Chalcogenide materials are composed of S, Se or Te elements from group VI of the periodic table. For these elements, the sequence of S, Se and Te shows that bonding changes from molecular, covalent, to metallic. They are receiving extensive interest not only for application in advanced memories (Phase Change RAM, Current Bridge RAM) and photovoltaics (i.e. CZTS: Cooper Zinc Tin Sulfide), but...

Ions produced by ionization of the residual gas in electron storage rings can significantly degrade the performance of a machine and produce various beam instabilities. To cure more effectively these problems it is important to understand the ion dynamics in the accelerator. The ions undergo the effect of the electron beam crossing and go through strong transverse oscillations and a longitudinal...

The COXINEL experiment aims to demonstrate the free electron laser amplification with an electron beam produced by laser plasma acceleration.
For this, a transport line was designed and prepared at the Synchrotron SOLEIL. It consists of three permanent magnet quadrupoles with variable gradient (QUAPEVAs), a demixing chicane, a second set of electromagnetic quadrupoles and a 2 m undulator....
