The high-resolution ARPES experimental station (BL03U) uses the high-resolution, high-brightness vacuum ultraviolet beam of Shanghai Synchrotron Radiation Facitity (one of the best performing synchrotron radiations in the world)  and tunable deep-UV solid-state laser source, and the independently developed internationally advanced sub femtosecond ultrashort second light source, overcomes the limitations of traditional electronic structure research in detecting depth, vertical momentum resolution and time resolution, which greatly improves the research capability and efficiency of the platform. Moreover, the platform integrates ARPES，MBE and STM, which makes up for the shortage of traditional electronic structure research in samples and improves the power of material control. Energy resolution of the BL03U platform: ~1 meV (photoemission spectroscopy), momentum resolution: ~0.003 Å-1, time resolution: ~10-16 s, which is at the international advanced level.
