Polarization properties of X-ray tubes used for Imaging X-ray Polarimetry Explorer calibration

چکیده
In this work, we measured the polarization properties of X-rays emitted from X-ray tubes, which were used during calibration instrument onboard Imaging Polarimetry Explorer (IXPE). tubes are as a source unpolarized to calibrate response gas pixel detectors radiation. However, even though characteristic fluorescent emission lines unpolarized, continuum bremsstrahlung can be polarized based on geometry accelerated electrons and photons. Hence, characterizing contribution is interest, also for future measurements. We find that, when parallel photons, they perpendicular, increases with energy, expected theoretical predictions. A comparison predictions shown.

Evaluation of multifunctional targeted gold nanoparticles on X-ray attenuation in nasopharyngeal cancer cells by X- ray imaging
Introduction: Head-and-neck cancer is the sixth most common cancer worldwide with the number of cases consistently increasing in developing countries. Successful development of effective, safe and cost effective nanoprobes for head-and-neck cancer targeting imaging is a big challenge. This study is aimed to develop cysteamine-folate conjugated gold nanoparticles (F-Cys-AuNPs) a...
متن کاملX-ray Timing beyond the Rossi X-ray Timing Explorer
With its ability to look at bright galactic X-ray sources with sub-millisecond time resolution, the Rossi X-ray Timing Explorer (RXTE) discovered that the X-ray emission from accreting compact stars shows quasi-periodic oscillations on the dynamical timescales of the strong field region. RXTE showed also that waveform fitting of the oscillations resulting from hot spots at the surface of rapidl...
متن کاملPolarization properties of X-ray millisecond pulsars
Radiation of X-ray bursts and of accretion shocks in weakly magnetized neutron stars in low-mass X-ray binaries is produced in plane-parallel atmospheres dominated by electron scattering. We first discuss polarization produced by single (non-magnetic) Compton scattering, in particular the depolarizing effect of high electron temperature, and then the polarization due to multiply electron scatte...
