| 1. A method of estimating a cryogenic cooling system event, comprising:
obtaining input data representative of a first parameter of a cryogenic medium in the cryogenic cooling system, wherein the
first parameter is representative of a first stage of the cryogenic medium;
calculating an expected value representative of a second parameter of the cryogenic medium in the cooling system via a predefined
physics based model, wherein the second parameter is representative of a second stage of the cryogenic medium;
obtaining second input data representative of the second parameter of the cryogenic medium in the cooling system; and
comparing the expected value to the second input data; and
correlating a difference between the expected value and the second input data to statistical data to estimate a likelihood
of the cryogenic cooling system event.
