An overview is provided of a next-generation toroidal angle-resolving photoemission spectrometer, currently in operation at BESSY II. The instrument features exceptional multi-detection in energy and angle, facilitating rapid full-hemisphere photoemission measurements. The instrument is ideal for band structure and Fermi Surface (FS) mapping using Angle Resolved Photoemission Spectroscopy (ARPES). Recent full-hemisphere FS measurements of a prototypical material, copper, reveal previously unseen fine structure due to lifetime broadening, demonstrating the high angular resolution and dense {kappa}-space sampling capabilities of the instrument.
