Abstract: Abstract Performing polarimetry in the soft X-ray range, from 1 keV to 15 keV, is a topic of high interest in the astrophysical community. However, for instrumental reasons, soft X-ray polarimetry has been performed only once so far by a mission on board the OSO-8 satellite in 1975. Since the early 2000's, thanks to the development of Micro Pattern Gaseous Detectors (MPGD), it is possible to perform polarimetry by measuring the azimuthal scattering anisotropy of the photoelectrons created during the detection of soft X-rays by photoelectric effect. The Caliste-MM detector is a gaseous polarimeter, using a novel design of contactless readout electronics to read the signal developed in the resistive anode of a piggyback micromegas detector. In this paper we present polarimetry measurements obtained with the Caliste-MM detector at the Soleil synchrotron facility. Photoelectrons tracks obtained in the beamline are shown, and the reconstruction method to find the photoelectrons azimuthal angle is described. We conclude by presenting the modulation curve obtained at 8 keV, with a modulation factor of the detector reaching 88%. [ABSTRACT FROM AUTHOR]
