The CUORE Underground Experiment Narrows the Search for Rare Particle Process

In an underground laboratory deep beneath a mountain in Central Italy, an array of crystals, chilled to within a hair of absolute zero has been steadily compiling one of the most precise measurements to date in pursuit of a rare particle process. If it is proven to exist, this process...

World’s First Hydrogen-Powered Superyacht is Here and It Is a Beauty

The world's first hydrogen-powered superyacht was unveiled last week at the Monaco Yacht Show and it made quite an impression. The model of the 367-foot yacht was the pinnacle of luxury and sophistication. The miniature model was presented by a Dutch firm called Sinot Yacht & Architecture Design. The ship,...

Development of an ISO Standard for the Testing of Insulation Materials under Cryogenic Conditions

The mission of the International Organization for Standardization (ISO) is to create reference standards that identify requirements, specifications, guidelines and characteristics that can be used consistently by manufacturers and users to ensure that materials, products, processes and services are fit for their purpose. During the past several years, a group...

Securing Flight’s Clean Future with Cryogenics and Superconductivity

Joshua Feldman, a graduate student in the University of Illinois at Urbana-Champaign’s Haran Research Group, headed by Professor Kiruba Haran, is currently working to solve a rather lofty problem… literally. He and the Haran team are addressing the uncertain outcome of airline travel in an envirocentric future by developing a...

LUX-ZEPLIN Cryostat Installed at Sanford Underground Research Facility

On October 21, crews at the Sanford Underground Research Facility (SURF) in South Dakota strapped the cryostat containing the central component of LUX-ZEPLIN (LZ), the largest direct-detection dark matter experiment in the US, below an elevator and slowly lowered it 4,850 feet down a shaft formerly used in gold-mining operations—final...

The Coolest LEGO in the Universe

For the first time, LEGO has been cooled to the lowest temperature possible in an experiment which reveals a new use for the popular toy. A team of ultra low temperature physicists at Lancaster University decided to place a LEGO figure and four LEGO blocks inside their record-breaking dilution refrigerator....

Helium II

Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...

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?
