Patent ID: 10191452

Abstract:
The present invention concerns a device (1) for an atomic clock. The device has a printed circuit board (20), a heating source, and microwave conductor. The printed circuit board (20) includes a conductive piece (10) for both interrogating and heating a gas in a cell of an atomic clock. The piece (10) has a gap (11), and is arranged for containing the cell (2), so as to directly touch the cell (2) in at least one point. The heating source (40, 60) generates heat, and is connected to the piece (10). The microwave conductor (12) is arranged to be connected to the piece (10) so as to send to the piece (10) a microwave signal for interrogating the atoms of the gas in the cell (2). This device performs more than one function (e.g. heating and interrogating) and simplify the manufacturing of the atomic clock.
