellazzini, Paolo Soffitta +24
X-Ray Polarimetry can be now performed by using a Micro Pattern Gas Chamber in the focus of a telescope. It requires large area optics for most important scientific targets. But si…
An X-ray polarimeter for hard X-ray optics
Fabio Muleri, Ronaldo Bellazzini, Enrico Costa +23
Development of multi-layer optics makes feasible the use of X-ray telescope at energy up to 60-80 keV: in this paper we discuss the extension of photoelectric polarimeter based on…
A photoelectric polarimeter for XEUS: a new window in x-ray sky
Ronaldo Bellazzini, Luca Baldini, Francesco Bitti +18
XEUS is a large area telescope aiming to rise X-ray Astronomy to the level of Optical Astronomy in terms of collecting areas. It will be based on two satellites, locked on a format…
