Description

Accelerator-based THz sources offer high energy and repetition rates, making them attractive for pump-probe experiments at X-ray free-electron lasers. The superradiant terahertz radiation generation (STERN) experimental chamber was recently successfully integrated into the European XFEL electron beamline during its long installation and maintenance period. The setup incorporates Cherenkov wakefield structures and a diffraction radiation screen to generate superradiant terahertz (THz) pulses from the electron beam, covering a combined spectral range between 0.3-30 THz.
This work describes the design and installation of the experimental hardware, with emphasis on the THz generation and transport components. It reports on the wakefield structure assembly, the 10 m transport line and the laser-based alignment of the elements inside the chamber.
