Strain Manipulates TaSe3 for Quantum Effects

Topological effects are predicted to have many potential uses in future electronic devices. Therefore, finding ways to control these effects is desirable. As predicted by first-principles calculations, the one-dimensional (1D) transition-metal trichalcogenide TaSe3 is a strongly topological semimetal. It has a unique atomic arrangement of two inequivalent chains; the shorter...

Cryogenics at FAIR Unleashes the Power of Discovery

The Facility for Antiproton and Ion Research (FAIR) in Darmstadt, Germany, is embarking on a pioneering mission that will transform accelerator research and expand our understanding of the universe. With its ambitious vision to explore an extensive research canvas, FAIR is set to become a global hub for scientific exploration,...

Adult Corals Have Been Safely Frozen and Revived for the First Time

Like something out of science fiction, small colonies of mature corals have been safely frozen and revived for the first time, though more work will be needed to ensure their long-term survival, researchers report reported in Nature Communications. Freezing chunks of living corals for safekeeping — or cryopreserving them —...

Cryogenic Prober Determines Quality of Qubit Devices

Germany’s first cryogenic measuring setup for the statistical quality measurement of qubit devices on 200- and 300-mm wafers has commenced operation at Fraunhofer IAF. With the newly established cryogenic on-wafer prober, researchers at the Fraunhofer Institute for Applied Solid State Physics IAF aim to gain a deeper understanding of the...

GKN, Marshall and Parker to Cooperate on Hydrogen Flight

Aerospace industry supplier GKN Aerospace is joining forces with Marshall and Parker Aerospace to explore liquid hydrogen fuel systems for aircraft. The partners plan to develop a liquid hydrogen system suitable for both fuel cell and internal combustion engine aircraft. The planned collaboration will benefit from the UK government-funded H2GEAR...

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...
