X-ray Laser Research at Palaiseau
We present the soft X-ray laser experiments performed at Greco "Interaction Laser-Matisre" (Palaiseau). They are mainly concerned with Lithium-like ions of aluminum in plasmas produced by 1.06v Nd-laser. We describe the experimental set-up which performs time-dependent gain measurements. We report results showing a gain-length product of 2 2.5 for the 3d 5f line at 105.7 A . Comparison is made ...
متن کاملForty Years of X-Ray Binaries
In 2012 it was forty years ago that the discovery of the first X-ray binary Centaurus X-3 became known. That same year it was discovered that apart from the High-Mass X-ray Binaries (HMXBs) there are also Low-Mass X-ray Binaries (LMXBs), and that Cygnus X-1 is most probably a black hole. By 1975 also the new class of Be/X-ray binaries was discovered. After this it took 28 years before ESAs INTE...
متن کاملX - Ray Diffuse Scattering 9 . X - Ray Diffuse Scattering Academic and Research Staff
In this research program, modern x-ray scattering techniques are used to study the structures and phase transitions in novel states of condensed matter. We have two principal experimental facilities. At M.I.T. we have two high-resolution computer controlled x-ray spectrometers using a high intensity rotating anode x-ray generator. Two more spectrometers are currently under development. The angu...

In this research program, modern x-ray scattering techniques are used to study the structures and phase transitions in novel states of condensed matter. We have two principal experimental facilities. At M.I.T. we have three high-resolution computer controlled x-ray spectrometers using either a conventional or high intensity rotating anode x-ray generator. The angular resolution can be made as f...
متن کاملEvaluation 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...
