Deceleration of a supersonic beam of SrF molecules to 120 m/s
We report on the deceleration of a beam of SrF molecules from 290 to 120~m/s. Following supersonic expansion, the molecules in the \(X^2\Sigma\) (\(v=0\), \(N=1\)) low-field seeking states are trapped by the moving potential wells of a traveling-wave Stark decelerator. With a deceleration strength o...

Zusammenfassung: | We report on the deceleration of a beam of SrF molecules from 290 to 120~m/s. Following supersonic expansion, the molecules in the \(X^2\Sigma\) (\(v=0\), \(N=1\)) low-field seeking states are trapped by the moving potential wells of a traveling-wave Stark decelerator. With a deceleration strength of 9.6 km/s\(^2\) we have demonstrated the removal of 85 % of the initial kinetic energy in a 4 meter long modular decelerator. The absolute amount of kinetic energy removed is a factor 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. |
