Two Colors at the SASE3 Line of the European XFEL: Project Scope and First Measurements
39th International Free-Electron Laser Conference, FEL2019, HamburgHamburg, Germany, 26 Aug 2019 - 30 Aug 20192019-08-262019-08-30 JACoW Publishing, Geneva, Switzerland 195-198 () [10.18429/JACOW-FEL2019-TUP062]  GO
The European XFEL is a high-repetition rate facility that generates high-power SASE radiation pulses in three beamlines. A joint upgrade project, with Finnish universities, to equip the SASE3 beamline with a chicane has been recently approved to generate two SASE pulses with different photon energies and temporal separation.

Parallel Operation of SASE1 and SASE3 at the European XFEL
39th International Free-Electron Laser Conference, FEL2019, HamburgHamburg, Germany, 26 Aug 2019 - 30 Aug 20192019-08-262019-08-30 JACoW Publishing, Geneva, Switzerland 25-28 () [10.18429/JACOW-FEL2019-TUA01]  GO
At the European XFEL a hard X-Ray SASE FEL (SA-SE1) and a soft X-Ray SASE FEL (SASE3) share in series the same electron beamline. This configuration couples the operation conditions for both undulators and their subsequent user experiments in terms of SASE in-tensity and background. [...]

First Measurements with the K-Monochromator at the European XFEL
Hard X-ray free-electron lasers (XFELs) generate intense coherent X-ray beams by passing electrons through undulators, i.e. very long periodic magnet structures, which extend over hundreds of meters. [...]

Collimator Performance Study at the European XFEL
10th International Particle Accelerator Conference, IPAC 2019, MelbourneMelbourne, Australia, 19 May 2019 - 24 May 20192019-05-192019-05-24 JACoW Publishing, Geneva, Switzerland 4 pp. () [10.18429/JACOW-IPAC2019-TUPRB019]  GO
Beam halo collimation is of great importance for the high repetition rate operation at the European XFEL and for the future CW machines. At the European XFEL several different types of collimators are installed at different locations of the beam line, which include the gun collimators, the bunch compressor collimators, and the main and supplementary collimators in the collimation section.
