1. Equalizing the Pixel Response of the Imaging Photoelectric Polarimeter On-Board the IXPE Mission

Abstract: The Gas Pixel Detector is a gas detector, sensitive to the polarization of X-rays, currently flying on-board IXPE - the first observatory dedicated to X-ray polarimetry. It detects X-rays and their polarization by imaging the ionization tracks generated by photoelectrons absorbed in the sensitive volume, and then reconstructing the initial direction of the photoelectrons. The primary ionization charge is multiplied and ultimately collected on a finely-pixellated ASIC specifically developed for X-ray polarimetry. The signal of individual pixels is processed independently and gain variations can be substantial, of the order of 20%. Such variations need to be equalized to correctly reconstruct the track shape, and therefore its polarization direction. The method to do such equalization is presented here and is based on the comparison between the mean charge of a pixel with respect to the other pixels for equivalent events. The method is shown to finely equalize the response of the detectors on board IXPE, allowing a better track reconstruction and energy resolution, and can in principle be applied to any imaging detector based on tracks., Comment: Accepted for publication in The Astronomical Journal. 10 pages, 19 figures

Abstract: IXPE (Imaging X-ray Polarimetry Explorer) is a NASA Small Explorer mission -- in partnership with the Italian Space Agency (ASI) -- dedicated to X-ray polarimetry in the 2--8 keV energy band. The IXPE telescope comprises three grazing incidence mirror modules coupled to three detector units hosting each one a Gas Pixel Detector (GPD), a gas detector that allows measuring the polarization degree by using the photoelectric effect. A wide and accurate ground calibration was carried out on the IXPE Detector Units (DUs) at INAF-IAPS, in Italy, where a dedicated facility was set-up at this aim. In this paper, we present the results obtained from this calibration campaign to study the IXPE focal plane detector response to polarized radiation. In particular, we report on the modulation factor, which is the main parameter to estimate the sensitivity of a polarimeter., Comment: Accepted for publication on The Astronomical Journal

Abstract: IXPE is a Small Explorer mission that was launched at the end of 2021 to measure the polarization of X-ray emission from tens of astronomical sources. Its focal plane detectors are based on the Gas Pixel Detector, which measures the polarization by imaging photoelectron tracks in a gas mixture and reconstructing their initial directions. The quality of the single track, and then the capability of correctly determining the original direction of the photoelectron, depends on many factors, e.g., whether the photoelectron is emitted at low or high inclination with respect to the collection plane or the occurrence of a large Coulomb scattering close to the generation point. The reconstruction algorithm used by IXPE to obtain the photoelectron emission direction, also calculates several properties of the shape of the tracks which characterize the process. In this paper we compare several such properties and identify the best one to weight each track on the basis of the reconstruction accuracy. We demonstrate that significant improvement in sensitivity can be achieved with this approach and for this reason it will be the baseline for IXPE data analysis., Comment: 16 pages, 2 Tables, 8 Figures Accepted for publication The Astronomical Journal

Abstract: Scheduled to launch in late 2021, the Imaging X-ray Polarimetry Explorer (IXPE) is a NASA Small Explorer Mission in collaboration with the Italian Space Agency (ASI). The mission will open a new window of investigation - imaging X-ray polarimetry. The observatory features 3 identical telescopes each consisting of a mirror module assembly with a polarization-sensitive imaging X-ray detector at the focus. A coilable boom, deployed on orbit, provides the necessary 4-m focal length. The observatory utilizes a 3-axis-stabilized spacecraft which provides services such as power, attitude determination and control, commanding, and telemetry to the ground. During its 2-year baseline mission, IXPE will conduct precise polarimetry for samples of multiple categories of X-ray sources, with follow-on observations of selected targets.

Abstract: IXPE scientific payload comprises of three telescopes, each composed of a mirror and a photoelectric polarimeter based on the Gas Pixel Detector design. The three focal plane detectors, together with the unit which interfaces them to the spacecraft, are named IXPE Instrument and they will be built and calibrated in Italy; in this proceeding, we will present how IXPE Instrument will be calibrated, both on-ground and in-flight. The Instrument Calibration Equipment is being finalized at INAF-IAPS in Rome (Italy) to produce both polarized and unpolarized radiation, with a precise knowledge of direction, position, energy and polarization state of the incident beam. In flight, a set of four calibration sources based on radioactive material and mounted on a filter and calibration wheel will allow for the periodic calibration of all of the three IXPE focal plane detectors independently. A highly polarized source and an unpolarized one will be used to monitor the response to polarization; the remaining two will be used to calibrate the gain through the entire lifetime of the mission., Comment: 11 pages, 8 figures

Abstract: The Gas Pixel Detector is an X-ray polarimeter to fly on-board IXPE and other missions. To correctly measure the source polarization, the response of IXPE's GPDs to unpolarized radiation has to be calibrated and corrected. In this paper we describe the way such response is measured with laboratory sources and the algorithm to apply such correction to the observations of celestial sources. The latter allows to correct the response to polarization of single photons, therefore allowing great flexibility in all the subsequent analysis. Our correction approach is tested against both monochromatic and non-monochromatic laboratory sources and with simulations, finding that it correctly retrieves the polarization up to the statistical limits of the planned IXPE observations., Comment: Accepted for publication in The Astronomical Journal. 18 pages, 14 figures

Abstract: The Imaging X-ray Polarimetry Explorer is a mission dedicated to the measurement of X-ray polarization from tens of astrophysical sources belonging to different classes. Expected to be launched at the end of 2021, the payload comprises three mirrors and three focal plane imaging polarimeters, the latter being designed and built in Italy. While calibration is always an essential phase in the development of high-energy space missions, for IXPE it has been particularly extensive both to calibrate the response to polarization, which is peculiar to IXPE, and to achieve a statistical uncertainty below the expected sensitivity. In this paper we present the calibration equipment that was designed and built at INAF-IAPS in Rome, Italy, for the calibration of the polarization-sensitive focal plane detectors on-board IXPE. Equipment includes calibration sources, both polarized and unpolarized, stages to align and move the beam, test detectors and their mechanical assembly. While all these equipments were designed to fit the specific needs of the IXPE Instrument calibration, their versatility could also be used in the future for other projects., Comment: 17 pages, 25 figures

Abstract: While X-ray Spectroscopy, Timing and Imaging have improved verymuch since 1962, when the first astronomical non-solar source was discovered, especially with the launch of Newton/X-ray Multi-Mirror Mission, Rossi/X-ray Timing Explorer and Chandra/Advanced X-ray Astrophysics Facility, the progress of X-ray polarimetry has been meager. This is in part due to the lack of sensitive polarization detectors, in part due to the fate of approved missions and in part because the celestial X-ray sources appeared less polarized than expected. Only one positive measurement has been available until now. Indeed the eight Orbiting Solar Observatory measured the polarization of the Crab nebula in the 70s. The advent of techniques of microelectronics allowed for designing a detector based on the photoelectric effect in gas in an energy range where the optics are efficient in focusing X-rays. Herewe describe the Instrument, which is the major contribution of the Italian collaboration to the SmallExplorer mission called IXPE, the Imaging X-ray Polarimetry Explorer, which will be flown in late 2021. The instrument, is composed of three Detector Units, based on this technique, and a Detector Service Unit. Three Mirror Modules provided by Marshall Space Flight Center focus X-rays onto the detectors. In the following we will show the technological choices, their scientific motivation and the results from the calibration of the Instrument. IXPE will perform imaging, timing and energy resolved polarimetry in the 2-8 keV energy band opening this window of X-ray astronomy to tens of celestial sources of almost all classes., Comment: 25 pages, 12 figures, 5 tables (accepted for publication in Astronomical Journal)

Abstract: The NASA/ASI Imaging X-ray Polarimetry Explorer, which will be launched in 2021, will be the first instrument to perform spatially resolved X-ray polarimetry on several astronomical sources in the 2-8 keV energy band. These measurements are made possible owing to the use of a gas pixel detector (GPD) at the focus of three X-ray telescopes. The GPD allows simultaneous measurements of the interaction point, energy, arrival time, and polarization angle of detected X-ray photons. The increase in sensitivity, achieved 40 years ago, for imaging and spectroscopy with the Einstein satellite will thus be extended to X-ray polarimetry for the first time. The characteristics of gas multiplication detectors are subject to changes over time. Because the GPD is a novel instrument, it is particularly important to verify its performance and stability during its mission lifetime. For this purpose, the spacecraft hosts a filter and calibration set (FCS), which includes both polarized and unpolarized calibration sources for performing in-flight calibration of the instruments. In this study, we present the design of the flight models of the FCS and the first measurements obtained using silicon drift detectors and CCD cameras, as well as those obtained in thermal vacuum with the flight units of the GPD. We show that the calibration sources successfully assess and verify the functionality of the GPD and validate its scientific results in orbit; this improves our knowledge of the behavior of these detectors in X-ray polarimetry., Comment: 22 pages, 16 figures, published on Journal of Astronomical Telescopes, Instruments, and Systems

Abstract: The Imaging X-ray Polarimetry Explorer (IXPE) is a scientific observatory with the purpose of expand observation space adding polarization property to the X-ray source's currently measured characteristics. The mission selected in the context of NASA Small Explorer (SMEX) is a collaboration between NASA and ASI that will provide to observatory the instrumentation of focal plane. IXPE instrument is composed by three photoelectric polarimeters based on the Gas Pixel Detector (GPD) design, integrated by INFN inside the detector unit (DU) that comprises of the electrical interfaces required to control and communicate with the GPD. The three DUs are interfaced with spacecraft through a detector service unit (DSU) that collect scientific and ancillary data and provides a basically data handling and interfaces to manage the three DUs. AIV has been planned to combine calibration of DUs and Instrument integration and verification activities. Due the tight schedule and the scientific and functional requirements to be verified, in IAPS/INAF have been assembled two equipment's that work in parallel. The flight model of each DU after the environmental tests campaign was calibrated on-ground using the Instrument Calibration Equipment (ICE) and subsequently integrated in the instrument in the AIV-T process on a AIV and Calibration Equipment (ACE), both the facilities managed by Electrical Ground Support Equipment (EGSE) that emulate the spacecraft interfaces of power supply, functional and thermal control and scientific data collection. AIV activities test functionalities and nominal/off-nominal orbits activities of IXPE instrument each time a calibrated DU is connected to DSU flight model completing step by step the full instrument. Here we describe the details of instrumentation and procedures adopted to make possible the full integration and test activities compatibly with calibration of IXPE Instrument.

44. Antenna arrays emulate metamaterial-based carpet cloak over a wide angular and frequency bandwidth

Abstract: We present the concept and the design of an antenna-based device for restoring the reflection from a ground plane over a broad incidence angular range, when an arbitrarily large object is placed on it. The proposed device is based on fully passive antenna arrays, whose elements are properly connected to each other by following a mirrored version of the Van Atta configuration used for realizing retroreflective arrays. Thanks to its self-adaptive behavior, the device allows faithfully emulating the reflection from a flat metallic plane, regardless the incidence angle of the illuminating field. However, the antennas reduce the amount of reflected energy due to their intrinsic limits in absorption. Except for this aspect, it acts in a similar fashion as a carpet cloak, restoring the signal reflection from the ground, even in the presence of an extremely electrically large object. The concept is numerically and experimentally verified by covering an electrically large metallic triangular bump ( $2.8\lambda _{0}\times 5.6\lambda _{0}$ ) with a pair of equal antenna arrays. The proposed design may find application in radar and antenna systems as a thin, lightweight, and easy to design and fabricate solution for concealing electrically large objects over a wide frequency and angular bandwidth.

Abstract: In this contribution, we propose a fully passive antennas-based carpet cloak inspired by Van Atta array configuration for retroreflectors. We consider an electrically large triangular bump over a ground plane, whose sides are covered by two arrays of conventional half-wavelength dipoles. When illuminated by a plane wave, the energy is captured by the first array and transmitted beyond the obstacle by the second one. The VanAtta-inspired connection ensures the restoration of the reflection angle as if the bump were not present, mimicking the ground reflection. The proposed solution is able to overcome the intrinsic narrow frequency and angular bandwidths of conventional carpet cloaks based on metasurfaces. The performances have been numerically evaluated, showing the ability of the proposed setup to mimic the reflection from a ground plane for different illumination angles.

Abstract: In this contribution, we discuss a possible antenna-based cloak for overcoming the intrinsic narrow frequency and angular bandwidths of conventional metasurface-based cloaks. The idea is to use a fully passive antenna array to mimic the reflection from a ground plane even in presence of an electrically large metallic bump. Here, a triangular bump over a ground plane is cloaked covering both sides by a pair of conventional half-wavelength dipole arrays. Inspired by the Van Atta array configuration, we connect the antenna elements on one side to the other in order to restore the phase fronts as the bump were not present. The performances have been numerically evaluated, showing the ability of the proposed setup to mimic the reflection from a ground plane over the frequency operation band of the antenna elements. Wide angular bandwidth is achieved thanks to the self-adaptive nature of the proposed configuration.

Abstract: In this contribution, we present the main results of the recent and ongoing research activities on metamaterials developed as a joint collaboration between Roma Tre University and Finmeccanica. The main goal of the applied research is focused on the development of miniaturized microwave components for radar and communication systems. The exploitation of innovative metamaterial concepts has led to the development of innovative industrial products for passive beam-forming networks of polarimetric antennas and compact radiating systems. This research has been awarded with the Finmeccanica Innovation Award in 2014 and the Finmeccanica Innovation Award for young researchers in 2015, respectively. The research activities leading to these two prestigious industrial awards are briefly summarized in this paper.

Abstract: Microwave waveguides allow an effective transfer of electromagnetic energy through straight connection or well-rounded curves, but become rather inefficient in case of sharp bends or squeezed waveguide cross-sections. Here, we discuss the possibility to funnel the electromagnetic energy propagating in a waveguide through arbitrarily curved narrow channels hosting a metamaterial-inspired structure able to convert the propagating mode of the waveguide in an electric signal, and vice versa. We show experimentally how sharp bends can be inserted within these propagation channels of arbitrary lengths without introducing significant insertion losses. In particular, efficient energy funneling in 90°-, 180°-, and “S”-shaped bends are numerically and experimentally verified. The proposed reflectionless waveguide bends may find applications in modern radar and antenna systems, where the demand for space and weight reduction of the electromagnetic circuitry is ever growing.
