Space Cryogenic Workshop Recap

During a year filled with uncertainty, many were worried about the effects of the pandemic on CSA’s biennial Space Cryogenics Workshop (SCW). After much consideration and effort, we are pleased to report the successful execution of our first – and hopefully only – virtual SCW. Hosted virtually on the Remo®...

Fermilab Sees Record Performance from Next-Generation Accelerator Componen

For several years, three US Department of Energy national labs have worked together to further improve state-of-the-art particle accelerator technology. First tests of a prototype built at Fermi National Accelerator Laboratory (Fermilab, CSA CSM) show the effort has paid off, with a new component setting records. The technology under development...

ITER Takes First Steps Toward Cryoplant Commissioning

Every week since the beginning of November, a tube trailer filled with approximately 4,600 cubic meters (750 kg) of compressed gaseous helium delivers its load to the ITER cryoplant in the south of France. At a later stage, the deliveries will become more massive, as helium is delivered in liquid...

Jefferson Lab Accelerator Gets a Fresh Pair of Eyes

A newly invented detector is allowing physicists at the US Department of Energy’s Thomas Jefferson National Accelerator Facility (CSA CSM) to “see” neutrons like never before. Fresh insight from these devices has improved operation of the lab’s powerful electron accelerator, which is used in nuclear physics studies of the atom’s...

Over a Year Later, Construction Continues to Progress on PIP-II Cryoplant Building

Ground broke on the PIP-II Cryogenic Plant Building in July 2020 at Fermilab (CSA CSM) and construction began that August. This project is integral to PIP-II’s success, as the building will house cryogenic equipment that will cool the accelerator and mechanical, as well as electric utilities for the linac complex.

Cryogenic Submerged Motor Pumps Sales to Increase by 1.4x as Demand for LNG Grows by 3.8%

Cryogenic submerged motor pumps market to top $2.5 bn driven by increasing demand for natural gas. In its new study, Fact.MR offers a holistic overview of the pricing analysis and trends of the global cryogenic submerged motor pumps market. In addition, it highlights detailed information about major growth opportunities, drivers,...

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...

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...

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...
