Stopping Supersonic Beams with an Atomic Coilgun
  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 micro-channel plate. Applications to fundamental problems in physics and chemistry are discussed.
