The BL5-4 station is a normal incidence monochromator beam line optimized for high-resolution angle-resolved photoemission spectroscopy (ARPES) in the photon energy range of 7 - 40 eV with polarization control (circular polarizations: 7 - 40 eV, linear polarizations: 16 - 40 eV). The dedicated experimental end station is equipped with a SCIENTA R4000 electron spectrometer. This system is capable of performing ARPES experiments with a total energy resolution of a few meV and an angular resolution of 0.3°. It is also equipped with a low-temperature sample manipulator with two degree of freedom of rotation, which can be cooled down to 5 K. Because BL5-2 and BL5-4 cannot operate simultaneously, they are often shown combined as BL5-4/BL5-2. Users may choose either experimental station for their beamtime. Please confirm with the responsible beam line scientists on the readiness of desired experimental station in advance.
