The dynamics of a Rydberg Stark wavepacket above the saddlepoint of the combined Coulomb-electric field potential is investigated by conventional pump-probe techniques and an atomic streak camera. This new device records when the electron is ejected from the autoionizing system. With some modifications this streak camera can also be used to measure the shape of infrared laser pulses with a picosecond time resolution.
