Il progetto SWORDS realizzerà strumentazione per la misura della polarizzazione lineare dei raggi X duri dei brillamenti solari per trovare una chiara correlazione con l’occorrenza di Emissioni di Massa Coronale (CME) ed eventi di Solar Energetic Particles (SEP) e per includere la polarimetria dei raggi X nelle reti di forecast di Space Weather, come ad esempio il progetto ASPIS dell’ASI (base dati per lo studio dello Space Weather). Lo studio di fase A della missione CUSP (Cubesat Solar Polarimeter) per una costellazione di due cubesat è stata approvata in risposta al bando per future missioni CubeSat di ASI.
The SWORDS project will built instrumentation for measuring the linear polarization of hard X-rays of solar flares to find a correlation between polarization and the occurrence of Coronal Mass Emissions (CME) Solar Energetic Parts (SEP) events and to include the polarimetry of X-rays in the Space Weather forecast networks, such as the ASI ASPIS project (database for the study of Space Weather). A Phase A study of the CUSP (Cubesat Solar Polarimeter) mission (a constellation of two cubesats) was approved by ASI in the framework of a call for future CubeSat missions.

Titolo: The gas pixel detector as a solar X-ray polarimeter and imager

Anno pubblicazione:2012
Abstract: The Sun is the nearest astrophysical source with a very intense emission in the X-ray band. The study of energetic events, such as solar flares, can help us to understand the behaviour of the magnetic field of our star. There are in the literature numerous studies published about polarization predictions, for a wide range of solar flares models involving the emission from thermal and/or non-thermal processes, but observations in the X-ray band have never been exhaustive. The gas pixel detector (GPD) was designed to achieve X-ray polarimetric measurements as well as X-ray images for far astrophysical sources. Here we present the possibility to employ this instrument for the observation of our Sun in the X-ray band.

Abstract: 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.

Anno pubblicazione:2013
Abstract: In this work we present an active Compton scattering polarimeter as a focal plane instrument able to extend the X-ray polarimetry towards hard X-rays. Other authors have already studied various instrument design by means of Monte Carlo simulations, in this work we will show for the first time the experimental measurements of ‘‘tagging efficiency’’ aimed to evaluate the polarimeter sensitivity as a function of energy. We performed a characterization of different scattering materials by measuring the tagging efficiency that was used as an input to the Monte Carlo simulation. Then we calculated the sensitivity to polarization of a design based on the laboratory set-up. Despite the geometry tested is not optimized for a realistic focal plane instrument, we demonstrated the feasibility of polarimetry with a low energy threshold of 20 keV. Moreover we evaluated a minimum detectable polarization of 10% for a 10 mCrab source in 100 ks between 20 and 80 keV in the focal plane of one multilayer optics module of NuSTAR. The configuration used consisted of a doped p-terphenyl scatterer 3 cm long and 0.7 cm of diameter coupled with a 0.2 cm thick LaBr3 absorber.

Abstract: Advanced Astronomy for Heliophysics Plus (ADAHELI+) is a project concept for a small solar and space weather mission with a budget compatible with an European Space Agency (ESA) S-class mission, including launch, and a fast development cycle. ADAHELI+ was submitted to the European Space Agency by a European-wide consortium of solar physics research institutes in response to the “Call for a small mission opportunity for a launch in 2017,” of March 9, 2012. The ADAHELI+ project builds on the heritage of the former ADAHELI mission, which had successfully completed its phase-A study under the Italian Space Agency 2007 Small Mission Programme, thus proving the soundness and feasibility of its innovative low-budget design. ADAHELI+ is a solar space mission with two main instruments: ISODY+: an imager, based on Fabry–Pérot interferometers, whose design is optimized to the acquisition of highest cadence, long-duration, multiline spectropolarimetric images in the visible/near-infrared region of the solar spectrum. XSPO: an x-ray polarimeter for solar flares in x-rays with energies in the 15 to 35 keV range. ADAHELI+ is capable of performing observations that cannot be addressed by other currently planned solar space missions, due to their limited telemetry, or by ground-based facilities, due to the problematic effect of the terrestrial atmosphere.

Abstract: The measurement of X-ray polarization from solar flares is a scientific challenge which did not give any exhaustive result so far. X-ray polarimetry would be a probe of the solar flares physics making possible to study directly the magnetic reconnection and particle acceleration in the solar atmosphere of active regions where flares take place. New instrumentation specifically developed to measure the polarization of X-ray is needed to obtain results with adequate significance. The photoelectric polarimeter Gas Pixel Detector (GPD), originally developed to observe astrophysical sources other then the Sun, can address also solar science. The recent development of a new detector prototype effective in the hard X-rays makes suitable this polarimeter to examine the solar flares spectral region in which typically the non-thermal bremsstrahlung emission, expected to be highly polarized, arises with respect to the thermal bremsstrahlung whose polarization is expected to be marginal. The GPD versatility and small size make such an instrument suitable to fly on board of small space missions.

Abstract: The possibility to perform polarimetry in the soft X-ray energy band (2-10 keV) with the Gas Pixel Detector, filled with low Z mixtures, has been widely explored so far. The possibility to extend the technique to higher energies, in combination with multilayer optics, has been also hypothesized in the past, on the basis of simulations. Here we present a recent development to perform imaging polarimetry between 6 and 35 keV, employing a new design for the GPD, filled with a Ar-DME gas mixture at high pressure. In order to improve the efficiency by increasing the absorption gap, while preserving a good parallel electric field, we developed a new configuration characterized by a wider gas cell and a wider GEM. The uniform electric field allows to maintain high polarimetric capabilities without any decrease of spectroscopic and imaging properties. We present the first measurements of this prototype showing that it is now possible to perform imaging and spectro-polarimetry of hard X-ray sources.
