Abstract
Ovens for atomic clocks may include a body including a cavity within the body. A plurality of heating elements may be distributed around the body, each heating element of the plurality including coils of electrically resistive material. An arrangement of the plurality of heating elements may be such that far fields of magnetic fields having opposite polarities induced by respective coils of the heating elements overlap.
Claims20
An oven for an atomic clock, comprising:
- a body comprising a cavity within the body;
- and
- heating elements, each comprising at least one coil, distributed around the body, wherein, for each of the coils configured to produce a magnetic field of a first polarity, the heating elements comprise another coil configured to produce a magnetic field of a second, opposite polarity.
A method of making an oven for an atomic clock, comprising:
- positioning a first coil of a pair of coils a first distance from a center of a cavity in a body, the first coil configured to produce a magnetic field of a first polarity;
- and
- positioning a second coil of the pair of coils the first distance from the center of the cavity in the body, the second coil configured to produce a magnetic field of a second, opposite polarity.
An atomic clock, comprising:
- a resonator positioned to receive a subject material from an oven, the oven comprising:
- a body comprising a cavity within the body;
- and
- heating elements, each comprising at least one coil, distributed around the body, wherein, for each of the coils configured to produce a magnetic field of a first polarity, the heating elements comprise another coil configured to produce a magnetic field of a second, opposite polarity.
