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...

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...

Air Separation and Liquefaction

You are encouraged to read Cryo Central’s History...

Bose-Einstein Condensate

A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...

Cold Technology for Pest Control

While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...

Cryogenic Finishing

The following 3 articles discuss the uses and procedures of various type of cryogenic finishing. 1) By Robin A. Rhodes, Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Cryogenic Deflashing is employed to remove undesired residual mold flash that remains on molded parts after they are removed or ejected from the...

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...
