World-First in Oman

A momentous event unfolded as the world’s first-ever liquefied hydrogen carrier, Suiso Frontier, graced the shores of Sultan Qaboos Port in Muscat on August 14. Proudly crafted by the renowned Kawasaki Heavy Industries (KHI), this marks the long-anticipated debut of Suiso Frontier in the Sultanate of Oman. The name “Suiso”...

SkyWater Unveils Cryo Lab, Partners with FormFactor for Advanced RTS Noise Detection in ROIC Applications

SkyWater Technology announced earlier this year the establishment of a new cryogenic lab dedicated to characterizing random telegraph signal (RTS) noise for read-out integrated circuits (ROICs). This move is aimed at addressing the crucial need to mitigate RTS noise in order to enhance image quality and performance for ROIC customers...

Breakthrough Enables Quench Detection in High-Field Magnets for Fusion Reactors

Researchers at Berkeley Lab’s Accelerator Technology & Applied Physics (ATAP) Division have developed a method for detecting and predicting the local loss of superconductivity in large-scale magnets that are capable of generating high magnetic fields. These high-field magnets are a core enabling technology for many areas of scientific research, medicine...

NASA Rocket Hardware Prepped for Shipment to Space Coast

With Artemis teammates and media watching, United Launch Alliance (ULA) crews guided the interim cryogenic propulsion stage (ICPS) for NASA’s SLS (Space Launch System) rocket for Artemis III to the loading dock at ULA’s facility in Decatur, Alabama, July 31. ULA’s R/S RocketShip will transport the flight hardware to ULA’s...

Contract Awarded for Acquisition of Large Cryogenic System for DUNE Detectors in South Dakota

A significant milestone has been achieved in the realization of the Deep Underground Neutrino Experiment (DUNE) with the awarding of a multi-year contract for the acquisition of a large cryogenic plant. This plant will be responsible for cooling tens of thousands of tons of liquid argon, bringing the ambitious experiment...

Cryogenics at FAIR: Adaptability is Key

The Facility for Antiproton and Ion Research (FAIR) in Darmstadt, Germany, represents an ambitious reimagining of the GSI Helmholtz Center for Heavy Ion Research, one of Europe’s leading accelerator research laboratories. When it comes online for initial user experiments in 2027, FAIR will provide scientists from around the world with...

Dilution Refrigerators

Dilution refrigerators are a common technique for reaching temperatures below 1K, particularly where continuous cooling at these temperatures is required. Helium exists in two stable isotopes: 4He and 3He. Naturally occurring 3He is extremely rare, constituting less than 1 part per million of helium gas. However, 3He can be manufactured,...

Oxygen Deficiency Hazards

Oxygen Deficiency Hazards (ODH) are a significant safety issue in cryogenic facilities. ODH occurs when inert gases such as nitrogen, helium or argon displace room air and thus lower the percentage of oxygen in the space below that required for human life. OSHA defines an area as oxygen deficient if...

Kelvin Temperature Scale

The Kelvin temperature scale is the principal temperature scale used in cryogenics and science. The kelvin is also one of the seven base units in the Système International d’Unités (SI) and is the unit of thermodynamic temperature. Thermodynamic temperature is a fundamental physical quantity (like mass, length or electrical current)...

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?
