|Issue Date:||2016||Volume:||High Energy, Optical, and Infrared Detectors for Astronomy VII||Series:||PROCEEDINGS OF SPIE||Number:||9915||First Page:||991528||Abstract:||COMpton Polarimeter with Avalanche Silicon readout (COMPASS) is a research and development project that aims to measure the polarization of X-ray photons through Compton Scattering. The measurement is obtained by using a set of small rods of fast scintillation materials with both low-Z (as active scatterer) and high-Z (as absorber), all read-out with Silicon Photomultipliers. By this method we can operate scattering and absorbing elements in coincidence, in order to reduce the background. In the laboratory we are characterising the SiPMs using different types of scintillators and we are optimising the performances in terms of energy resolution, energy threshold and photon tagging efficiency. We aim to study the design of two types of satellite-borne instruments: a focal plane polarimeter to be coupled with multilayer optics for hard X-rays and a large area and wide field of view polarimeter for transients and Gamma Ray Bursts. In this paper we describe the status of the COMPASS project, we report about the laboratory measurements and we describe our future perspectives. <P />||Conference Name:||High Energy, Optical, and Infrared Detectors for Astronomy VII||Conference Place:||Edinburgh, UK||Conference Date:||26 June-1 July, 2016||URI:||http://hdl.handle.net/20.500.12386/24353||URL:||https://www.spiedigitallibrary.org/conference-proceedings-of-spie/9915/1/Silicon-photomultipliers-as-readout-elements-for-a-Compton-Effect-polarimeter/10.1117/12.2232572.short?SSO=1||ISSN:||0277-786X||ISBN:||9781510602090||DOI:||10.1117/12.2232572||Bibcode ADS:||2016SPIE.9915E..28D||Fulltext:||open|
