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...

Dilution Refrigerators

Dilution refrigerators are a common technique for reaching temperatures below 1K, particularly where continuous cooling at these temperatures is required. Helium exists in two stable isotopes: 4He and 3He. Naturally occurring 3He is extremely rare, constituting less than 1 part per million of helium gas. However, 3He can be manufactured,...

Oxygen Deficiency Hazards

Oxygen Deficiency Hazards (ODH) are a significant safety issue in cryogenic facilities. ODH occurs when inert gases such as nitrogen, helium or argon displace room air and thus lower the percentage of oxygen in the space below that required for human life. OSHA defines an area as oxygen deficient if...

Kelvin Temperature Scale

The Kelvin temperature scale is the principal temperature scale used in cryogenics and science. The kelvin is also one of the seven base units in the Système International d’Unités (SI) and is the unit of thermodynamic temperature. Thermodynamic temperature is a fundamental physical quantity (like mass, length or electrical current)...

Cryogenic Treatment of Materials

F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding the...

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...

Liquefied Natural Gas

Liquefied Natural Gas as it relates to the Field of Cryogenics John W. Bonn VJ Systems, LLC johnbonn@vjsystems-lic.com Today the world is looking for a cleaner fuel and Liquefied Natural Gas (LNG) plays a large part in achieving this goal. LNG in a liquid form is at -162°C (-259°F) and...

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...
