Description

technical field [0001] The invention relates to the field of hydrogen atom frequency standards, in particular to a hydrogen source device, a manufacturing method thereof, and a hydrogen atom frequency standard. Background technique [0002] As we all know, time or frequency is one of the basic physical quantities. Experiments have proved that the transition of the microscopic quantum state has a stable and periodic signal, so it can be used as a time or frequency measurement standard, that is, the quantum transition of the atomic microscopic movement is used as the quantum frequency standard. Accurate timing supports our daily life. Many technologies we rely on in our lives, such as mobile phones, the Internet, and satellite navigation systems, all rely on the accurate timing of atomic frequency standards. [0003] The hydrogen atomic frequency standard has high short-term and long-term frequency stability. At present, the hydrogen atomic frequency standard is the most supe...
