Spotlight: The Bucket Brigade for Atomic Physics and the Electron Dipole Moment | NIST

Title: NIST Researchers Develop “Bucket Brigade” for Atomic Physics Research

NIST/JILA researchers have created a novel instrument inspired by old-fashioned bucket brigades, using sections to trap and transport charged molecules (ions) for study. The “bucket brigade” system, which extends over a meter, allows researchers to measure the electron dipole moment – the symmetry of electrons’ poles.

The research has significant implications for understanding the early universe, as asymmetry in electrons could explain the matter-antimatter imbalance observed after the Big Bang. While the current instrument is a prototype, researchers plan to develop a longer version (10 meters) capable of housing more ions for future experiments.

Key points:
– Novel “bucket brigade” system for transporting ions
– Measures electron dipole moment symmetry
– Implications for understanding early universe
– Current prototype, future plans for longer instrument
