The challenge offered by X-ray lasers

Sp5-a the Challenge of X-ray Free-electron Lasers Structural Studies with X-ray Lasers

The history of the living world can be summarised as an elaboration of ever more perfect eyes within a Cosmos in which there is always something new to be seen (Teilhard du Chardin, 1955). Today, the bottleneck in the atomic resolution imaging of biological systems is a fundamental need for crystals. This limits the scope of detailed structural analysis to macromolecules and macromolecular asse...

Optimum driving a Z-pinch for soft X-Ray lasers

A capillary plasma z-pinch as an alternative active medium of soft X-Ray lasers was studied experimentally and theoretically. The theoretical analysis was based on the self consistent solution of the so called “snow plow” model. The dynamics of pinched plasma is determined by the capillary parameters and by the time dependence of electrical current passing through it. The current time dependenc...

X-ray free-electron lasers

In a free-electron laser (FEL) the lasing medium is a high-energy beam of electrons flying with relativistic speed through a periodic magnetic field. The interaction between the synchrotron radiation that is produced and the electrons in the beam induces a periodic bunching of the electrons, greatly increasing the intensity of radiation produced at a particular wavelength. Depending only on a p...
