(XLT), a company known for designing, building and installing thermal vacuum systems used by defense and aerospace clients for preflight testing applications.

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.

Latest in Defining Cryogenics

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...

Cryogenic Electronics

Randall Kirschman, consulting physicist, Mountain View, California ExtElect@gmail.com Cryogenic electronics—the operation of electronic devices, circuits, and systems at cryogenic temperatures—has been a valuable technology for decades. Cryogenic electronics (also referred to as low-temperature electronics, or cold electronics) can be based on semiconductive devices, on superconductive devices, or on a combination...

Particle Physics: High Energy Physics

Cryogenics and High-Energy Physics 1. From symmetry magazine: http://www.symmetrymagazine.org/cms/?pid=1000627: Cryogenics is the study of how materials behave at temperatures near absolute zero. In high-energy particle accelerators, such frigid temperatures reduce the electrical resistance of wires in superconducting magnets, increasing the magnet strength and allowing faster particle acceleration. The same holds...

HTS Degaussing Systems

From the Spring 2009 issue of Cold Facts (Volume 25, Number 2): Thanks to a joint project by the US Navy and a number of industry partners, high temperature superconducting (HTS) technology is now at the heart of an advanced degaussing system aboard the USS Higgins at the naval station...

Magnetic Resonance Imaging

From http://www.superconductors.org: An area where superconductors can perform a life-saving function is in the field of biomagnetism. Doctors need a non-invasive means of determining what’s going on inside the human body. By impinging a strong superconductor-derived magnetic field into the body, hydrogen atoms that exist in the body’s water 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?
