Simulations of Radiation Production in the Undulator for the THz Source Project at PITZ — •Prach Boonpornprasert, Barbara Marchetti, Mikhail Krasilnikov, and Frank Stephan — Deutsches Elektronen-Synchrotron DESY, Platanenallee 6, 15738 Zeuthen, Germany

The Photo Injector Test facility at DESY, Zeuthen site, (PITZ) develops high brightness electron sources for modern linac based Free Electron Lasers (FELs). A normal conducting L-band PITZ linac delivers electron bunches of various bunch charge with low emittance and unique pulse train structure. As one possible application of such beams, this generation of IR/THz radiation is under consideration now. Based on the PITZ linac Terahertz light sources using synchrotron radiation, transition radiation and undulator radiation can provide remarkable properties. Due to its infrastructure PITZ can be considered as a proper site for the development of a THz source prototype that could be placed at the European XFEL site, allowing pump and probe experiments with X-rays and THz radiation with a time structure that is identical to that of the XFEL. On the other hand the THz/IR radiation can be used for the electron beam characterization. This work presents GENESIS1.3 simulations of the radiation produced in the undulator. The simulations were performed by considering the PITZ facility as the accelerator and adding an APPLE-II type undulator as the radiator. In this presentation the simulations setup, procedure and results will be described.
