Frozen Imaging: How Cryogenic Cameras Power Unprecedented Discovery

The Legacy Survey of Space and Time (LSST) Camera in Chile and NASA’s Compact Thermal Imager (CTI) represent cutting-edge advancements in astronomical and Earth science technology. The LSST Camera, soon to be operational at the Vera C. Rubin Observatory, will survey the entire southern sky every three nights for a...

NIST Scientists Modify Common Lab Refrigerator to Cool Faster with Less Energy

In a groundbreaking development, scientists at the National Institute of Standards and Technology (NIST) have engineered a significant enhancement to the efficiency of cooling materials to temperatures near absolute zero. Through modifications to a commonly used laboratory refrigerator, they have achieved remarkable reductions in both cooldown time and energy consumption....

Fusion Power Is Now a Possible Dream

Fusion power, the Holy Grail of nuclear energy for decades, may finally be within our grasp. If the scientists and engineers at Commonwealth Fusion Systems (CFS), a company with close ties to the Massachusetts Institute of Technology Plasma Science and Fusion Center, are right, fusion is nearly ready for power market...

Atomic Spreading Produces Novel Superconductors

Custom layering. A single layer of the topological insulator WTe2 (green) was placed on top of a row of palladium seeds (each roughly 0.5 µm wide). Over time, palladium atoms spread out across the layer and formed Pd7WTe2 (blue-green). The sample is shown before heating (left), after 25 minutes at 210 °C (center),...

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

Bose-Einstein Condensate

A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...

Cold Technology for Pest Control

While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...
