Women in Cryogenics and Superconductivity 2021

CSA celebrates women in cryogenics and superconductivity. In this feature, seven women in positions across the industry discuss current projects, how they entered the field and their thoughts on attracting more women to the profession.

Linde, Bluefors to Jointly Develop Cryogenic Cooling Solutions for Large-Scale Quantum Computing Technology

On March 15, Dublin-based Linde Cryogenics (CSA CSM) and Finnish company Bluefors (CSA CSM) announced a joint operation to create cooling solutions for large-scale quantum computers. Linde is contributing its vast experience as a world leader in large cryogenic installations while Bluefors brings to the table its ultra low temperature...

Nikkiso Cryo Updates Facility to Increase Cryogenic Pump Production, Appoints New VP

On April 14, Nikkiso Cryo Inc., Las Vegas NV, (CSA CSM) a leading supplier of cryogenic submerged electric motor pumps used in the liquefied gas industry and a member of Nikkiso Clean Energy and Industrial Gases Group, announced a new facility which increases their cryogenic pump production efficiency and capability....

Who is Frosty?

You have seen the cute little white smiling CSA mascot, “Frosty,” with our logo on his tummy. You may have wondered about his story. We’ve been featuring Frosty in many iterations, especially in the CryoChronicle, with holiday themes and—more recently—with a mask reminding us to be safe during this pandemic....

Why Choose One Cryogenic Transfer Hose Over Another?

Hoses are one of the unsung heroes of cryogenics. They aren’t directly responsible for the production or storage of cryogenic liquids, nor do they make headlines in the same way that innovations enabled by cryogenics do. However, hoses are found throughout cryogenic processes and in many products like MRI machines...

Cryomech Restructures, Introduces Improved Cooler during Pandemic

While 2020’s pandemic altered “business as usual” for nearly every organization, operation and individual around the globe, some businesses took advantage of the necessary changes to reflect on their operations and expectations. Late last year, Cryomech (CSA CSM) took the opportunity and restructured internally. Now, the new—and growing—team has introduced...

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...

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...

Cryosurgery

Review of Cryosurgery Boris Rubinsky, PhD Hebrew University School of Science and Engineering Research Center for Biomedical Engineering 78b Ross Building Givat Ram, Jerusalem 91904 Israel rubinsky@cs.huji.ac.il as published in Annual Review of Biomedical Engineering, August 2000, Vol. 2, pp. 157-187. Abstract: Cryosurgery is a surgical technique that employs freezing...

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...

Power usage: cryogenic systems vs. regular refrigerators

A recent project highlighted to me that closed cycle cryogenic cooling systems use far more electrical power to reduce temperatures by a few watts than regular refrigerators. I am sure it must be something to do with the extra difficulty of removing the heat from the liquid nitrogen or similar...

Redundancy strategies for mechanical -80C freezers

I was wondering what kind of redundancy strategies are people using for their mechanical -80C freezers? I am aware of the following. Please add if you are doing something different. 1) 1 Backup freezer for every 10 freezers – Empty and maintained at -80C at all times 2) Backup C02...

Safety guidelines for handling cryo vessels of nitrogen

I am looking for any safety guidelines for handling cryogenic vessels of nitrogen indoors and outdoors. I am especially interested in recommendations for area monitors to detect leaks, flow detection devices, etc.

Method to move components in a cryogenic environment

Does anyone know of a method with which to reliably move components in a cryogenic environment? We are interested in moving detectors in a cryogenically cooled (2K) vacuum chamber, which is contained within a larger cryostat/isolation vacuum with thermal shields. As the desired horizontal or vertical displacement is between 10...
