Foam’s future seen in space and industry

Materials designed with specialized thermal properties have been integral components of NASA's space shuttles and other launch vehicles for many years. Now, two thermal insulation systems developed by scientists at the Cryogenics Test Laboratory (CTL), a CSA Corporate Sustaining Member, at NASA's Kennedy Space Center in Florida may have application...

TEPCO to buy 800,000 tonnes of LNG from US

Gulfnews.com reports that the operator of Japan’s crippled Fukushima nuclear power station said Wednesday it plans to buy 800,000 tonnes of light liquefied natural gas (LNG) annually from the United States as it looks to cut its fuel bills. Tokyo Electric Power (TEPCO) said it had agreed to buy 400,000...

US conductor fabrication for ITER

US ITER and its vendors are moving into a new fabrication phase for the project's toroidal field magnet system. Cabling and conductor fabrication are now underway in New Hampshire and Florida for the niobium-tin wire produced in the US. All of this fabrication effort is in preparation for delivering the...

The birth of a very-high-field superconductor

The strong magnetic fields of an MRI scanner or a particle accelerator are generated efficiently by electromagnets that have superconducting wire in their coils. A group of scientists has discovered how to make better wires using a promising material known as Bi-2212. With this discovery comes the possibility of creating...

CSA mourns Donna Jung, President of International Cryogenics

It is with great regret that we report the sudden death of Donna Jung, President of International Cryogenics, a leader in the cryogenic community, a longtime CSA Corporate Sustaining Member, and a stalwart supporter of the Society.

Liquid Hydrogen

Hydrogen becomes a liquid at 20K and 1 bar. Liquid hydrogen (LH2) is an important substance in industry, transportation and research. Industrial uses of hydrogen include applications in the electronics, glass, chemical and metal processing fields. In these applications, the hydrogen is generally used as a room temperature gas but...

Superconducting Radiofrequency Cavities

Superconducting radio frequency (SRF) cavities represent an important application of cryogenics and superconductivity. SRF cavities are a technology for accelerating charged particle beams via the transfer of radiofrequency (RF) energy to the beams via resonant structures. As such, they are frequently found in large particle accelerators used for scientific research....

Thermal Radiation Shields

Actively cooled thermal radiation shields are a common feature of cryostats whose lowest temperature is less than 77K. These shields, which typically operate at temperatures between that of LN2 and 40K, block thermal radiation from higher temperatures from reaching lower temperature cryogenic components or fluids. Since the heat radiated from...

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?

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...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...
