L-band normal conducting RF guns operating at long pulse mode and high gradient are
installed at the European X-ray Free-Electron Laser (European XFEL) and the Free-electron …

The large variety of existing and planned light sources sets specific demands on the
performance of the corresponding electron injectors which requires specific solutions. In the …

The room temperature continuous wave (CW) very-high-frequency (VHF) gun is one of the
candidates for the electron gun of the high-repetition-rate free-electron lasers (FELs). The …

Recently three RF guns were prepared at the Photo Injector Test Facility at DESY, location
Zeuthen (PITZ) for their subsequent operation at FLASH and the European XFEL. The gun …

The free-electron laser FLASH at DESY is the worldwide leading FEL user facility operating
in the VUV and the soft X-ray wavelength range. Since summer 2005, FLASH has provided …

Abstract At the Photo Injector Test facility at DESY, Zeuthen site (PITZ), high brightness
electron sources for linac based Free Electron Lasers (FELs), like FLASH and the European …

The PITZ facility is established for the commissioning and testing of electron sources for
FELs like FLASH and the European XFEL. The facility has been upgraded during the period …

Experience has shown that imaging software and hardware installations at accelerator
facilities needs to be changed, adapted and updated on a semi-permanent basis. The past …

This thesis covers three RF structures that form part of the linear accelerator for the CLARA
Free Electron Laser test facility project. The first structure is the RF photoinjector. The design …

The European XFEL project is entering the construction phase, based on the very successful
experience of the TESLA linac technology and the SASE FEL concept, now serving the …
