Iranian Light Source Facility (ILSF) is a new 3 GeV synchrotron radiation laboratory in the Middle East. The ILSF storage ring (SR) is based on a Five-Bend Achromat lattice, providing a beam emittance of 0.48 nm rad. The ring is consisting of 100 pure dipole, 320 quadrupole and 320 sextupole magnets. In this paper, we present some design features of the SR magnets and discuss their detailed ph...
Background: An early diagnosis of breast cancer relates directly to an accurate treatment plan and strategy. Early detection of breast cancer before its development would be a significant reduction of morbidity and mortality rates. The aim of this preliminary study is to investigate the sensitivity of Wide Angle X-ray diffraction (WAXRD) method on women hair samples of healthy and breast cancer...
The possibility of inserting an optical klystron on the storage ring of an Iranian Light Source Facility as a Synchrotron Radiation Free electron Laser for coherence harmonic generation in the soft x-ray spectrum has been studied. The study has been performed using the 3D FEL simulation code GENESIS 1.3 and in accordance with the available characteristic parameters of ISLF. Different potential ...
The scientific research regarding investigation, characterization and protection of the archeological specimens is manifested through a notable participation of multidisciplinary subjects and experts, scientists and archeometrists. One of the main principals which are considered by archaeometrists in the study of the precious specimens is the utilizing nondestructive methods. As an example, in ...
The broadband SEDs of blazars exhibit two broad spectral components which in leptonic emission models are attributed to synchrotron radiation and SSC radiation of relativistic electrons. During high state phases the highfrequency SSC component often dominates over the low-frequency synchrotron component implying that the inverse Compton SSC losses of electrons are at least equal to or greater t...
Fast radio bursts (FRBs) are mysterious transient sources. If extragalactic, as suggested by their relative large dispersion measures, their brightness temperatures must be extremely high. Some FRB models (e.g., young pulsar model, magnetar giant flare model, or supra-massive neutron star collapse model) suggest that they may be associated with a synchrotron nebula. Here we study a synchrotron-...
