Example Sentences
Recent Examples on the Web Hitchcook said researchers who were developing the cryogenics used devices from Keithley Instruments, which are made to measure temperature changes at incredible accuracy even at the below freezing temperatures used in space. 
Sean Mcdonnell, cleveland, 15 July 2022 In a seeming paradox, atoms trapped with lasers can be cooled to micro-Kelvin temperature within the QPU without cryogenics or other refrigeration — further supporting the inherent scalability of this approach. Paul Lipman, Forbes, 3 Sep. 2021 After decades of operations, McLaughlin says, the area has become home to extremely talented engineers with valuable expertise in cryogenics, receivers, and other machinery necessary to keep a giant telescope running. Charlie Wood, Popular Science, 4 Dec. 2020 For a long time, this has been extreme cooling—like approaching absolute zero with million-dollar cryogenics extreme.
