Abstract
A quantum interference device includes a gas cell into which metal atoms are sealed, a heater that heats the gas cell, a heat transmission portion that is located between the gas cell and the heater, is connected to the gas cell, and transmits heat generated from the heater to the gas cell, and a heat dissipation portion that is connected to the gas cell so as to be spaced apart from the heat transmission portion, and dissipates heat of the gas cell.
Claims10
A quantum interference device comprising:
- a gas cell into which metal atoms are sealed;
- a heating portion that heats the gas cell;
- a heat transmission portion that is located between the gas cell and the heating portion, that is connected to a first part of the gas cell, and that transmits heat generated from the heating portion to the gas cell;
- and
- a heat dissipation portion that is connected to a second part, which is different from the first part, of the gas cell, wherein
- the heat transmission portion and the heat dissipation portion are spaced apart from each other by a gap.
