Systems and methods for gettering an atomic sensor

A system for providing a reference frequency, the system comprising:

• an atomic sensor device, the atomic sensor device configured to produce a reference frequency signal, wherein the atomic sensor device comprises:
• a sensor body, the sensor body enclosing an atomic sensor;
• a gas evacuation site located on the sensor body, the gas evacuation site configured to connect to a gas evacuation device;
• a getter container coupled to an opening other than the gas evacuation site in the sensor body, the getter container comprising:
• an opening in the getter container coupled to the opening in the sensor body, such that gas within the sensor body can freely enter the getter container;
• a getter enclosed within the getter container, the getter facing away from the sensor body;
• and
• a getter securer that secures the getter within the getter container such that the getter faces away from the container opening;
• and
• a seal that seals the container opening to the opening in the sensor body;
• wherein the system further comprises a frequency dependent device coupled to the atomic sensor device, the frequency dependent device receiving the reference frequency signal.
