      abstract     = {The detection of inelastically scattered soft x-rays with
                      high energy resolution usually requires large grating
                      spectrometers. Recently, photoelectron spectrometry for
                      analysis of x-rays (PAX) has been rediscovered for modern
                      spectroscopy experiments at synchrotron light sources. By
                      converting scattered photons to electrons and using an
                      electron energy analyser, the energy resolution for resonant
                      inelastic x-ray scattering (RIXS) becomes decoupled from the
                      x-ray spot size and instrument length. In this work, we
                      develop PAX towards high energy resolution using a modern
                      photoemission spectroscopy setup studying
                      Ba$_2$Cu$_3$O$_4$Cl$_2$ at the Cu L$_3$-edge. We measure a
                      momentum transfer range of 24\% of the first Brillouin zone
                      simultaneously. Our results hint at the observation of a
                      magnon excitation below 100 meV energy transfer and show
                      intensity variations related to the dispersion of
                      dd-excitations. With dedicated setups, PAX can complement
                      the best and largest RIXS instruments, while at the same
                      time opening new opportunities to acquire RIXS at a range of
                      momentum transfers simultaneously and combine it with
                      angle-resolved photoemission spectroscopy in a single
                      instrument.},
