Hybrid organic-inorganic perovskites tend to undergo several structural transformations that can be caused by temperature, humidity and light. One of the striking is light-induced halide phase segregation in mixed lead-halide perovskites, i.e., formation of I-rich and Br-rich domains by the illumination with visible light [1]. [...]

The photoinjector test facility at DESY in Zeuthen (PITZ) is developing a THz free electron laser (FEL) using its high brightness electron beams. At present, more than 100 µJ pulse energies have been demonstrated at 3 THz using 17 MeV/c electron bunches with up to 2.5 nC charge. [...]

Developments on high power tunable THz source forpump-probe experiments at the European XFEL are ongoing atthe Photo Injector Test facility at DESY in Zeuthen (PITZ). ALCLS-I undulator is used for proof-of-principle experiments atPITZ. [...]

In this talk we present Helmholtz ID at Home (HIDaH) - an OpenID Connect Provider for testing and development. Testing the integration of applications into identity federations may require relying on staging systems where arbitrary identities can't be simulated easily or require running resource-intensive identity providers on local development machines. [...]

Background and AimsThe upgraded R&D platform for electron FLASH radiation therapy – FLASHlab@PITZ, is under commissioning at the photoinjector test facility at DESY in Zeuthen (PITZ). One major purpose of the new beamline is to demonstrate the performance of a sweeping system, which scans the electron beams within one RF pulse (≤1 ms, 1-10 Hz) across the transverse plane and produces both homogeneous and spatially fractionated radiation fields at the dose rate of >106 Gy/s.MethodsIn the new beamline, an achromatic dogleg section has been installed to direct the electron beams to the experimental area with preserved high beam quality, followed by quadrupole magnets to focus and shape the beam distribution, and a sweeping system to scan the beam in the transverse plane.
