Capitlization of A Named Experiment

Question

I have an experiment which we call 'the krypton experiment'. In referring to the krypton experiment, should it be capitalized?

e.g.
The Krypton Experiment was used as a source of benchmark data.

or

The krypton experiment was used as a source of benchmark data.

Answer 1

Only if Krypton is a proper noun, and then only Krypton, not experiment.

The krypton experiment was used as a source – if krypton is an element.

The Krypton experiment was used as a source – if based on the process of Professor Krypton.

Compare:

the Stanford prison experiment

Capitalization exceptions are the title of a paper or film or software, or just before establishing an acronym: The Stanford Prison Experiment (SPE)

Also see the names of specific benchmark tests. The word "benchmark" is uncapitalized except where it is part of a product name.
