BESSY II Experiment Cools 10 Million Ions to 7.4 K

Scientists at BESSY II in Berlin have developed an experimental method that cooled 10 million ions to 7.4 K for the first time. The new ion trap they created provides an opportunity to use cryogenic X-ray spectroscopy to study the magnetism and ground states of molecular ions. It is also,...

Brooks Automation Acquires Cool Lab, LLC

Brooks Automation, Inc. (CSA CSM) announced on Nov. 29 that it has acquired Cool Lab, LLC, a subsidiary of BioCision, LLC. Cool Lab provides a range of innovative, patented and patent-pending applications for sample cooling and freezing, controlled rate freezing, portable cryogenic transport and archival storage solutions for temperature sensitive...

New MRI Magnet Requires only 20 Liters of Helium

GE Healthcare has announced Freelium, a magnet technology that operates with 20 liters of liquid helium compared to the 2,000 liters needed by conventional MRI magnets. Hospitals using the technology, according to GE, would no longer require the extensive venting that often necessitates siting a magnet in a separate building...

India Set to Become Associate Member State of CERN

At an event on Nov. 21, Fabiola Gianotti, CERN's director general, and Sekhar Basu, chairman of the Indian Atomic Energy Commission and secretary of India's Department of Atomic Energy (DAE), signed an agreement admitting India to CERN as an Associate Member.

Bruker and Oxford Reach Deal for Superconducting Wire Business

The Bruker Corporation has closed a deal with Oxford Instruments for the $17.5 million acquisition of Oxford's Superconducting Wire LLC (OST). In the transaction, Bruker Energy and Supercon Technologies, Inc. (BEST), a Bruker subsidiary, acquired all shares of OST and announced the intent to fold the Carteret NJ based company...

Gecko-Inspired Adhesive Withstands Extreme Temperatures

Researchers have developed a new dry adhesive that bonds in temperatures ranging from -320°F to 1,832°F, a quality that could make the product ideal for space exploration where shade can be frigid and exposure to the sun blazing hot. It features vertically aligned carbon nanotubes with tops bundled into nodes...

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...

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...

Seeking alloy that keeps elastic property down to 10K

I am looking for a metal (alloy) that supports high temperatures (at least 1600K) and keeps its elastic property at low temperatures down to 10K. Rhenium is a good one because it does not become brittle. But it is quite expensive. Pure tungsten and molybdenum enter in the brittle regime...

Searching for a freezer that does not need electricity

I’m student of University of Barcelona. We do technical cryogenic research and we are searching for a cryogenic portable freezer that does not need electricity. We can’t find any company that offers something like this. The product we are looking for is the typical portable freezer for food or drinks...

FEP Encapsulated O rings in the cryogenic process

Can you please advise if FEP Encapsulated O rings are used within the cryogenic process and what materials? I have been asked by my company to write about FEP Encapsulated O rings for a training seminar.

Need material property data for polycrystalline / sintered ceramics

I am a ME grad student currently working on the design of a detector array / focal plate of a scientific space instrument operating at a temperature of about -80…-100°C. Although this is not in the cryogenic temperature range, I would like to address two questions to you as the...
