Experts Engineer New Cryostat Design Volume

The proper design of cryostats requires knowledge of many disciplines including: cryogenic properties of materials, heat transfer and thermal insulation, instrumentation, safety, structures and seals. One of the best ways to learn about cryostat design is to study the design choices and resulting performance of previous designs. This book provides...

Technifab Restructures, Announces Three Divisions

Technifab Products, Inc. (CSA CSM) has announced organizational changes, segmenting its business into three distinct divisions—Technifab Cryogenics, Technifab CNC Manufacturing and Technifab Cryodewars.

Density of Electron Pairs Key to Cuprate Superconductivity

Physicists at the US Department of Energy's (DOE) Brookhaven National Laboratory have determined a new reason for why cuprates become superconducting at high temperature. After growing and analyzing thousands of samples of a cuprate known as LSCO for the four elements it contains (lanthanum, strontium, copper and oxygen), the team...

Major Experiments Update Results at ICHEP2016

Researchers from several of the world's major institutions made announcements during the 38th International Conference on High Energy Physics, including physicists working at CERN, the T2K Collaboration and Fermi National Accelerator Laboratory (CSA CSM).

New Material Discovery Allows Study of Elusive Weyl Fermion

Researchers at the US Department of Energy's Ames Laboratory have discovered a new type of Weyl semimetal, a material that opens the way for further study of Weyl fermions, a type of massless elementary particle hypothesized by high-energy particle theory and potentially useful for creating high-speed electronic circuits and quantum...

Sting vs. MRI, Don’t Scan so Close to Me

Researchers at Canada's McGill University didn't turn on a red light, but managed nevertheless to lure musician Sting into a lab for an unusual neuroscience study based on his brain scans. The findings, published in the journal Neurocase, offer insights into how gifted individuals find connections between seemingly disparate thoughts...

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

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...
