beam dynamics simulation and optimization of an electron beam for magnetic bunch compressor commissioning at PITZ — •Ekkachai Kongmon, Prach Boonpornprasert, Xiangkun Li, Mikhail Krasilnikov, Frank Stephan, Namra Aftab, Dima Dmytriiev, Grygorii Vashchenko, Georgi Georgiev, Christopher Richard, Anne Oppelt, and Matthias Gross — Deutsches Elektronen-Synchrotron DESY, Platanenallee 6, 15738, Zeuthen, Germany

A THz free electron laser (FEL) prototype has been developed at the Photo Injector Test Facility at DESY in Zeuthen (PITZ) for obtaining high intensity radiation for THz-pump-X-ray-probe experiments at the European XFEL. In this development, a magnetic chicane was recently installed to enhance the THz FEL performance. The aim of this study was to investigate the beam dynamics in the chicane for finding the optimum machine parameters for an electron beam transportation in the experiment. The simulation was performed via ASTRA software using a 3-dimensional magnetic field of the chicane simulated with CST-EM Studio. Furthermore, the influences of the Coherent Synchrotron Radiation (CSR) on the electron beam were studied by using the OCELOT code. The simulated results indicate the possibility of obtaining on-axis trajectory and zero-momentum dispersion of the compressed beam. The commissioning results are also reported in this presentation.
