Abstract
Cryocooler health monitoring systems and methods are provided. In one example, a method includes determining, for each setpoint temperature of a plurality of setpoint temperatures, a respective power applied to a cryocooler to set a cold tip of the cryocooler to the setpoint temperature. The method further includes determining a first load line associated with the cold tip based on the plurality of setpoint temperatures and the respective powers applied to the cryocooler. The method further includes determining a health metric associated with the cold tip based on the first load line and a reference load line associated with the cryocooler. Related devices and systems are also provided.
