QED-C® Announces Four Projects Designed to Advance Cryogenics for Quantum Information Science and Technology

The Quantum Economic Development Consortium (QED-C), managed by SRI International, in strategic partnership with the U.S. Department of Commerce’s National Institute of Standards and Technology (NIST), today announced a $2.3 million research program to advance cryogenic technologies that will enable innovation in quantum information science and technology (QIST). The program aims to...

Realizing the STEP Fusion Dream

Deliver a UK prototype fusion energy plant, targeting 2040, and thereafter a sustainable, long-term pathway to the commercial viability of nuclear fusion. That’s the ambitious objective – and even more ambitious timeline – confronting the scientists, engineers and project managers currently sweating the details for the conceptual design of the...

Graphene Quantum Magic Delivers a New Class of Superconducting Material

Superconductors are materials that conduct electrical current with almost no electrical resistance at all. This property makes them particularly appealing for a variety of applications, including loss-less power cables, electric motors and generators, and powerful electromagnets that can be utilized for MRI imaging and magnetic levitating trains. Nagoya University researchers...

Transfer Lines

Transfer lines may in some real sense be thought of as the cryogenic fluid analogy of current leads. While current leads carry electrical power to where it’s required in a cryogenic system, transfer lines do the same with cryogenic fluids. Transfer lines range in complexity from very simple U-tubes containing...

Zero Boiloff

Zero Boil Off cryostats are those that contain liquid cryogens but are designed to eliminate or vastly reduce the boil off of  the liquid. These cryostats combine some of the advantages of Cryogen-Free systems (e.g. ease of use and long operational lifetime) with the advantages associated with a reservoir of liquid...

Cryomodule

Cryomodule is a term that is most commonly used to refer to cryostats that contain superconducting radio frequency (SRF) cavities. Such cavities are used to accelerate charged particle beams and are a major component of modern particle accelerators. Using the term cryomodule to refer to cryostats containing SRF cavities appears...

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...

Are there lists of existing biorepositories?

We are a relatively new Biorepository that was developed as part of a large breast cancer epidemiology study, and thus far we have accumulated DNA on over 8000 women along with extensive questionnaire, mammography, and case status data. I was wondering, are there lists of existing Biorepositories with their contents?...

Trying to design a system to store ammonia at -33°C

I am working on a project where we are trying to design a system to store ammonia at -33°C. In order to size the compressors to maintain the ammonia in the liquid state, I need to estimate the heat gained from the environment including the radiation from the sun and...
