Nikola Corporation Breaks Ground on Arizona Manufacturing Facility

On July 23, Nikola Corporation, a global transportation company specializing in zero-emission vehicles and infrastructure solutions, broke ground on a 1 million-square-foot manufacturing facility in Coolidge AZ. The future zero-emission facility, sitting on approximately 430 acres, will have the capacity to produce 35,000 Class 8 commercial semi-trucks annually, with the...

Attendees of all ages will be able to engage directly with sponsors and exhibitors to experience 100+ virtual STEM activities. This free virtual event will be a graphical depiction of the...

Fermilab Scientists Publish Quantum Computing Course Outline for High School Students

Based on a program developed in partnership with two local high school educators, three Fermilab (CSA CSM) researchers are offering their high school level quantum computing class outline free of charge. The module, a first of its kind in the US, encourages students ages 15-18 to "learn about quantum concepts...

Seeking the Sounds of Superfluids at Swinburne University

An Australian study headed by Swinburne University and published in late March in Physical Review Letters examines the propagation of energy as sound waves in a quantum gas, revealing for the first time strong variations in the nature of sound waves as a function of temperature. Sound waves reveal the...

The Space Station’s Coolest Experiment Gets Astronaut-Assisted Upgrade

ASA’s Cold Atom Laboratory, a facility for fundamental physics experiments on the International Space Station, underwent a major hardware upgrade with the help of astronauts Christina Koch and Jessica Meir in January. By chilling atom clouds to just above absolute zero—the lowest temperature matter can reach—Cold Atom Lab enables scientists...

CERN Demonstrator Magnet Produces a Record Magnetic Field

In February at CERN, a demonstrator magnet using superconducting niobium-tin, cooled to 1.9 kelvins achieved a peak magnetic field of 16.5 tesla on the conductor, exceeding the previous record of 16.2 tesla from 2015. The demonstrator, known as an enhanced Racetrack Model Coil (eRMC) magnet, consists of two superimposed flat...

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...

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?
