Low energy polarization sensitivity of the Gas Pixel Detector
F. Muleri, P. Soffitta, L. Baldini +15
An X-ray photoelectric polarimeter based on the Gas Pixel Detector has been proposed to be included in many upcoming space missions to fill the gap of about 30 years from the first…
An X-ray Polarimeter for HXMT Mission
Enrico Costa, Ronaldo Bellazzini, Gianpiero Tagliaferri +17
The development of micropixel gas detectors, capable to image tracks produced in a gas by photoelectrons, makes possible to perform polarimetry of X-ray celestial sources in the fo…
A very compact polarizer for an X-ray polarimeter calibration
Fabio Muleri, Paolo Soffitta, Ronaldo Bellazzini +10
We devised and built a light, compact and transportable X-ray polarized source based on the Bragg diffraction at nearly 45 degrees. The source is composed by a crystal coupled to a…
Imaging with the invisible light
R. Bellazzini, G. Spandre, A. Brez +12
We describe a UV photo-detector with single photon(electron) counting and imaging capability. It is based on a CsI photocathode, a GEM charge multiplier and a self triggering CMOS…
