Cold Facts Digital – The go-to place for Cryogenics and Superconductivity

Once complete, ITER will run fusion experiments using five times as much plasma as the largest reactors in operation today.

5,500 Superconducting Wires Survive Intense Testing for World’s Largest Fusion Reactor

By Gayoung Lee Stakeholders around the world are vying to realize nuclear fusion—a fossil fuel alternative that promises maximum energy generation with minimal environmental risk. Behind the efforts to build the world’s largest fusion reactor is an equally gigantic global collaboration: ITER, which has just announced a major advance in its quest...

The Future Is Frozen: How Cryogenics Is Redefining Food Innovation

By Douglas Hoon By Douglas Hoon, CTO and Co-Founder, Cometeer, Inc Key takeaways: Once relegated to the cold backrooms of industrial storage, cryogenics is now stepping into the spotlight as one of the most promising frontiers in food innovation. Long seen as a basic preservation tool, freezing is being reimagined—not...

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....

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...

Magnetic Levitation

From http://www.superconductors.org. Magnetic-levitation is an application where superconductors perform extremely well. Transport vehicles such as trains can be made to “float” on strong superconducting magnets, virtually eliminating friction between the train and its tracks. Not only would conventional electromagnets waste much of the electrical energy as heat, they would have...

Superconductivity

From Superpower website. History of Superconductivity Superconductivity was discovered in 1911 by the Dutch physicist, Heike Kammerlingh Onnes when he was able to liquefy helium by cooling it to 4 Kelvin, or -452°F. This enabled him to cool other materials close to absolute zero and investigate their electrical properties. He...

Medical Applications of Cryogenics

Neutron Therapy Cryogenics is at the heart of nuclear accelerators. Accelerators such as Fermilab’s Tevatron make neutron therapy for cancer possible. From Fermilab Today 4/20/09: Fermilab currently offers neutron therapy. But staff at Fermilab designed and built the proton accelerator used by the nation’s first hospital-based treatment center to use...

Nuclear Physics

Al Zeller National Superconducting Cyclotron Lab (NSCL) at Michigan State University zeller@nscl.msu.edu Cryogenics has a long history in nuclear physics. The technology has its origins in the use of cold traps for maintaining a vacuum, which is required to prevent beam loss and for generating high voltages used in acceleration....

TS diagram for helium

Where can I obtain a really big, nice TS diagram for helium ?

Reliability and mounting of electronic substrates at low temperatures

I am currently working on the design of a focal plane assembly to be implemented on a small satellite (4 EMCCD detectors) to be operated at -80°C (which is not really cryogenic and likely still considered boiling hot for most of you :-). As it is passively cooled, the assembly...

Are 3D drawings included in the sale of a cryogenic plant?

I have a question concerning the 3D drawings of a cryogenic plant. The integration of the 3D drawings of a plant with the 3D main model of a new laboratory or a new facility can be a complex work that takes a lot of time. I would like to know...

Looking for a source of LOX impact testing to ASTM D2512
