Phys. Rev. Lett. 95, 173002 (2005) [4 pages]Continuous Loading of an Electrostatic Trap for Polar MoleculesReceived 5 May 2005; published 18 October 2005 A continuously operated electrostatic trap for polar molecules is demonstrated. The trap has a volume of ≈0.6 cm3 and holds molecules with a positive Stark shift. With deuterated ammonia from a quadrupole velocity filter, a trap density of ≈108 cm-3 is achieved with an average lifetime of 130 ms and a motional temperature of ≈300 mK. The trap offers good starting conditions for high-precision measurements, and can be used as a first stage in cooling schemes for molecules and as a “reaction vessel” in cold chemistry. © 2005 The American Physical Society URL:
