Air Products Expands Operations in South China

Air Products has opened a cryogenic air separation plant in the Guangdong Province of South China. The facility will produce both gaseous oxygen and nitrogen in a modular space that allows for easier field installation and requires less land, according to the company.

LArIAT Upgrade Tests DUNE Design

Scientists from the LArIAT experiment at Fermi National Accelerator Laboratory have begun a proof-of-concept test for the planned Deep Underground Neutrino Experiment (DUNE). The researchers studying what will happen if the space between detection wires inside the future DUNE detectors is increased from three millimeters to five, a design that...

GE Healthcare Acquires Cryogenic Cold Chain Specialists

GE Healthcare has acquired Asymptote Limited, a company specializing in cryochain technology for sensitive cellular therapies. The acquisition fills a critical gap in GE Healthcare’s end-to-end ecosystem of products and services for cell therapy production, according to GE, and will be an important piece of a portfolio enabling the industrialization...

A Silver Snoopy for Valcor Top Dog

In a March ceremony, NASA presented Valcor's Yuri Gerasimov with its Silver Snoopy, an award given to candidates who have significantly contributed to the human space flight program. Less than one percent of the aerospace program workforce receives the Silver Snoopy annually, making the award a special honor. Gerasimov played...

New Material Raises Questions About Theoretical Model of Superconductivity

The US Department of Energy’s Ames Laboratory has successfully created the first pure, single-crystal sample of a new iron arsenide superconductor, CaKFe4As4, and studies of this material have called into question some long-standing theoretical models of superconductivity.

The Life of an Accelerator

Tens of thousands of accelerators exist around the world, producing powerful particle beams for the benefit of medical diagnostics, cancer therapy, industrial manufacturing, material analysis, national security and nuclear as well as fundamental particle physics. Particle beams can also be used to produce powerful beams of X-rays.

Helium-3

Helium-3 (3He) is one of the two stable isotopes of helium. The other is the much more common Helium-4 (4He). Neither of these isotopes should be confused with He II, which is the second liquid phase of 4He. He II was discussed in this column in the Spring 2010 edition...

Cryopumping

Cryopumping refers to the use of cryogenic temperatures to produce vacuum in enclosed spaces. More broadly, it can also refer to the removal of gases via cryogenic temperatures from a flow stream or enclosure without necessarily resulting in vacuum pressures. This is an important application of cryogenics and is used...

Thermal Acoustic Oscillations

Thermal Acoustic Oscillations (TAO) are a common event in cryogenic systems that can have significant adverse effects on the performance of the system. TAOs are sustained pressure oscillations that can occur in tubes containing gas, closed at one end (the warm end) that have a very large temperature gradient along...

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...
