Continuous loading of an electrostatic trap for polar molecules
Abstract
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/cm3 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.
