1. A cryocooler device comprising:
a cryocooler including an input and an output, the input forming a cooling path, and a first stage that cools a working fluid in the cooling path;
a cooling loop thermally connected to the first stage that transfers heat away from the first stage towards the output of the cryocooler; and
a thermal energy storage device selectively connectable to the cooling path and the cooling loop, wherein in a first operational mode of the cryocooler device where the at least one thermal energy storage device is connected to the cooling loop where the heat to be removed at the input exceeds a cooling capacity of the cryocooler device, and a second operational mode where the at least one thermal energy storage device is connected to the cooling path where the heat to be removed is less than the cooling capacity of the cryocooler and the heat is removed from the at least one thermal energy storage device.
