Abstract

An atomic oven includes a cartridge and a main body. The cartridge includes a holder that accommodates an atom source; and a capillary nozzle. The main body includes: a housing in which the cartridge is installed; a button heater; an access opening for removing the cartridge from the main body and placing the cartridge into the main body, the access opening being provided on the atmosphere side, which is outside the main body; and a passage from the access opening to the housing. The cartridge is inserted into the main body through the access opening and is installed in the housing. The atom source is heated by the button heater, whereby atomic gas generated from the atom source is emitted as an atom beam to the vacuum side, which is outside the main body.

First claim

1 . An atomic beam generation device, comprising:
a cartridge that includes a holder accommodating an atom source; and a main body where the cartridge is installed, wherein the main body comprises:
an installation portion where the cartridge is installed;
a temperature adjustment mechanism that adjusts a temperature of the atom source accommodated in the cartridge installed in the installation portion;
an access port which is provided on an atmosphere side residing outside of the main body and through which the cartridge is inserted into and taken out from the main body; and
a pathway from the access port to the installation portion, and
wherein, by causing the temperature adjustment mechanism to adjust the temperature of the atom source, atomic gas generated from the atom source is emitted as an atomic beam from the main body to a vacuum side residing outside of the main body.

2 . The atomic beam generation device according to claim 1 , further comprising
a press mechanism that pushes the cartridge installed in the installation portion from a side of the access port to a side of the installation portion.

3 . The atomic beam generation device according to claim 2 ,
wherein the press mechanism pushes the cartridge toward the installation portion using an elastic spring force of a spring.

4 . The atomic beam generation device according to claim 2 ,
wherein an outer peripheral surface of the holder has a tapered shape toward a distal end of the holder, and a surface of the installation portion on which the cartridge is installed has a flared shape conforming to the shape of an outer peripheral surface of the holder.

5 . The atomic beam generation device according to claim 1 ,
wherein a threaded groove is formed in a surface of the installation portion on which the cartridge is installed, and a threaded groove meshing with the thread groove of the installation portion is formed in an outer peripheral surface of the holder.

6 . The atomic beam generation device according to claim 1 ,
wherein the cartridge further includes a nozzle integrated in the holder, and the atomic gas generated from the atom source is emitted on the vacuum side through the nozzle.

7 . The atomic beam generation device according to claim 6 ,
wherein the temperature adjustment mechanism is installed around a distal end of the nozzle.

8 . The atomic beam generation device according to claim 6 ,
wherein the atom source is an atom source that generates the atomic gas by being heated, the temperature adjustment mechanism is a heater that heats the atom source, and the nozzle is sealed with an openable seal that is melted by being heated by the heater.

9 . The atomic beam generation device according to claim 1 ,
wherein the atom source is an atom source that generates the atomic gas by being cooled, and the temperature adjustment mechanism is a cooling mechanism that cools the atom source.

10 . A physics package, comprising:
the atomic beam generation device according to claim 1 ; and a vacuum chamber that encloses a clock transition space where atoms are arranged.

11 . The physics package according to claim 10 ,
wherein the physics package is for an optical lattice clock.

12 . The physics package according to claim 10 ,
wherein the physics package is for an atomic clock.

13 . The physics package according to claim 10 ,
wherein the physics package is for an atom interferometer.

14 . The physics package according to claim 10 ,
wherein the physics package is for a quantum information processing device for atoms or ionized atoms.

15 . (canceled)
