An electron momentum spectroscopy (EMS) apparatus has been developed, which employs an ultrashort-pulsed incident electron beam with a repetition rate of 5 kHz and a pulse duration in the order of picoseconds. Its instrumental design and technical details are reported, involving demonstration of a new method for finding time-zero. Furthermore, a preliminary time-resolved EMS study on the photodissociation dynamics of acetone at 195 nm is presented.
