Unlocking Cryogenic Material Behaviour with Novel Cryostat

Multiple cryostats have been developed and released including; microcrack fracture toughness and shear fixtures, with others, such as impact, under development. Understanding properties of materials at cryogenic temperatures is time consuming and costly, with limited existing UK capability. Driving transformational change in the field of cryogenics, the capability introduced by NCC...

TransTech Acquires Cryogenic Technology Resources to Strengthen Cryogenic Gas Solutions

TransTech Group, a portfolio company of Bridge Industries, has acquired Cryogenic Technology Resources (CTR), a provider of engineered solutions for the industrial gas sector. The buy-out aims to strengthen TransTech’s position in the cryogenic and high-pressure gas storage and transfer market, including advanced automation and control technologies. Known for designing, fabricating,...

University of Houston Researchers Awarded New Funding for Superconductivity Project

Researchers at the Texas Center for Superconductivity and the Department of Physics at the University of Houston have received second-year funding from Intellectual Ventures, a global leader in the business of invention, to continue their important study of the retention at atmospheric pressure of high-pressure-induced/enhanced superconductivity. The project, which has...

Researchers Use High-Performance Computing to Break New Ground in Quantum Photonics

For the first time, scientists at Paderborn University in Germany have utilized high-performance computing (HPC) to perform large-scale analysis of quantum photonics, marking a significant step forward in the field. By employing customized open-source algorithms, they conducted quantum tomography on a photonic quantum detector at an unprecedented scale. This integration...

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...

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...

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...
