Time-resolved Angle-resolved Photoemission Spectroscopy (Tr-APRES) derives from the combination of the pump-probe scheme and angle-resolved photoemission spectroscopy. A Tr-APRES setup in cooperation with a high harmonics generation femto-second laser light source has just been assembled in National Synchrotron radiation research center, Taiwan. It allows us to investigate the dynamic of the electronic structure with time-, energy- and momentum-resolved information in one single measurement. In this talk, we wish to present our preliminary Tr-ARPES result conducted in NSRRC, discuss our current challenges and future planning on this system.
