Here we report the first time- and angle-resolved photoemission spectroscopy
(TR-ARPES) with the new Fermiologics "FeSuMa" analyzer. The new experimental
setup has been commissioned at the Artemis laboratory of the UK Central Laser
Facility. We explain here some of the advantages of the FeSuMa for TR-ARPES and
discuss how its capabilities relate to those of hemispherical analyzers and
momentum microscopes. We have integrated the FeSuMa into an optimized
pump-probe beamline that permits photon-energy- (i.e., kz-) dependent scanning,
using probe energies generated from high harmonics in a gas jet. The advantages
of using the FeSuMa in this situation include the possibility of taking
advantage of its "fisheye" mode of operation.
