Chart Industries Set to Acquire VRV Group

Chart Industries, Inc. (CSA CSM) announced its agreement to acquire VRV s.p.a. and its subsidiaries, a multinational corporation with facilities for the design and manufacture of equipment serving the cryogenic, energy and petrochemical markets.

Fermilab Awarded More than $10 million for Quantum Science

The US Department of Energy has awarded scientists at Fermi National Accelerator Laboratory (CSA CSM) more than $10 million to spur research that could revolutionize scientific understanding of nature and the very way it's investigated.

Cryogenic Cooling of Sensing Devices Conference

Cryogenic Cooling of Sensing Devices, a conference sponsored by SPIE, the international professional society for optics and photonics technology, will be held April 14-18, 2019, at the Baltimore Convention Center, Maryland. Conference chairs are Tonny Benschop, Thales Cryogenics B.V. (Netherlands); Sergey V. Riabzev, RICOR Cryogenic & Vacuum Systems (Israel); and...

Staying Chill, Even When Disaster Strikes

When most people prepare for a hurricane, they buy food and water. But when scientist Amanda Moors sees one of those big, red, pinwheel-shaped storms appear on the weather map, she buys liquid nitrogen. Moors spends a lot of time thinking about failure. Not career failure or experiment failure, but...

The ‘Gloo’ Behind James Webb Space Telescope’s Spider Technology

It takes a team of talented individuals working in unison to brainstorm, build and deliver what will become the world’s most powerful space telescope. Marcelino Sansebastian is a Senior Instrument Technician at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, who has been deeply involved with NASA’s James Webb Space...

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...

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...

Wind Tunnels

Dr. Robert Kilgore The development of the cryogenic wind tunnel is one of many significant breakthroughs in both cryogenics and wind-tunnel technology made during the past millennium. Interest in the development of high-speed commercial and military aircraft resulted in a review of problems of flow simulation in transonic wind tunnels...

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...
