Abstract

Official abstract text for this publication.

An atom cell module includes an atom cell in which atoms are enclosed, a heating unit that heats the atom cell by generating heat when a current flows, and a magnetic field generator that generates a magnetic field inside the atom cell. A magnetic field at a predetermined position inside the atom cell generated by the magnetic field generator includes a magnetic field component in an opposite direction to a magnetic field at the predetermined position generated on the basis of a current flowing through the heating unit.

First claim

Opening claim text (preview).

What is claimed is: 1. An atom cell module, comprising: an atom cell in which atoms are enclosed; a heating unit that heats the atom cell by generating heat when a current flows; a magnetic detector that detects a strength of a first magnetic field generated by the current flowing through the heating unit and that generates a detection signal corresponding to the strength of the first magnetic field; a magnetic field generator that generates a second magnetic field; and a…
