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)...

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...

Presence of alloying elements in tool steels

I want to expand my knowledge of cryogenics in general and tool steels in particular. Specifically, I am keenly interested in learning about the presence of alloying elements in tool steels and how their presence in various combinations affects the performance of tool steels after cryogenic treatment.

Pros and cons of barcoding samples

I was wondering if I could ask for input on pros and cons of barcoding. We are in the process of trying to decide if we should start barcoding our samples and I’m just not sure if this is feasible for our organization. We have numerous sites all over the...
