Sources

In recent years, light sources have been central to research. Whether they are small enough to sit on a "table", or form large instruments of hundreds of meters, they help to push the scale limits of spatial-temporal studies. In this sense, recent free-electron lasers or other sources of high-order harmonic generation are the subject of intense development, while some of their characteristics are so far impossible to measure.

From 15^th to 19^th September, SOLEIL and the International Agency for Atomic Energy* (IAEA) were organizing a reflexion week on the management of accelerators.

LUNEX5 (free electron Laser Using a New accelerator for the Exploitation of X-ray radiation of 5th generation), a new advanced Free-Electron Laser (FEL) project proposed by a consortium of laboratories in France, aims at investigating the production of ultra-short (fs), intense, and coherent pulses in the soft X-ray region (20 - 4 nm).
