TL;DR: In this article, the authors dealt with TTF/FLASH in the XFEL context, general layout of the X-FEL facility, the X FEL accelerator, undulators for SAES and spontaneous emission, infrastructure and auxiliary systems, commissioning and operation, project management and organization, cost and time schedule.

TL;DR: The European XFEL as discussed by the authors is a hard X-ray free-electron laser (FEL) based on a highelectron-energy superconducting linear accelerator, which allows for the acceleration of many electron bunches within one radio-frequency pulse of the accelerating voltage and, in turn, for the generation of a large number of hard Xray pulses.

TL;DR: In this paper, an extension of FLASH with a second undulator line and self-amplified spontaneous emission (SASE) is demonstrated in both FELs simultaneously.

TL;DR: In this article, a major extension of the user facility called FLASH II has been proposed by DESY in collaboration with the HZB in order to increase user beam time and to improve the radiation properties delivered to users.

TL;DR: In this paper, the equations of spin-orbit motion can be extended to a Hamiltonian system in 9-dimensional phase space by introducing a coupled spinorbit Poisson bracket (3) and Hamiltonian function (5).
