Abstract
Magnetic fields are one of the main tools for controlling the interaction of ultracold atoms using the so-called Feshbach resonances. However, the accurate knowledge of magnetic fields within the high-vacuum chamber is significantly complicated due to the inexact knowledge of the setup geometry, the presence of magnetic parts, and other. In this paper, we demonstrate precision calibration of magnetic fields in the high-vacuum setup using microwave spectroscopy of the ground state of ultracold thulium atoms.
