X-ray powder diffraction at the XRD1 beamline atLNLS
(Int Union Crystallography, 2016)
Various upgrades have been completed at the XRD1 beamline at the Brazilian synchrotron light source (LNLS). The upgrades are comprehensive, with changes to both hardware and software, now allowing users of the beamline to ...
Electronic stopping cross sections for protons in Al2O3: an experimental and theoretical study
(SPRINGERNEW YORK, 2012)
The electronic stopping cross section (SCS) of Al2O3 for proton beams is studied both experimentally and theoretically. The measurements are made for proton energies from 40 keV up to 1 MeV, which cover the maximum stopping ...
Multimission observations of the old nova GK Per during the 2015 outburst
(Oxford University Press, 2017-07)
GK Per, a classical nova of 1901, is thought to undergo variable mass accretion on to a magnetized white dwarf (WD) in an intermediate polar system (IP). We organized a multi-mission observational campaign in the X-ray and ...
L shell X-ray production cross sections for Sr and Mo by proton impact
(Pergamon-Elsevier Science Ltd, 2019-01)
Total L X-ray production cross sections were measured for Sr and Mo by proton impact. Proton energies ranged from 200 keV to 3 MeV. K shell cross sections of Ti and Cu samples were obtained in order to normalize our results, ...
Monte Carlo assessment of low energy electron range in liquid water and dosimetry effects
(Istituti Editoriali e Poligrafici Internazionali, 2020-12)
The effects of low energy electrons in biological tissues have proved to lead to severe damages at the cellular and sub-cellular level. It is due to an increase in the relative biological effectiveness (RBE) of these ...
THE EVOLUTION OF SWIFT/BAT BLAZARS AND THE ORIGIN OF THE MeV BACKGROUND
(IOP PUBLISHING LTD, 2009-07-01)
We use three years of data from the Swift/Burst Alert Telescope ( BAT) survey to select a complete sample of X-ray blazars above 15 keV. This sample comprises 26 flat-spectrum radio quasars (FSRQs) and 12 BL Lacertae (BL ...
