Device for an atomic clock

Abstract

The present invention concerns a device (1) for an atomic clock, the device comprising:—a printed circuit board (20), said printed circuit board (20) comprising a conductive piece(10) for both interrogating and heating a gas in a cell of an atomic clock, the piece (10) comprising a gap (11), and being arranged for containing the cell (2), and so as to directly touch the cell (2) in at least one point,—a heating source (40, 60) for generating heat, and connected to the piece (10),—microwave conductive means (12) and 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.
