Here we use time- and angular-resolved photoemission spectroscopy (trARPES) studies with extreme UV probes to monitor in real time the dynamics of charge density wave melting and reformation in this material. The high energy and momentum resolution allows us to follow in details the dispersion and dynamics of transiently populated unoccupied bands and gap formation as a function of temperature and fluences. Possible nature of the CDW formation will be discussed.
