Rydberg atom electric field sensors are projected to enable novel capabilities for resilient communications and sensing. This quantum sensor is small-size, highly sensitive, and broadly tunable, and it has the potential for performing precision vecto

We present a compact, two-stage atomic beam source that produces a continuous, narrow, collimated and high-flux beam of rubidium atoms with sub-Doppler temperatures in three dimensions, which features very low emission of near-resonance fluorescence

We measure the ac Zeeman force on an ultracold gas of $^{87}\mathrm{Rb}$ due to a microwave magnetic field targeted to the 6.8 GHz hyperfine splitting of these atoms. An atom chip produces a microwave near field with a strong amplitude gradient, and

We report progress toward the development of a chip-based cold atom trap based on nanoscale waveguides, which incorporates a fabricated two-wire magnetic trap to assist in transferring laser-cooled atoms to the waveguides.

We present a dual chamber atom chip apparatus for generating ultracold (87)Rb and (39)K atomic gases. The apparatus produces quasi-pure Bose-Einstein condensates of 10(4) (87)Rb atoms in an atom chip trap that features a dimple and good optical acces

We present progress towards using atom chip-based RF and microwaves to trap and spatially manipulate ultracold rubidium and potassium. We also investigate the use of RF evaporation in such traps.

A miniaturized time-of-flight (TOF) mass spectrometer utilizes an end-cap reflectron to achieve high kinetic energy focusing and improved mass resolution. However, the coaxial geometry gives rise to considerable losses in sensitivity resulting from r

A matrix-assisted laser desorption/ionization (MALDI) time-of-flight (TOF) mass spectrometer was developed which uses a novel reflectron composed of a grounded cylinder and an adjustable endcap electrode to provide high-order kinetic energy focusing
