Abstract

A tri-axial magnetic field correction coil includes a first coil group and a second coil group with respect to an X-axis direction that passes through a clock transition space in which atoms are disposed. The first coil group is a Helmholtz-type coil composed in a point-symmetrical shape around the clock transition space. The second coil group is composed in a point-symmetrical shape around the clock transition space with respect to the X-axis direction, and is a non-Helmholtz-type coil that differs from the first coil group in terms of coil size, coil shape, or distance between coils.
