Sudbury Underground Lab Becomes One of the Coolest Places on Earth

Deep underground in Sudbury’s SNOLAB, a major new experiment has just reached a critical milestone. The very centre of a series of large, nested copper vessels that make up the heart of the newest and one of the most sensitive detectors in the world has now reached a temperature a hundred...

Phantom Space Acquires Thermal Management Technologies to Advance Phantom Cloud Orbital Data Center Development

Phantom Space Corporation, a leader in responsive space transportation, announced it has completed the strategic acquisition of Thermal Management Technologies, LLC (TMT), a pioneer in advanced satellite thermal components. The acquisition strengthens Phantom’s vertical integration strategy and directly supports the rapid development of Phantom Cloud, the company’s orbital data center constellation. TMT...

Spin-Polarized Fusion Fuel Project Gets a Boost

A unique “spin” on fusion energy research is under development at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility, fueling future efforts to harness the power of the stars for the world’s electrical grid.  The lab is part of a combined research endeavor exploring the survivability of a...

SuperCDM Experiment Reaches Critical Temperature to Unlock Search for Dark Matter

University of Minnesota Twin Cities researchers working on the Super Cryogenic Dark Matter Search (SuperCDMS) experiment are part of a team who successfully cooled the experiment to its base temperature—the temperature required for the superconducting detectors to become operational, which is hundreds of times colder than outer space. Reaching base...

Researchers Reveal New Method for Dialing Up Superconductivity

Researchers have discovered evidence that superconductivity can be controlled by influencing the surrounding environment, a finding that may lead to more efficient electronics down the road, according to a new study.  Superconductivity, or the ability of certain materials to conduct electric currents without any energy loss when cooled below a critical...

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...

Air Separation and Liquefaction

You are encouraged to read Cryo Central’s History...

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...

Cryogenic Finishing

The following 3 articles discuss the uses and procedures of various type of cryogenic finishing. 1) By Robin A. Rhodes, Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Cryogenic Deflashing is employed to remove undesired residual mold flash that remains on molded parts after they are removed or ejected from the...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...
