High-resolution optical design of the sub-meV ARPES beamline at the Ultrafast Transient Experimental Facility
The Ultrafast Transient Experimental Facility (UTEF) at Chongqing University is constructing a next-generation angle-resolved photoemission spectroscopy (ARPES) beamline designed to simultaneously achieve sub-meV energy resolution, continuous photon energy tunability (10–40 eV), high photon flux (>10 12 photons s −1 at the sample position), full polarization control, and ultra-low-temperature sample environments (13 photons s −1 . A dual-endstation layout enables flexible operation for both ultra-high-resolution measurements at ultra-low temperatures and large-angle, high-flux spin-resolved experiments. Through comprehensive optical optimization—including mirror coatings, customized grating groove profiles and precision focusing geometry—the system can deliver photon flux exceeding 10 14 photons s −1 (0.1% bandwidth) −1 with a spatial beam spot size of approximately 30 µm, while maintaining sub-0.4 meV energy resolution. This work presents the optical design and projected performance of the UTEF ARPES beamline.
