Deceleration of neutral molecules in macroscopic traveling traps

Original · EN

A new type of decelerator is presented where polar neutral molecules are guided and decelerated using the principle of traveling electric potential wells, such that molecules are confined in stable three-dimensional traps throughout. This new decelerator is superior to the best currently operational decelerator (Scharfenberg et al., Phys.Rev.A 79, 023410(2009)), providing a substantially larger acceptance even at higher accelerations. The mode of operation is described and experimentally demonstrated by guiding and decelerating CO molecules.
