Cryogenics at the European Spallation Source

The European Spallation Source (ESS) is an intergovernmental project building a multidisciplinary research laboratory based upon the world’s most powerful neutron source. The facility will be built in Lund, Sweden. The ESS will use a linear accelerator (linac), which will deliver protons with 5 MW of power to the target...

Cryogenics Conference Moves to Dresden

Held in Dresden, Germany, for the first time, September 11-14, the international Cryogenics conference attracted 150 participants from 23 nations with 54 lectures and 28 posters presented. The exhibition comprised 18 companies. Students from the European Course of Cryogenics, sponsored by TU Dresden, which was held in the city at...

UH wind turbine superconductivity research project wins additional funding

A University of Houston engineering researcher and his team have received additional funding from the US Department of Energy (DOE) for a wind energy project that involves using superconducting wire to generate and transport electricity.

Fermilab scientists selected as APS fellows

Five Fermilab scientists have been named fellows of the American Physical Society, a distinction awarded each year to no more than one-half of 1 percent of current APS members by their peers.

Nexans and AMSC introduce fault current limiter for North American utilities

AMSC, a global solutions provider serving wind and grid leaders, and Nexans, an expert in the cable industry (both CSA Corporate Sustaining Members), recently introduced to the North American market a medium voltage superconductor fault current limiter (SFCL) solution that is designed to meet many of the challenges caused by...

“Crowning” the ITER cryostat from below solves columnar design problem

Columns are as old as civilization: for thousands of years, they have provided architects and engineers with a simple and sturdy solution to support heavy loads while leaving room to move around on the ground below. This traditional and reliable solution was to be implemented in ITER.

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...

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...

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...
