Abstract
In the history of X-ray astronomy the only polarimetric measurement obtained with high significance dates back to the late '70s, when the Crab Pulsar Wind Nebula was observed. X-ray polarimetry remains a widely unexplored scientific field so far. The new 2-10 keV polarimetry era will be opened by GEMS satellite in the next future, while the extension to higher energies is still a challenging goal. The photoelectric polarimeter Gas Pixel Detector (GPD) could be employed with an Ar based gas mixture to measure the solar flares X-ray polarization up to about 35 keV, while coupling it with a Compton scattering polarimeter it would be possible to extend the energy range of measurements to higher energies.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
