Sorry, no etymologies found.
This is accomplished by packing it in a cryostat, which is basically a large thermos filled with solid hydrogen.
The stainless steel quarto plates, made out of low cobalt 304, will be used in the cylindrical section of the cryostat, which is the hull surrounding the main components of the Tokamak reactor.
A bottle-like chamber, called a cryostat, surrounds and cools the telescope and detectors.
The cryostat is expected to keep the instrument cool enough for about 10 months of observation after the launch.
The detector itself has to be near 1 degree Kelvin to eliminate noise radiation from the surrounding environment, which is why it is located at the frigid South Pole, and placed inside of a cryostat.
I am very glad I never had to build this version of the instrument I had conceived, but I did learn a lot about what could be done, and I learned about the IRAS mission, which was to have a large helium cryostat much like the one we needed for the COBE.
Liquid helium boils rapidly, creating large asymmetric pressures inside the magnet cryostat.
Anyone doing a low-temperature experiment should head to the Bay Area for the weekend and leave your cryostat systems at home!
A fall into the yawning gap between the two CCDs (almost a millimetre wide!) would expose me to the - 120C temperature deeper inside this cryostat, killing me instantly as my suit failed.
Somewhat ironically, I got a second cryostat two years later.
