Cryogenic molecular beam source of ThO for a measurement of the electric dipole moment of the electron

POSTER

Abstract

A cryogenic beam of thorium monoxide (ThO) molecules in the metastable H state has been proposed as a system for measuring the electric dipole moment of the electron. We report our progress towards realizing a cold, high-flux molecular beam source of ThO, including production and buffer-gas cooling of ThO molecules and an experimental lower limit on the lifetime of the H state.
