Canada’s TRIUMF Opens Branch at Japan’s KEK

Canada’s TRIUMF (CSA CSM) laboratory has opened a branch at Japan’s KEK, enhancing research collaborations between the two labs to explore a range of areas from the breadth and composition of the universe to the properties of advanced materials.

NASA Invests in Aerospace Technology Development

NASA has selected eight technology proposals for investment that have the potential to transform future aerospace missions, introduce new capabilities and significantly improve current approaches to building and operating aerospace systems. This year’s portfolio addresses a range of leading-edge concepts, including a method to produce “solar white” coatings for scattering...

IBM Looks to the Cloud for Quantum Computing

IBM scientists have built a quantum computer system that users can access through the cloud on any desktop or mobile device to run algorithms and experiments. It's called the IBM Quantum Experience and it's powered by quantum processors with five superconducting qubits. Signals are sent in and out of a...

Electrons Trapped in Liquid Helium Show Promise as Quantum Bits

A team of researchers from the University of Chicago, Argonne National Laboratory (CSA CSM) and Yale University has developed a method to trap and manipulate electrons, opening the door for using the particles as quantum bits. Electrons represent an ideal quantum bit, according to the team, with a "spin" that...

NASA Releases Dozens of Patents into Public Domain

NASA has released 56 formerly patented agency technologies into the public domain, making its government developed technologies freely available for unrestricted commercial use. Additionally, a searchable database is also available that catalogs thousands of expired NASA patents already in the public domain.

Cryogenically Cooled Heat Pipes Used for Refrigeration

Scientists at Brunel University London, in collaboration with Air Products PLC, have engineered a new method to build freezers using advanced cryogenically cooled heat pipe technology. The units, capable of reaching temperatures as low as -180 °C, are likely to be used for medical storage, cooling and storing samples ranging...

Space Cryogenics

Space cryogenics is, somewhat obviously, the application of cryogenics to space exploration and science. The use of cryogenics in space optimizes the launching of vehicles, provides power and life support to spacecraft and is critical for many scientific observations.Space cryogenics has a number of challenges and has driven both pure...

Exergy

The science of thermodynamics plays a major role in cryogenics. It underlies the various refrigeration cycles, from Carnot to Brayton (Cold Facts Vol. 32 No. 2) and Joule-Thomson, is a fundamental part of the definition of terms such as coefficient of performance (Cold Facts Vol. 31 No. 1) and even...

Cryogenic Treatment

Cryogenic treatment is the process of cooling materials to cryogenic temperatures temporarily to improve their material properties at room temperature. This is distinct from cooling materials down to cryogenic temperatures to take advantage of phenomena such as superconductivity that only occur at cryogenic temperatures. Cryogenic treatment, sometimes also referred to...

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...

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...

Separated layers of ice over a pipe

I want to know that why there are different layers of ice over a pipe carrying a cryogenic fluid, each layer separated with clear marks / lines? What do these layers signify?
