Lancaster Team Tests LEGO® as Superior Sub-Kelvin Insulator

The Ultra Low Temperature Physics Group at Lancaster University in the UK has achieved the record for coldest LEGOs in the universe by cooling the plastic toys to 4 mK in early December. Dr. Dmitry Zmeev and PhD student Joshua Chawner tested the properties of four LEGO blocks and a...

Argonne Upgrades Enable Next-Generation Experiments

Building 203 looks unassuming, but behind—and beneath—its brick exterior, researchers are performing advanced experiments and developing support systems to answer some of physics’ biggest questions. In January, Cold Facts toured the physics building at Argonne National Laboratory (CSA CSM) in Lemont IL to learn more about the ongoing upgrades from...

Clean Energy Future: The Future is Getting Colder

From the developments in cryogenic applications over the last 20 years, we can see that the world in its technological workings is getting colder. But really, the world has been getting colder for the last 150 years as advancements in mastering cold have made steady progress. Liquid air for energy...

Introducing Cool Fuel: Fueling Cryogenics for the 21st Century!

There’s no shortage of cool project areas in cryogenics these days: space, quantum computing, fusion energy, clean energy and clean transport, to name a few. These are the fields that aspiring new engineers want to work in when they pass through my office. The irony is that our cool field...

Cryogenic Industrial Gas to Play Major Role in Alternative Clean Energy

While industrial gases and cryogenics have touched nearly every sector and industrial market for decades, the global push towards alternative clean energy technology is pushing cryogenics more rapidly than ever before. As part of this push, Circor (CSA CSM) is setting new standards for a hydrogen energy world. New technologies...

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...

History of Cryogenics

From the Fall 1999 issue of Cold Facts magazine Millennium Breakthroughs A variety of CSA members give different perspectives on the past millennium: What were the most significant breakthroughs in cryogenics during the past millennium? Prof. R.G. Scurlock, Kryos Technology, scurlock@soton.ac.uk (“Breakthrough” = way through obstacles — Oxford English Dictionary)...

Cryobiology

Andreas Sputtek Past President Society for Cryobiology sputtek@uke.uni-hamburg.de or http://www.sputtek.de/. The word cryobiology (from the Greek words “cryo” = cold, “bios” = life, and “logos” = science) literally signifies the science of life at low temperatures. In practice, this field comprises the study of any biological material or system (e.g.,...

Cryogenic Insulation

James E. Fesmire Cryogenics Test Laboratory NASA Kennedy Space Center james.e.fesmire@nasa.gov Introduction In today’s world, the use of cryogenics and low-temperature refrigeration is taking a more and more significant role. From the food industry, transportation, energy, and medical applications to the Space Shuttle, cryogenic liquids must be stored, handled, and...

Cryogenic Treatment of Materials

F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding the...

Seeking recommendations for commercial sensors

I would like to measure vibrations in small LHe cryostats. Could anybody recommend commercial sensors which would be suitable for the purpose? I am interested in the frequency range between 1Hz and a couple of KHz, with particular attention to the low frequency side.

Estimating cost of carbon steel, pure helium storage tanks

In order to perform an indicative cost assessment of our helium cryogenic plant (still in the design phase), I need an estimation of the cost of carbon steel room temperature pure helium storage tanks. The storage pressure is 20 bar. Can anyone give me suggestions about how to estimate the...

Supplier of pressure sensor that works down to 4.2 K

In an actual experiment we would like to measure the static pressure in a cryostat in the range between one and four bar. Therefore we are looking for some (more or less) cheap pressure sensors that work in liquid helium in the pressure range up to five bar. Unfortunately all...

Looking for reference/textbook suggestions

Can you suggest some reference textbooks for practical thermodynamics applications in cryogenic fields? I need textbooks with cryogenics calculations and examples, dimensioning procedures, second principle applications in cryogenics, heat load calculations, cryogenic pump application, etc. Do such books exist? Does any similar source of information exist?
