Measurements of the transverse phase space are crucial for characterizing the performance of the electron gun in a photo injector. At the Photo Injector Test facility at DESY in Zeuthen (PITZ), the 2D x and y phase spaces are separately measured with a slit-screen emittance scanner directly after the RF booster where the energy is ~20 MeV. These 2D measurements can then combined with post...
The versatile 1.3 GHz superconducting radio-frequency (SRF) gun at HZB succesfully generated first photoemission beam from a high quantum efficiency (QE) multi-alkali photocathode. This demonstrates worldwide first beam operation of a SRF gun at high repetition rate and with a robust multi-alkali Na-based photoemissionn source. The setup of the test and all sub-systems is described. The latest...
The compact STorage ring for Accelerator Research and Technology (cSTART) project at the Karlsruhe Institute of Technology (KIT, Germany) aims to explore non-equilibrium electron beam dynamics and injection of laser-plasma accelerator (LPA) bunches for the first time. The Very Large Acceptance compact Storage Ring (VLA-cSR) is also filled by a second injector that delivers ultra-short bunches...
EuXFEL is one of the leading FEL facilities worldwide. It is constantly expanding its delivery capabilities in order to meet the photon user requirements. This talk gives an overview of the active research in the area of attosecond pulse generation, coherence control and twin-pulses generation happening at DESY and EuXFEL.
The OPAL-FEL project aims to advance European XFEL capabilities for lasing in the sub angstrom regime through the generation of low-emittance electron beams. Within OPAL-FEL, we have applied a combined spatial and temporal driver laser shaping technique to optimize photoinjector emittance. Beam dynamics simulations are performed to demonstrate that the applied approach significantly reduces...
The compact storage ring project for accelerator research and technology (cSTART) is realized at the Institute for Beam Physics and Technology (IBPT) of the Karlsruhe Institute of Technology (KIT). Flexible lattice of a ring benefits variety of operation modes. Different physical experiments are planned at cSTART. In particular, deep variation of momentum compaction factor with simultaneous...
The PITZ accelerator comprises a radiofrequency (RF) photogun and an RF booster cavity, capable of generating electron beams with bunch charges of several nC and momenta of up to 22 MeV/c. To achieve higher beam current which is a key parameter for the single-pass high-gain THz FEL, bunch length compression using a four-dipole chicane installed upstream of the undulator has been studied. Using...
PITZ at DESY Zeuthen focuses on the development and optimization of high-brightness electron sources for the European XFEL. At PITZ, a thorough study of factors influencing emittance growth is carried out. Emittance growth due to space charge can be managed through precise laser pulse shaping techniques. 4D and 6D Integral brightness that incorporates not only the emittance, but electron beam...
The photoinjector test facility at DESY in Zeuthen (PITZ) is developing a THz free electron laser using its high brightness electron beams. A start-to-end (S2E) simulation for generating superradiation at 3 THz is performed to explore the potential of producing few-cycle high-energy terahertz radiation using the current THz beamline. The results will be discussed in this poster.
HZDR is planning a successor facility for the ELBE radiation source: the Dresden Advanced Light Infrastructure DALI. DALI will include a positron source, an MeV UED instrument, an optical klystron mid-IR source for 3 to 30 THz, requiring bunch lengths of 10 to 20 wavelengths, and a superradiant THz source for frequencies up to 3 THz. The bunch length for the superradiant source needs to be...
