Scientists Enter Unexplored Territory in Superconductivity Search

Scientists at Brookhaven National Laboratory have been trying to understand key characteristics that cause superconductivity. They have used a combination of experimental techniques to plot points in a previously unmapped region of the "phase diagram” of BSCCO, a high-temperature superconductor.

Manufacturing in the Cradle of the Cryostat

Major cryogenic projects are underway in Hazira, India, where Larsen & Tourbo Ltd is wrapping up the cryostat system designed for the ITER project in France. The company began associated work in 2015, including segments for the ITER cryostat's base section, and is now finishing its contribution with the 490-ton...

ORNL Team Recognized as Highly Cited Researchers

Fifteen scientists at the Oak Ridge National Laboratory (CSA CSM) have been named 2018 Highly Cited Researchers. The list recognizes scientists for exceptional performance, demonstrated by the production of multiple highly cited papers that rank in the top one percent by citations.

LHC Ends Second Season, Prepares for New Achievements

Expert team members from CERN turned off the Large Hadron Collider in early December, ending the successful second run of the world’s most powerful particle accelerator. The complex will be shut down for about two years, according to CERN, enabling both major upgrades and renovation work.

Cool Innovations for Clean Energy

Cryogenic technology is making it possible for liquid air, nitrogen and methane—including methane derived from cow slurry—to play roles in combating global warming. Read more about these efforts in coverage from physicsworld.

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...

Magnetic Levitation

From http://www.superconductors.org. Magnetic-levitation is an application where superconductors perform extremely well. Transport vehicles such as trains can be made to “float” on strong superconducting magnets, virtually eliminating friction between the train and its tracks. Not only would conventional electromagnets waste much of the electrical energy as heat, they would have...

Superconductivity

From Superpower website. History of Superconductivity Superconductivity was discovered in 1911 by the Dutch physicist, Heike Kammerlingh Onnes when he was able to liquefy helium by cooling it to 4 Kelvin, or -452°F. This enabled him to cool other materials close to absolute zero and investigate their electrical properties. He...

Medical Applications of Cryogenics

Neutron Therapy Cryogenics is at the heart of nuclear accelerators. Accelerators such as Fermilab’s Tevatron make neutron therapy for cancer possible. From Fermilab Today 4/20/09: Fermilab currently offers neutron therapy. But staff at Fermilab designed and built the proton accelerator used by the nation’s first hospital-based treatment center to use...

Nuclear Physics

Al Zeller National Superconducting Cyclotron Lab (NSCL) at Michigan State University zeller@nscl.msu.edu Cryogenics has a long history in nuclear physics. The technology has its origins in the use of cold traps for maintaining a vacuum, which is required to prevent beam loss and for generating high voltages used in acceleration....

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...
