Hyundai Nexo Sets Hydrogen Fuel Cell Distance Record

Celebrity explorer Bertrand Piccard drove Hyundai’s Nexo SUV 484 miles across France in November, setting a new world record for the longest distance traveled in a hydrogen-powered vehicle on a single tank. Within the category of zero-emissions options, the hydrogen fuel cell is constantly being eclipsed by electric power. But...

Jefferson Lab Scientists Are Designing Accelerators that Could Help Clean the Environment

Physicists at Jefferson Laboratory are working on two accelerator designs they hope could change water treatment. It’s been 30 years since a pilot project in Miami-Dade County found that blasting wastewater with electrons could clean it up—from microorganisms to harsh chemicals. Fay Hannon is designing a low-energy, portable accelerator for...

Cryogenics Secures Volatile Car Batteries in Transit

Early in December, researchers from Warwick Manufacturing Group (WMG) at the University of Warwick UK, in collaboration with Jaguar Land Rover engineers, froze batteries with liquid nitrogen. Research suggests this would allow lithium car batteries—costly and dangerous to move—to be transported safely in a much cheaper and environmentally friendly way.

Electronic Map Reveals ‘Rules of the Road’ in Superconductor

In a study published in the American Physical Society journal Physical Review X (PRX) in early December, Rice University physicist Ming Yi and colleagues offer up a band structure map for iron selenide, a material that has long puzzled physicists because of its structural simplicity and behavioral complexity. The “roadmap,”...

Tour ITER in Virtual Reality

ITER, the world’s largest fusion tokamak, is currently under construction in southern France. Now, operational facilities are under construction including the First Plasma plant and tokamak building. The consortium, comprising representatives from 35 nations, has introduced an interactive worksite tour to keep the public informed on site progress and encourage...

European Space Agency Approves Record Budget To Meet New Challenges

European Space Agency (ESA) members approved a record $15.97 billion budget in late November in Seville, Spain, to secure Europe's position in space exploration as the United States and China press ahead. Funding will allow ESA a full series of programs and additional scientific work including increased Earth observation to...

Transfer Lines

Transfer lines may in some real sense be thought of as the cryogenic fluid analogy of current leads. While current leads carry electrical power to where it’s required in a cryogenic system, transfer lines do the same with cryogenic fluids. Transfer lines range in complexity from very simple U-tubes containing...

Zero Boiloff

Zero Boil Off cryostats are those that contain liquid cryogens but are designed to eliminate or vastly reduce the boil off of the liquid. These cryostats combine some of the advantages of Cryogen-Free systems (e.g. ease of use and long operational lifetime) with the advantages associated with a reservoir of liquid...

Cryomodule

Cryomodule is a term that is most commonly used to refer to cryostats that contain superconducting radio frequency (SRF) cavities. Such cavities are used to accelerate charged particle beams and are a major component of modern particle accelerators. Using the term cryomodule to refer to cryostats containing SRF cavities appears...

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...

Liquefied Natural Gas

Liquefied Natural Gas as it relates to the Field of Cryogenics John W. Bonn VJ Systems, LLC johnbonn@vjsystems-lic.com Today the world is looking for a cleaner fuel and Liquefied Natural Gas (LNG) plays a large part in achieving this goal. LNG in a liquid form is at -162°C (-259°F) and...

Food Processing

Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...

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?
