Traveling-wave deceleration of heavy polar molecules in low-field-seeking states

N. E. Bulleid, Richard Hendricks, E. A. Hinds +4 more

We demonstrate the deceleration of heavy polar molecules in low-field-seeking states by combining a cryogenic source and a traveling-wave Stark decelerator. The cryogenic source provides a high-intensity beam with low speed and temperature, and the traveling-wave decelerator provides large deceleration forces and high phase-space acceptance. We prove these techniques using YbF molecules and find the experimental data to be in excellent agreement with numerical simulations. These methods extend the scope of Stark deceleration to a very wide range of molecules.We demonstrate the deceleration of heavy polar molecules in low-field-seeking states by combining a cryogenic source and a traveling-wave Stark decelerator.

Deceleration of a Supersonic Beam of SrF Molecules to 120 m s−1

Sreekanth Chirayath Mathavan, Artem Zapara, Quinten Alan Esajas +1 more

Abstract A beam of SrF molecules is decelerated from 290 to 120 m s−1. Following supersonic expansion, the molecules in the X2Σ (ν=0, N=1) low‐field‐seeking state are trapped by the moving potential wells of a traveling‐wave Stark decelerator. With a deceleration strength of 9.6 km s−2 the removal of 85 % of the initial kinetic energy in a 4 m‐long modular decelerator is demonstrated. The absolute amount of kinetic energy removed is a factor of 1.5 higher compared to previous Stark‐deceleration experiments. The demonstrated decelerator provides a novel tool for the creation of highly collimated and slow beams of heavy diatomic molecules, which serve as a good starting point for high‐precision tests of fundamental physics.Abstract A beam of SrF molecules is decelerated from 290 to 120 m s−1.
