What is the core principle regarding the temperature of a measurement device used to study ultra-low temperatures?
Answer
Colder than the coldest thing it is trying to measure accurately
Any measurement device must be colder than the coldest thing it is trying to measure accurately; otherwise, the device itself contaminates the signal with its own heat.
