  Angle-resolved photoemission spectroscopy (ARPES) is one of the most powerful
experimental techniques in condensed matter physics. Synchrotron ARPES, which
uses photons with high flux and continuously tunable energy, has become
particularly important. However, an excellent synchrotron ARPES system must
have features such as a small beam spot, super-high energy resolution, and a
user-friendly operation interface. A synchrotron beamline and an endstation
(BL03U) were designed and constructed at the Shanghai Synchrotron Radiation
Facility. The beam spot size at the sample position is 7.5 (V) $\mu$m $\times$
67 (H) $\mu$m, and the fundamental photon range is 7-165 eV; the ARPES system
enables photoemission with an energy resolution of 2.67 meV@21.2 eV. In
addition, the ARPES system of this endstation is equipped with a six-axis
cryogenic sample manipulator (the lowest temperature is 7 K) and is integrated
with an oxide molecular beam epitaxy system and a scanning tunneling
microscope, which can provide an advanced platform for in-situ characterization
of the fine electronic structure of condensed matter.
