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...

Stability

Stability refers to the ability of a device employing superconductors to remain in its superconducting state after part of the superconductor transitions back to its normal conducting state due to a disturbance. While the concept can apply to many superconducting devices—transmission lines, generators, motors, etc.—it is most commonly considered in...

Cable-in-Conduit Conductors

Cable-in-Conduit Conductors (CICC) are a common form of superconducting cable used in large-scale applications. There are several varieties of CICCs, but they all consist of many small, stabilized superconducting wires contained within a conduit through which a coolant (typically supercritical He II) flows. Figure 1 shows the cross section of...

Bayonet Coupling

A bayonet coupling is a demountable joint that allows for quick and easy connection and disconnection of cryogenic components, including transfer lines, cryostats, liquefiers and refrigerators. Bayonets provide a number of advantages, chief among them the ability to connect and disconnect the bayonets while components they connect are still at...

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...

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...

Separated layers of ice over a pipe

I want to know that why there are different layers of ice over a pipe carrying a cryogenic fluid, each layer separated with clear marks / lines? What do these layers signify?
