- •
Addition of O2 to Ar makes a gainful coolant for JT cryocooling for the 90 K range.
- •
This coolant does not freeze at high altitude (low pressure) where pure Ar does.
- •
The JT cryocooling parameters of this mixed coolant remain very similar to pure Ar.
- •
A test with 20% O2 coolant with a JT cooler exhibited the viability of this idea.
