Ratermann Keeps Valves and Industry Confidence Flowing

By Jocelyn Navarro, Ratermann Manufacturing For companies working with cryogenic and industrial gas systems, valve failure isn’t just a maintenance issue; it’s a safety risk. Pressure relief valves must operate with precision under intense thermal and mechanical stress. That’s why Ratermann Manufacturing has made valve recertification a central part of...

Lake Shore Reduces Helium Costs to Maximize Research Efficiency

By Rachael Floyd, Director of Product Management for Cryogenic Systems, Lake Shore Cryotronics The Rising Price of Helium Helium is a nonrenewable resource that is increasingly difficult to obtain reliably. Once released into the atmosphere, it is irretrievable. Limited availability and few sources of production are driving helium prices upward....

Space Cryo Workshop 2025 Sparks Collaboration Across Continents

By Wesley Johnson and Dan Hauser The 31st Space Cryogenics Workshop (SCW) was held at the Hyatt Regency Lake Tahoe in Incline Village, Nevada, from May 13 to 15, 2025, chaired by Wesley Johnson and Daniel Hauser. More than 60 scientists and engineers from around the world convened to discuss...

Tiny Cryogenic Device Cuts Quantum Computer Heat Emissions By 10,000 Times

Researchers have developed a tiny device that extinguishes one of the biggest heat sources in quantum computers, cutting their running costs and potentially bringing these machines closer to commercial reality. Most quantum computers operate at temperatures close to absolute zero (459.67 degrees Fahrenheit, or minus 273.15 degrees Celsius) using specialized cooling equipment to...

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...

Cryogenics in Space

Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...
