Abstract
The cylindrical chamber allows one to quickly package a test fixture with attached sample, cool it to liquid-nitrogen temperature in a few minutes, and warm it back up to room temperature in a few minutes in a dry, helium or nitrogen atmosphere, which prevents water or ice from condensing on the test fixture and sample.
