New Study Reveals When a Superconductor Truly Becomes Super

Unraveling the mystery of superconductivity at high temperatures, specifically in copper oxide materials, remains one of the most puzzling challenges in modern solid-state physics. But new multinational research has confirmed the existence of a copper-oxide-based (or cuprate) phase transition at a temperature close to absolute zero (-273°C).

SPHEREx Mission Selected to Uncover Origins of the Universe

NASA's Astrophysics Explorers Program and associated divisions are moving ahead with a new space mission designed to help astronomers understand both how our universe evolved and how common the ingredients for life are in our galaxy’s planetary systems.

New Ceramic Material Can Better Withstand Extreme Temperatures

UCLA researchers and joint collaborators have created an extremely light and very durable ceramic aerogel, a new material that could be used for applications like insulating spacecraft due to its ability to withstand severe temperature changes encountered on space missions.

CERN Focused on Transforming LHCb and Upgrading ALICE

A period of maintenance and upgrade work is well underway at CERN, part of a technical break called Long Shutdown 2. Planned LS2 projects involve either upgrading or replacing sub-detectors at ALICE, while the Large Hadron Collider team is focused on increasing the proton–proton collision rate at LHCb by a...

Success after a Three-year Sprint

ProtoDUNE scientists rushed to develop the project’s first large prototype detector, resulting in an amazing display of the technology being created for the Deep Underground Neutrino Experiment.

UCSD Students Prepared to Launch Vulcan II

A team of engineering students from UC San Diego has developed a test rocket that features a 3D printed engine that incorporates liquid oxygen and kerosene RP-1. The updated rocket is called Vulcan II, and represents a vessel the students will attempt to launch roughly six miles into the atmosphere...

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...

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...
