    Description

    By using the technique of electrostatic velocity filtering [1] we demonstrate the production of velocity selected pulses of slow molecules from a continuous beam with a tunable center velocity. The pulses are generated by switching electric fields on adjacent segments of an electric quadrupole guide synchronously with the propagation of the molecules. We generate pulses of deuterated ammonia (ND3) containing up to 106 molecules with center velocities between 20 m/s and 100 m/s and a relative spread of (7 ± 1) %.
