Ball Aerospace Delivers Cryostat for GUSTO

Early this year, Ball Aerospace delivered a cryostat to the University of Arizona for NASA’s Galactic/Extragalactic Ultralong-Duration Balloon Spectroscopic Terahertz Observatory (GUSTO)—a long-duration balloon mission that will map out parts of the Milky Way and Large Magellanic Cloud galaxies to determine the life cycle of interstellar gas, witness the formation...

CERN Council Endorses Building Future Circular Collider

The CERN Council announced on June 19 their endorsement of the idea of building the Future Circular Collider—a new, larger circular supercollider. The move is the first step toward building a 100 TeV, 100-kilometer circumference collider around Geneva. As part of the vote, the group also approved the launch of...

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...

Announcing SciFest All Access

Part of the USA Science & Engineering Festival, SciFest All Access will take place online from September 16-23, 2020. 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...

Liquid Hydrogen

Hydrogen becomes a liquid at 20K and 1 bar. Liquid hydrogen (LH2) is an important substance in industry, transportation and research. Industrial uses of hydrogen include applications in the electronics, glass, chemical and metal processing fields. In these applications, the hydrogen is generally used as a room temperature gas but...

Superconducting Radiofrequency Cavities

Superconducting radio frequency (SRF) cavities represent an important application of cryogenics and superconductivity. SRF cavities are a technology for accelerating charged particle beams via the transfer of radiofrequency (RF) energy to the beams via resonant structures. As such, they are frequently found in large particle accelerators used for scientific research....

Thermal Radiation Shields

Actively cooled thermal radiation shields are a common feature of cryostats whose lowest temperature is less than 77K. These shields, which typically operate at temperatures between that of LN2 and 40K, block thermal radiation from higher temperatures from reaching lower temperature cryogenic components or fluids. Since the heat radiated from...

Bose-Einstein Condensate

A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...

Cold Technology for Pest Control

While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...

Cryogenic Finishing

The following 3 articles discuss the uses and procedures of various type of cryogenic finishing. 1) By Robin A. Rhodes, Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Cryogenic Deflashing is employed to remove undesired residual mold flash that remains on molded parts after they are removed or ejected from the...

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?
