Seminar: 20 Years of Photo Electrons at the Photo Injector Test facility at DESY in Zeuthen (PITZ): High Brightness
The first seminar of the new academic year 2022-2023 will be given by Dr. Frank Stephan (DESY, Zeuthen) on 20 Years of Photo Electrons at the Photo Injector Test facility at DESY in Zeuthen (PITZ): High Brightness Electron Sources and their Applications. The seminar will take place at 16.15 UK time on Thursday 13 October at Daresbury Laboratory and will also be available via Zoom on the seminar series Indico page.
The Photo Injector Test facility at DESY in Zeuthen (PITZ) has produced high brightness beams for more than 20 years now. After an introduction on the motivation to build this R&D facility to develop and optimise high-brightness electron sources for free electron laser applications and a summary of the state-of-the-art at the end of last century, the talk will summarise the major findings and development steps for generating high-brightness electron beams, including the continuous improvement of the beam emittance, the RF gun cavities, the photo cathode laser systems and the photo cathodes. In the second part of the talk, further applications of high-brightness electron beams are discussed , such as two different beam driven plasma wakefield acceleration experiments, the generation of tunable, high peak and average power THz radiation, as well as the capabilities to study the most modern form of radiation therapy against cancer, the so-called FLASH radiation therapy.
