World’s Most Powerful Particle Collider Upgrade Enters Next Phase with Giant Cold Boxes

By Georgina Jedikovska CERN engineers have transported two gleaming cryogenic “cold boxes” deep into the tunnels of the High-Luminosity Large Hadron Collider (HiLumi LHC), as part of the ambitious upgrade to the world’s most powerful particle accelerator. Lowered close to the ATLAS and CMS experiment detectors, the two giant pieces...

Dutch Project Quper Results in New Leiden Cryogenics Mini-fridge, Controlled by OrangeQS Juice Operating System

An inverted tabletop dilution refrigerator that can achieve millikelvin temperatures has long been the holy grail for fast-turnaround quantum technology development. It is especially useful for fast and affordable quantum chip testing. In 2023, Quantum Delta NL awarded funding to companies Leiden Cryogenics and Orange Quantum Systems for the Quper...

Ice to Fuel: NASA Tests Technology for Refueling Landers

The farther the destination, the more fuel a rocket needs. The more fuel the rocket carries, the heavier the spacecraft. The heavier the spacecraft, the more fuel it requires to launch. Experts at NASA’s Glenn Research Center in Cleveland are testing technology that could solve this problem. The CryoFILL (Cryogenic...

There and Back Again: Reimagining Cryogenic Cooling for Scalable Arrays of Dilution Refrigerators for future Quantum Datacenters

B. Hansen and G. Tatkowski Pulse tube cryocoolers are integral to current dilution refrigerator (DR) technology, which are often referred to as “dry” DRs. In this application, the cryocoolers are used to cool the two highest temperature stages of the DRs to approximately 45 K (stage 1) and 3 K...

zeroBOG™ Empowers Sustainable Operations

by Lennis Perez and Edward Tay, Sulzer The need for efficient and sustainable management of cryogenic gases extends far beyond traditional LNG applications. Enabling the recovery and reuse of boiloff gases, or BOG, across sectors such as hydrogen, e-methane and ammonia, supports the transition to low-carbon fuels and helps operators...

Liquid Air Comes of Age in Manchester

by Mark Vyvyan Robinson, Business Development Director, Highview Power As electricity systems integrate increasing volumes of renewable generation, the requirement for long-duration energy storage has become a defining challenge of the global energy transition. In northwest England, the city of Manchester and the surrounding Greater Manchester region are now home...

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 Treatment of Materials

F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding the...

Cryogenics in Space

Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...

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?
