Description
Research and development of an accelerator-based THz source prototype for pump-probe experiments at the European XFEL are ongoing at the Photo Injector Test Facility at DESY in Zeuthen (PITZ). Proof-of-principle experiments have been performed to generate a high-gain THz Free-electron Laser (FEL) based on the Self-Amplified Spontaneous Emission scheme. The first lasing with a central wavelength of 100 $\mu$m (3 THz) was observed in the summer of 2022. This contribution presents updates of the THz SASE FEL at PITZ, including recent optimization of beam transport and matching resulting in a measured FEL pulse energy of more than 80 $\mu$J, recent FEL gain curves measurements, and an upgrade plan of THz diagnostics.
