T-ReX: a facility for time-resolved optical and angle-resolved photoemission spectroscopies — •Wibke Bronsch1, Denny Puntel2, Manuel Tuniz2, Fulvio Parmigiani1,2, and Federico Cilento1 — 1Elettra-Sincrotrone Trieste, Trieste, Italy — 2Università degli Studi di Trieste, Trieste, Italy
The T-ReX laboratory at FERMI, Elettra-Sincrotrone Trieste, is a user facility for ultrafast table-top time-resolved spectroscopies [1-3]. Our facility comprises a number of time-resolved optical spectroscopy (TR-OS) setups and an endstation for time- and angle-resolved photoemission spectroscopy (tr-ARPES). The latter is connected to diverse table-top laser sources, allowing for probe energies ranging from 6 to 30 eV. In order to show how the complementarity of these setups can be beneficial for gaining more comprehensive insights on a sample system, we will present our recent experiments on the charge-density-wave materials VTe2 and VSe2, shedding light on phonon dynamics and electronic structures of the samples under investigation.
