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...

Mixed Refrigerant Cycles

Most cryogenic refrigeration systems, both large scale systems and cryocoolers, use helium as a working fluid. There are a number of advantages to helium, not the least of which is that helium remains a fluid down to the lowest achievable temperatures. In order to freeze helium, pressures of over 20...

Fountain Pumps and He II Phase Separators

Helium II (He II), the second liquid phase of the 4He isotope described in this column in Cold Facts Spring 2010 (http://2csa.us/he2), can be modeled as consisting of two interpenetrating fluids. One, the superfluid component, has zero viscosity and entropy and the other, the normal fluid component, has nonzero viscosity...

Turboexpanders

A vital technology in the refrigerators and liquefiers described in Cold Facts Volume 31 Number 3 is that of turboexpanders. These devices are rotating machines in which the process fluid (e.g., helium) does work against the turboexpander while moving from high pressure to a lower pressure and thus is cooled....

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...
