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…
Direct reading of charge multipliers with a self-triggering CMOS analog chip with 105k pixels at 50 micron pitch
R. Bellazzini, G. Spandre, M. Minuti +10
We report on a large active area (15x15mm2), high channel density (470 pixels/mm2), self-triggering CMOS analog chip that we have developed as pixelized charge collecting electrode…
Opening a New Window to Fundamental Physics and Astrophysics: X-ray Polarimetry
E. Costa, R. Bellazzini, P. Soffitta +25
An extensive theoretical literature predicts that X-ray Polarimetry can directly determine relevant physical and geometrical parameters of astrophysical sources, and discriminate b…
