Optical pumping of trapped neutral molecules by blackbody radiation
Steven Hoekstra, Joop J. Gilijamse, Boris Sartakov +4
Optical pumping by blackbody radiation is a feature shared by all polar molecules and fundamentally limits the time that these molecules can be kept in a single quantum state in a…
Magnetic trapping of buffer-gas cooled chromium atoms and prospects for the extension to paramagnetic molecules
Joost M. Bakker, Michael Stoll, Dennis R. Weise +3
We report the successful buffer-gas cooling and magnetic trapping of chromium atoms with densities exceeding atoms per cm at a temperature of 350 mK for the trapped…
Alternating Gradient Focusing and Deceleration of Polar Molecules
Hendrick L. Bethlem, M. R. Tarbutt, Jochen Küpper +4
Beams of polar molecules can be focused using an array of electrostatic lenses in alternating gradient (AG) configuration. They can also be accelerated or decelerated by applying a…
Optimizing the Stark-decelerator beamline for the trapping of cold molecules using evolutionary strategies
Joop J. Gilijamse, Jochen Küpper, Steven Hoekstra +3
We demonstrate feedback control optimization for the Stark deceleration and trapping of neutral polar molecules using evolutionary strategies. In a Stark-decelerator beamline pulse…
A versatile electrostatic trap
Jacqueline van Veldhoven, Hendrick L. Bethlem, Melanie Schnell +1
A four electrode electrostatic trap geometry is demonstrated that can be used to combine a dipole, quadrupole and hexapole field. A cold packet of 15ND3 molecules is confined in bo…
Compact in-place gate valve for molecular beam experiments
Jochen Küpper, Henrik Haak, Kirstin Wohlfart +1
A high vacuum gate valve for skimmed molecular beam experiments is described. It is designed with a very short extent of only 10 mm along the molecular beam axis to minimize the di…
