Cryogenics Makes the European Spallation Source a Hot Property in Neutron Science

Cryogenics is a core enabling technology at the European Spallation Source, a next-generation neutron-science facility under construction in Sweden. In a July 6 Physics World interview, Joe McEntee talks to John G. Weisend II, CSA board chairman and group leader for specialized technical services at ESS, about the secrets of...

Two Construction Projects Reach Major Milestones at Fermi National Accelerator Laboratory

On July 22, Fermi National Accelerator Laboratory (CSA CSM) simultaneously achieved two construction milestones: the groundbreaking for its PIP-II cryoplant building and the site dedication of the laboratory’s Integrated Engineering Research Center. The two projects help usher in a new era of science and support cutting-edge research, including the international...

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...

Space Cryogenics

Space cryogenics is, somewhat obviously, the application of cryogenics to space exploration and science. The use of cryogenics in space optimizes the launching of vehicles, provides power and life support to spacecraft and is critical for many scientific observations.Space cryogenics has a number of challenges and has driven both pure...

Exergy

The science of thermodynamics plays a major role in cryogenics. It underlies the various refrigeration cycles, from Carnot to Brayton (Cold Facts Vol. 32 No. 2) and Joule-Thomson, is a fundamental part of the definition of terms such as coefficient of performance (Cold Facts Vol. 31 No. 1) and even...

Cryogenic Treatment

Cryogenic treatment is the process of cooling materials to cryogenic temperatures temporarily to improve their material properties at room temperature. This is distinct from cooling materials down to cryogenic temperatures to take advantage of phenomena such as superconductivity that only occur at cryogenic temperatures. Cryogenic treatment, sometimes also referred to...

Wind Tunnels

Dr. Robert Kilgore The development of the cryogenic wind tunnel is one of many significant breakthroughs in both cryogenics and wind-tunnel technology made during the past millennium. Interest in the development of high-speed commercial and military aircraft resulted in a review of problems of flow simulation in transonic wind tunnels...

History of Cryogenics

From the Fall 1999 issue of Cold Facts magazine Millennium Breakthroughs A variety of CSA members give different perspectives on the past millennium: What were the most significant breakthroughs in cryogenics during the past millennium? Prof. R.G. Scurlock, Kryos Technology, scurlock@soton.ac.uk (“Breakthrough” = way through obstacles — Oxford English Dictionary)...

Cryobiology

Andreas Sputtek Past President Society for Cryobiology sputtek@uke.uni-hamburg.de or http://www.sputtek.de/. The word cryobiology (from the Greek words “cryo” = cold, “bios” = life, and “logos” = science) literally signifies the science of life at low temperatures. In practice, this field comprises the study of any biological material or system (e.g.,...

Cryogenic Insulation

James E. Fesmire Cryogenics Test Laboratory NASA Kennedy Space Center james.e.fesmire@nasa.gov Introduction In today’s world, the use of cryogenics and low-temperature refrigeration is taking a more and more significant role. From the food industry, transportation, energy, and medical applications to the Space Shuttle, cryogenic liquids must be stored, handled, and...

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?
