Transverse deflecting structures are a powerful tool in beam dynamics studies. These devices produce correlations between transverse and the longitudinal offset. Therefore "top-view" images of the beam can be taken.
Measurements of longitudinal bunch profiles are relatively straight forward, while investigations of the longitudinal phase space or even the slice emittance are more involved....

Superconducting undulators (SCUs) have the potential to reach higher brilliance and flux with respect to the state of the art permanent magnet insertion devices. ANKA is collaborating with the industrial partner Babcock Noell GmbH (BNG) to realize NbTi conduction cooled planar devices for low emittance light sources, and is developing the instrumentation to characterize the magnetic field...

SINBAD (Short Innovative Bunches and Accelerators at DESY) is a planned multi-purpose research and development facility at DESY. The SINBAD linac aims to produce low charge (0.2 - 50 pC), ultra-short (from few fs to sub-fs) and ultra-stable (arrival-time jitter less than 10 fs ) electron bunches with energies up to 200 MeV, which will be used for explorations in ultra-fast science as well as...

The use of high brightness electron beams in Free Electron Laser (FEL) applications is of increasing importance. One of the most promising methods to generate such beams is the shaping of the photocathode laser pulses. It was already demonstrated that temporal and transverse flat-top laser pulses can produce very low emittance beams. Nevertheless, due to beam simulations further improvements...

The Photo Injector Test facility at DESY, Zeuthen site (PITZ), develops high brightness electron source for modern linac-based Free Electron Lasers (FELs). The PITZ accelerator can be considered as a proper machine for the development of an IR/THz source prototype for pump and probe experiments at the European XFEL. The radiation generated by high-gain FEL and Coherent Transition Radiation...

Accelerator applications like free-electron lasers, time-resolved electron diffraction, and advanced accelerator concepts like plasma acceleration desire bunches of ever shorter longitudinal extent. However, apart from space charge repulsion, the internal bunch structure and its development along the beamline can limit the achievable compression due to non-linear phase space correlations. In...

This poster discusses the generation of single spike SASE pulses at soft x-ray wavelength at the free-electron laser FLASH by using electron bunches of a few femtosecond duration. In order to achieve these extremely short bunch lengths, a low bunch charge of about 20pC is required. An injector laser with an adjustable pulse duration within the range of 1.7ps to 4ps FWHM and bunch charges up to...

Collective effects and instabilities due to longitudinal space charge and coherent synchrotron radiation can degrade the quality of the ultra-relativistic, high-brilliance electron bunches needed for the operation of free-electron lasers. In this contribution, we demonstrate the application of a laser-induced microbunching instability to selectively suppress the SASE process. A significant...

The free-electron laser facility FLASH at DESY operates since several years in SASE mode, delivering high-intensity FEL pulses in the extreme ultraviolet and soft x-ray wavelength range for users. In order to get more control of the characteristics of the FEL pulses, external FEL seeding has proven to be a reliable method to do so. At FLASH, an experimental setup to test several different...
