The PG1 monochromator beamline branch houses the XUV RIXS spectrometer (named TRIXS) as a permanent experimental end-station for RIXS studies on solid samples. The instrument is designed to cover the photon energy range from 36 - 200 eV with a spectral resolving power of ~1700. The TRIXS spectrometer end-station effectively operates with two reflective off-axial parabolic mirrors and a plane-grating unit, making use of the same SX 700 type monochromator as PG2.  Kirkpatrick-Baez (KB) refocusing optics produces a fixed FEL microfocus of 5 μm (vertically) at the sample position. The facilities optical pump-probe laser is coupled to the TRIXS end-station thus allowing for time-resolved resonant inelastic X-ray scattering studies on solid samples at FLASH.The total time-resolution of the instrument for time-resolved RIXS studies in the above mentioned energy range is 170 - 300 fs FWHM.
