Manufacturers Complete Cryogenic Tank Delivery to ITER

European manufacturers have delivered the last of the 11 cryogenic tanks contracted for the cryoplant at ITER. The manufacturing of all components was undertaken by Air Liquide advanced Technologies (CSA CSM) and its subcontractors, while logistics were handled by DAHER. The ITER fusion machine will require a massive refrigerator to...

Celebrate Dark Matter Day

On October 31, 2017, institutions worldwide will celebrate Dark Matter Day with events highlighting the experiments that could bring us closer to solving the cosmic riddle of dark matter. The Interactions Collaboration, an international community of particle physics communication specialists, is the celebration's sponsor. Information on local events is available...

MagLab Awarded DOE Grant to Develop New SRF Cavities

The National High Magnetic Field Laboratory (MagLab, CSA CSM) is playing a role in a nationwide effort to make human-scale particle accelerators for a host of applications. And now, with a $1 million grant from the US Department of Energy, scientists at the lab's Applied Superconductivity Center (ASC) are developing...

Advancing Tissue Engineering with 3-D Cryoprinting

The importance of additive manufacturing (AM) and 3-D printing has increased in almost every field of engineering, including biomedical engineering, a field where researchers are advancing applications such as 3-D cryoprinting. The technology is poised to develop into an important step in tissue engineering as it can produce biological tissues...

NASA Awards Funding to Support Professional Development Programs for STEM Educators

NASA’s Glenn Research Center in Cleveland has awarded approximately $125,000 to schools and organizations to launch professional development programs for science, technology, engineering and math (STEM) educators. The award is intended to strengthen STEM programs for K-12 teachers across Ohio through the use of NASA content. The grant also includes...

Quantum Data Takes a Ride on Sound Waves

Yale scientists have created a device that uses sound waves to store quantum information and convert it from one form to another, all inside a single integrated chip. The device allows a superconducting artificial atom, or qubit, to exchange energy and quantum information with a high-frequency bulk acoustic wave resonator....

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...

Food Processing

Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...

Primary Standards

Elie K. Track Hypres, Inc. elie@hypres.com http://www.hypres.com/ Primary standards involve the exact definition and realization of units of measurement for various quantities, time, length, mass, voltage, resistance, current, etc. International agreements based on the latest scientific knowledge define those units, and their realizations vary depending on the unit itself. For...

Shrink Fitting

Robin A. Rhodes Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Shrink fitting, (or “compression fitting” as it is sometimes called), is a method used to insert a pin or bushing into a housing or other assembly requiring an extremely tight tolerance fit. It can be used as an alternative to...

Telecommunications

From the Winter 2004 issue of Cold Facts magazine The recent M-Calc IV — 4th Industry Assessment workshop discussing military and commercial applications for low-cost cryocoolers, held in November in San Diego, highlighted progress being made in cryogenics as applied in telecommunications. The reliability and long lifetime of projects now...

Cryogenic thermophysical property data

I am in search of information regarding cryogenic thermophysical property data, specifically, Thermal Conductivity, Thermal Expansion, Stiffness and Modulus, in the 20K range. My list of materials include: Ti-6AL-4V (ELI), Al 6061-T651, and Invar (36%, plus any other composition which might have data available). Other materials which would be helpful...
