European XFEL
Soft X-ray Port (SXP)

Conceived as an open port complementing the other two baseline instruments at SASE 3, the Soft X-ray Port (SXP) instrument is primarily designed for time- and spin-resolved X-ray photo-electron spectroscopy. However, investigations of complex chemical and bio-inorganic molecular systems with fluorescence spectroscopy as well as research on highly charged ions are also envisioned. It is located behind the SASE 3 soft X-ray undulator providing photons with horizontal polarization in an energy range between 260 eV and 3000 eV exceeding 1012 photons per pulse with up to 27000 pulses/s. Two highquality elliptical mirrors in Kirkpatrick-Baez (KB) configuration can focus the femtosecond XFEL pulses to a spot size of approximately 1 μm in diameter, resulting in an intensity of more than 1018 W/cm2 in the interaction region. Together with various synchronized femtosecond optical laser (OL) systems, whose wavelength ranges can be extended into the infrared as well as extreme ultraviolet region, it will pave the way for ultrafast pump-probe investigations at the SXP instrument combining intense and tunable soft X-rays with versatile optical laser capabilities.
