Photon diagnostics for the X-ray FELs at TESLA
[DESY-TESLA-FEL-2000-13]
18 pp. ()
An X-ray diagnostic station will be installed for each of the XFEL undulator beamlines atTESLA. Primary purpose of the X-ray diagnostics is to provide an additional tool foralignment and commissioning of the numerous undulator cells along an XFEL beamlineindependently from electron beam based alignment procedures.

Magnet design of a prototype structure for the X-ray FELs at TESLA
[TESLA-FEL 2000-12]
14 pp. () [10.3204/PUBDB-2018-04067]  GO
XFEL undulators for the TESLA project require high quality in order to drive the SASE process into saturation. On the other hand, as large quantities are needed for the five SASE undulators, it is rather important not to oversize the undulator design. [...]

Ein SIMATIC basiertes Kontrollsystem für die Undulatoren des TESLA Röntgenlasers
[TESLA-FEL 2000-09]
TESLA-FEL Reports 42 pp. () [10.3204/PUBDB-2018-04064]  GO
Die Undulatorsysteme für den Röntgen FEL bei TESLA werden über 300m lang sein und in ca 506.1m lange Einheiten, sogenannte Zellen, unterteilt werden. Damit an den einzelnenUndulatorsystemen die Wellenlänge des abgestrahlten Lichts unabhängig von desElektronenstrahlenergie eingestellt werden kann muß das Gap im gesamten System mit großerGenauigkeit verstellt werden können.

PETRA IV: the ultralow-emittance source project at DESY
The PETRA IV project aims at upgrading the present synchrotron radiation source PETRA III at DESY into an ultralow-emittance source. Being diffraction limited up to X-rays of about 10 keV, PETRA IV will be ideal for three-dimensional X-ray microscopy of biological, chemical and physical processes under realistic conditions at length scales from atomic dimensions to millimetres and time scales down to the sub-nanosecond regime [...]
