qRIXS is a novel endstation for momentum-resolved resonant inelastic x-ray spectroscopy studies the elementary excitations in three-dimensional correlated materials. The spectrometer covers a large energy range in the soft x-ray regime and is designed to be compact and flexible. It can accommodate up to five modular spectrometers to cover a large horizontal angular range simultaneously. Berkeley Lab Engineering Division designed and fabricated the endstation.
