We report the stopping of an atomic beam, using a series of pulsed electromagnetic coils. We use a
supersonic beam of metastable neon created in a gas discharge as a monochromatic source of paramagnetic
atoms. A series of coils is fired in a timed sequence to bring the atoms to near rest, where they are
detected on a microchannel plate. Applications to fundamental problems in physics and chemistry are
